Planned Intensive Flushing Programme set to commence in Mount Farran, Old Youghal Road, Richmond Hill, Audley Place and surrounding areas. 

Uisce Éireann remains committed to addressing instances of water discolouration for affected customers and continues its work to improve water quality for homes and businesses in Cork City.

Uisce Éireann’s water quality taskforce for Cork City is undertaking a number of measures including planned intensive flushing programmes which target the areas impacted the most by discolouration. Operational teams from water services have completed intensive flushing in a number of areas to date and will shortly commence work in the Inter South Central district, which includes Mount Farran, Old Youghal Road, Richmond Hill, Audley Place and surrounding areas in the coming days.

Water Operations Lead for Uisce Éireann, Sean Lynch said: “We are continuing with our planned programme of flushing for the Northside of Cork City, subject to icy weather limitations. Our goal is to minimise the instances of discolouration for the people of Cork City in areas across Cork City, based on where reports of discolouration have been received. We are asking customers in the next planned area to watch out for the signage put in place in advance of flushing.”

This programme has proven successful in mitigating the impacts on residents and businesses in the short-term and Uisce Éireann will have carried out planned flushing in seven different areas of the city by the end of this year. Uisce Éireann is seeing a positive trend in areas that have been flushed, based on discolouration report numbers and proactive callbacks to customers.

Intensive flushing typically takes 4-6 weeks across an area. The next phase of flushing will be suspended for the Christmas holiday period and resume in the New Year. The programme involves isolating and flushing small sections of the water network to clear any build-up of sediment from the old cast iron pipes. Isolating the flushing area from the larger network in this manner minimises disruption and improves sediment removal. Clearing the pipes can result in sediment carrying through to customers’ taps resulting in increased instances of discoloured water in the short-term. This is a very different operation to the reactive flushing work that takes place following localised discolouration reports. It is very much governed by weather conditions and when icy conditions are forecast, planned flushing is paused until the weather improves.

Planned flushing has been completed at Spring Lane, Ballyvolane Road, Park Court, Meelick Park and Kemption Park.

Information for Residents and Businesses in Areas Targeted for Planned Flushing:

• Operational teams will commence flushing at 8pm on Thursday, 28 November 
• Work is carried out at night-time during off-peak usage hours, typically between 8pm & 4am. This allows the network to return to normal before the morning demand starts, reducing the potential for discoloured water at customers’ taps.
• As works progress through the area, signage will be put in place and customers are also advised to check the supply and services updates section of our website.
• Uisce Éireann continues to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes. 
• Operational teams will monitor overall weather reports weather and planned flushing activity will be postponed during icy conditions.
   

Full list of areas targeted for planned flushing:

• Mount Farran
• Assumption Road
• Rathmore Road
• Rathmore Park
• Old Youghal Road
• Richmond Hill
• Audley Place

Each area is broken down into zones for night-time works and as Uisce Éireann progresses flushing through these areas a review of the programme’s operational effectiveness will be undertaken before proceeding to the next zone.

Uisce Éireann thanks customers for their patience as we continue to work to reduce instances of discolouration across Cork City, and regrets any inconvenience caused.

Uisce Éireann remains committed to addressing instances of water discolouration for affected customers in Cork City. Its dedicated Water Quality taskforce for Cork City is undertaking a number of measures including a targeted flushing programme, accelerated network improvements and watermain rehabilitation works.  

Uisce Éireann is also progressing a €1.6 million additional investment in two new processes at the Lee Road Water Treatment Plant to enhance the manganese removal capability of the plant and minimise the impact the treated water has with the old cast iron watermain network in the city.  Whilst all the infrastructure at the plant complies with global and national water treatment standards, the additional investment in new treatment processes is part of a series of initiatives by Uisce Éireann to address water discolouration issues in Cork City.

Brian O’Leary, Uisce Éireann’s Regional Operations Manager for the Southwest, said: “We recognise that instances of discolouration are still arising in areas of Cork City and want to assure householders and businesses that our dedicated taskforce is undertaking all possible measures to minimise discolouration and address the underlying issues across the city.  “We continue to advise customers not to drink discoloured water and to contact us directly with any reports of discolouration to help us manage the response in real time and to prioritise reactive works. Callbacks to customers who have previously raised concerns over discoloured water are ongoing.”

To protect public health, Uisce Éireann is undertaking extensive sampling, including testing at customers’ taps, on the network and operational sampling at the water treatment plant. This provides reassurance that the water is compliant once running clear and assists with investigations into discolouration reports.  
Uisce Éireann has reiterated its appeal for people to report instances of discolouration so that all reports can be properly investigated.

Brian said, “Collecting this information allows us to use data visualisation techniques to identify trends and patterns, to optimise network response to discolouration reports and prioritise areas for follow on works. A proactive flushing programme has been put in place targeting the areas impacted the most by discolouration. It is successful in mitigating the impacts in the short-term, by removing large quantities of sediment that have become lodged in the ageing cast iron mains. Uisce Éireann are seeing a positive trend in areas that have been flushed, based on discolouration report numbers and proactive callbacks to customers. We will continue to prioritise areas based on the numbers of reports of discolouration received.”

Public health remains our top priority, and we want to reiterate that water is safe to drink once it is running clear. Both the HSE and EPA are regularly updated and the HSE has also been consulted for their health advice during periods of increased discolouration reports. We will continue to update the public and public representatives through website, media, social media and regular briefing sessions with Oireachtas members and City Councillors. 

Ongoing work to respond to instances of discolouration in Mount Farran.

Uisce Éireann understand the frustration of affected customers and communities in Cork who are experiencing instances of discolouration. Uisce Éireann is undertaking all possible measures to minimise discoloration and to address the underlying issues across the network, including establishing a dedicated Taskforce to manage our response. 

We have been actively responding to increased reports of discolouration in Mount Farran in recent days; including undertaking investigations on site, reactive flushing and testing across the area. 

Our initial investigations identified a passing valve which may have disrupted the water flow in the area, aggravating sediment in the pipes. Our operations team completed work to address this valve in recent days. We also identified the possible need for an additional hydrant and valve to allow for more targeted flushing in areas with more persistent reports; both of which were installed in the area on Wednesday, 30 October. Following the installation of the hydrant, flushing has been carried out and we will continue to monitor the supply in the area. 

As you are aware there is approximately 600 km of watermains in Cork City, 50% to 60% of which are made from cast iron and 100+ years old. Issues such as discolouration, bursts and leakage are unfortunately a common occurrence due to the age and deteriorating condition of the pipes.  

Uisce Éireann reiterates its advice to the public not to drink discoloured water.  In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear. If the issue remains unresolved, we encourage customers to contact us directly. The customer care helpline is open 24/7 on 1800 278 278. Customers reporting instances of discolouration help us to determine flushing locations on the network.

Please be assured that while there is no easy solution, we are prioritising the response and will continue to keep all key stakeholders informed of ongoing works and continue to issue updates on the measures being taken to resolve the matter.

Uisce Éireann respond to increased reports of discolouration following works in Friars Walk 

Information below is relevant until further updates are provided here or on our Supply and Service Updates section.

Uisce Éireann’s dedicated Water Quality Taskforce for Cork City continue to closely monitor reports of discolouration. It is undertaking a series of measures specifically to reduce instances of discolouration with a targeted flushing programme, additional proactive sampling and testing at a number of locations, along with watermains rehabilitation and replacement works.

In recent days operational teams commissioned a new trunk main on the South Quays. As this work was completed, it is likely sediment was dislodged and resulted in some increased instances of discolouration in local areas.

There was also a reduction in water to the adjoining network and, once identified, water was re-routed to restore supply to affected customers as soon as possible.

Reactive flushing commenced today in the Tower Street, Barracks Street, Mount Sion Road, Evergreen Road and surrounding areas to clear any discolouration in the network.

Uisce Éireann thanks customers for their patience during these works and regrets any inconvenience caused.

€1.6 million investment underway as part of efforts to address water discolouration issues in Cork City

Uisce Éireann is investing €1.6 million at the Lee Road Treatment Plant to further treat the source water at the intake and the treated water before it leaves the plant. Whilst all the infrastructure at the plant complies with global and national water treatment standards, the additional investment in new treatment processes is part of a series of initiatives by Uisce Éireann to address water discolouration issues in Cork City.

Uisce Éireann has invested more than €100 million in infrastructure improvements across Cork City in recent years, including the €40 million upgrade of the Lee Road Water Treatment Plant in 2022, which included the construction of a new water treatment plant and water treatment systems; and associated network upgrades including new rising and trunk watermains along with new pumping stations and flood protection works. This investment has significantly modernised and improved the overall water supply infrastructure and delivered a more secure and resilient water supply to homes and businesses across Cork City. Specialists from Uisce Éireann actively monitor the performance of the water treatment plant on an ongoing basis to ensure it is fully in line with water treatment standards. The additional processes identified are enhanced new measures which will further treat the final water before it leaves the new plant.

In addition, the Water Quality taskforce established by Uisce Éireann continues to implement a range of measures to specifically address discolouration including a targeted flushing programme, additional proactive sampling and testing at a number of locations and watermains rehabilitation and replacement works.

Brian O’Leary, Uisce Éireann’s Regional Operations Manager for the Southwest, said: “Good progress has been made to advance two new processes, one to remove manganese and a second to condition the final water. In recent years, we have identified increased instances of the naturally occurring mineral, manganese, in raw water, in a number of water supplies across the country. In Cork we have expediated the installation of the manganese removal step partly in response to an event at the end of August which saw elevated levels of manganese detected in the network. The manganese removal system should be in place by the end of 2024, while the scheduled completion date for the installation of all works is mid 2025.

This is in addition to our ongoing measures to reduce instances of discolouration for homes and businesses across Cork City. As part of this effort, targeted flushing works are now taking place in Ballyvolane and we have increased sampling in 2024 including testing at customers’ taps, on the network and operational sampling at the water treatment plant. Mains rehabilitation works are also underway in Cork City, with an investment of approximately €500 million required, across several decades, to replace the entire cast iron mains network, some of which dates back to the late 1800s.”

Public health remains our top priority and water is safe to drink once it is running clear. We continue to encourage customers to contact us directly in the event of discolouration. The customer care helpline is open 24/7 on 1800 278 278. Each report is actioned, giving us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas.

We recognise that instances of discolouration are still arising in areas of Cork City and want to assure householders and businesses that our dedicated taskforce is undertaking all possible measures to minimise discolouration and address the underlying issues across the city. As part of Uisce Éireann's continuing commitment to keep the community informed on work underway to address water quality issues in Cork City, we met with elected representatives in Cork City recently to update them and will continue to keep elected representatives and all stakeholders updated as work progresses.

As part of Uisce Éireann's continuing commitment to keep the community informed on work underway to address water quality issues in Cork City, we met with Cork-based Oireachtas Members today to update them on the measures being taken to tackle discolouration and the progress being made by our dedicated taskforce.

Protecting public health is the top priority for the taskforce. Water is safe to drink once it is running clear. To protect public health, Uisce Éireann has increased sampling in 2024 including testing at customers’ taps, on the network and operational sampling at the water treatment plant.

Monitoring of the raw water source, and treated water from the Lee Road Water Treatment Plant, indicated raised levels of manganese from 27th – 31st August. In line with standard procedures Uisce Éireann consulted with the HSE and communicated to the EPA.

Manganese is a naturally occurring metal that is found in many soils, lakes and rivers. While a small amount of manganese is good for human health, the HSE advise that exposure to high manganese levels on an ongoing basis in drinking water can be a risk to health.

The HSE did not recommend any restrictions on the water supply and requested further testing. Ongoing monitoring at the water treatment plant since the weekend has shown a downward trend in the levels of manganese. Sampling is ongoing and we are continuing to share the results and liaise the HSE.

Uisce Éireann commenced a reactive flushing programme in a number of areas across Cork City last weekend and issued communications to media and all elected representatives again emphasising public health messaging and to run the water until clear.

We continue to encourage customers to contact us directly in the event of discolouration. The customer care helpline is open 24/7 on 1800 278 278. Each report is actioned, giving us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas.

Cork City water network flushing to take place on Saturday, 20 July from 9am to 4pm

Uisce Éireann’s dedicated Water Quality Taskforce, in partnership with Cork City Council, continue to work to reduce instances of discolouration for homes and businesses across Cork City. 
As part of this effort, targeted flushing works will take place in six areas across the city on Saturday 20 July. These flushing works are in response customer reports of discoloured water.

Flushing is set to commence at 9am on Saturday 20 July and expected to continue until 4pm. As works progress through an area, signage will be put in place.

Water Operations Lead for Uisce Éireann, Sean Lynch said: “Our goal is to minimise the instances of discolouration for the people where reports of discolouration have been received. Areas are prioritised based on customer feedback and reports directly to our customer care team.The works involve flushing sections of the water network to clear any build-up of sediment from old cast iron pipes.”

Flushing will take place in the following areas:

• Marble Hall Park, Castlegreina Park, Carrigeen Park, Bernadette way, Yorkboro, Haig Gardens, Glenanaar, Boreenmanna Road junction from Rockboro Avenue to junction with Victoria avenue.
• Belfield Abbey, Cherry Court, Glencoo Lawn, Glencoo Park
• Greenmount Buildings, Greenmount Avenue, Green Street, McCurtain Villas, Wycherley Place
• Spriggs Road, Kerryhall Road, Sunvalley Drive, French’s Villas, Vincent’s Avenue
• Cahergal Park, Cahergal Lawn, Gordan’s Hill
• Avonmore Park, Corrib Lawn, Ballinderry Park

Flushing involves moving water through pipes at a faster rate than the normal flow to help remove debris and sediment that may be lodged in these pipes. Clearing the pipes in this way can result in temporary water discolouration.

Uisce Éireann would like to thank customers for their patience, and regrets any inconvenience caused.

Uisce Éireann continues to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear.

Uisce Éireann’s dedicated Water Quality Taskforce continues to address water discolouration issues for affected customers in Cork City

Progress is being made on a range of areas including a targeted flushing programme, monitoring of the performance of the Lee Road Water Treatment Plant and watermain rehabilitation works.

Brian O’Leary, Uisce Éireann’s Regional Operations Manager for the Southwest, said: “Our dedicated Taskforce is undertaking all possible measures to minimise discoloration and to address the underlying issues across the region. Public health remains our top priority and we want to reiterate that water is safe to drink once it is running clear. 

“We continue to advise customers not to drink discoloured water and to contact us directly with any reports of discolouration to help us manage the response in real time and to prioritise reactive works. Callbacks to customers who have previously raised concerns over discoloured water are ongoing.”

To protect public health, Uisce Éireann has increased sampling, including testing at customers’ taps, on the network and operational sampling at the water treatment plant. This provides reassurance that the water is compliant once running clear and assists with investigations into discolouration reports. In addition, accelerated network improvements are underway and further works are planned to optimise the water supplied.

Targeted flushing programme 

The goal of the proactive flushing programme is to address discolouration issues by removing the sediment that has become lodged in the aging cast iron mains. Flushing was recently completed in Gurranbraher and Blarney Street, as well as in the Douglas area and is ongoing in the Northside of the city in the Murmount and Montenotte areas. 

Beginning the first week of July, flushing will also take place in the Ballyvolane area over a seven-week period.  We have identified several other areas for flushing in the Cork City area which are scheduled for completion by the middle of November this year.  We are seeing a positive trend in areas that have been flushed to date and, on this basis, we expect these works to lead to further improvements in water quality. 

Water Treatment Plant

Specialists from Uisce Éireann are monitoring the performance of the recently upgraded Lee Road Water Treatment plant.

The treatment process used at the Plant is fully in line with water treatment standards used nationally and globally. Raw water and its associated treatment requires continuous optimisation and monitoring as no two water sources are exactly the same. 

Uisce Éireann has reviewed the interaction of the potable water produced at the facilities with the aging network to investigate what can be done to minimise any further sediment dislodgement from the pipes and we are progressing with a conditioning system on the treated water. Detailed design is ongoing and it is expected that full implementation of these works will be completed by early 2025.  

Mains rehabilitation 

Mains rehabilitation works are underway in Cork City, with an investment of approximately half a billion euro required, across several decades, to replace the entire cast iron mains network. 
Watermains replacement works have been completed on Edward Walsh Road and are nearing completion on Popham’s Road. Works on the Cork City South Quays project are progressing ahead of schedule, with works completed at South Terrace and Georges Quay, and currently underway at Sullivans Quay. Further network replacement works are planned for Sydney Park (commencing in July) and Dublin Hill (commencing in September). These works are expected to be completed by year end. Uisce Éireann is working with Cork City Council on a plan for mains rehabilitation for 2025.

Uisce Éireann Taskforce encourages Leesiders to continue to report instances of discolouration

Direct reporting allows issues to be pinpointed and addressed as they arise

Uisce Éireann's dedicated Water Quality Taskforce continues to prioritise the response to water discolouration for affected customers in Cork City. Acknowledging that some people may not be reporting instances of discolouration, the taskforce is urging customers to contact us directly to help manage the response in real time and prioritise works.

Brian O'Leary, Uisce Éireann's Regional Operations Manager for the Southwest, reiterated the focus on public health, stating "protecting public health is the top priority for the taskforce. The water is safe to drink once it is running clear."

"We continue to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. If the issue persists, we encourage customers to contact us directly. The customer care helpline is open 24/7 on 1800 278 278. Each report is actioned, gives us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas."

"As part of Uisce Éireann's continuing commitment to keep the community informed, we met with Cork-based Oireachtas Members and Cork City Councillors in recent weeks to update them on the measures being taken to tackle discolouration and the progress being made by our dedicated taskforce."

Proactive callbacks are ongoing to customers who have previously raised concerns over discoloured water. Customers in Douglas have been contacted regarding their experience since targeting flushing took place in the area, with early indications showing signs of an improvement in water quality. This proactive approach is in addition to regular customer reports received, where a callback is made.

To protect public health, Uisce Éireann has increased its sampling efforts with investigative proactive monitoring at customers' taps. Regular sampling is already carried out at customers' taps and on the network, and operational sampling at the water treatment plant. This provides reassurance that the water is compliant once running clear and assists with investigations into discolouration reports. A number of Cork-based Uisce Éireann employees are also documenting water quality in their homes, with this information helping to better inform us of how the network is performing on a day-to-day basis.

In addition to customer engagement and increased sampling, network improvements are underway and further works are planned to optimise water supply.

Targeted flushing programme 

The proactive intensive mains flushing programme is continuing. Flushing works in the Douglas area are now complete. Flushing commenced in two areas in the Gardiner's Hill/Montenotte and the Gurranabraher/Blarney Street areas on 22 April - the works are expected to take 4 to 6 weeks to complete. The next area to be flushed is being planned based on the numbers of reports of discolouration that have been received. 

The goal of the proactive flushing programme is to address discolouration issues by removing the sediment that has become lodged in the aging cast iron mains. It is anticipated that the 10 worst impacted areas will be flushed by the end of the year, leading to a marked improvement in water quality. This is in addition to standard reactive flushing that takes place based on routine customer reports received. 

The flushing programme is also helping to identify additional watermains works required in these areas. The works identified will be reviewed and scoped once flushing is complete, having regard to prioritisation and available funding. These works should lead to further improvements in water quality.

Mains rehabilitation 

Mains rehabilitation works are underway in Cork City, with an investment of approximately half a billion euro required, across several decades to replace the entire cast iron mains network. 

Watermains replacement works have been completed on Edward Walsh Road and are nearing completion on Popham's Road and South Terrace. George's Quay starts next Monday 20 May. Network improvement works commenced on the South Quays on 19 March, with further network replacement works planned for Sydney Park (commencing in July) and Dublin Hill (commencing in September). These works are expected to be completed by year end. 

Uisce Éireann is working with Cork City Council on a plan for mains rehabilitation for 2025.

Water Treatment Plant

Process Specialists from Uisce Éireann have completed their review of the operational performance of the Lee Road Water Treatment plant, which included investigating additional options to optimise water supply in Cork City. 

The treatment process used at the Lee Road Water Treatment Plant is fully in line with water treatment standards used nationally and globally. More generally, raw water requires continuous optimisation and monitoring as no two raw water sources are exactly the same. To further enhance the water supply in Cork City, we will be looking to introduce new conditioning processes at the treatment plant. It is expected that these measures will be put in place over the next 6 months.

Uisce Éireann prioritising water quality in North side of Cork City with intensive flushing programme rollout

Uisce Éireann continues to work to improve water quality for homes and businesses in Cork City with two targeted programmes for intensive flushing works set to get underway this week in the Montenotte and Gurranabraher areas on the North side of Cork City. These works are scheduled to begin on Wednesday 24 April. 

These targeted flushing works are part of Uisce Éireann's network improvement plan to address water discolouration issues. 

The Montenotte locations extend from Cahergal Park & Lawn to Traction Avenue & Woodlands and from Iona Park to Gardeners Hill including the various locations within such as Merrion Court, Murmont, Saint Joseph's Drive and The Orchards. 

The Gurranabraher locations extend from St. Mary's Avenue off Cathedral Road to Glen Ryan Road to Winter Hill, Blarney Street, Sunday's Well Avenue, Strawberry Hill, The Grove, Monastery Green, St. Joseph's Avenue, Mount Nebo Avenue, Friar Avenue, Boyce's Street, Beech Tree Avenue to Clover Avenue and adjoining areas.

Water Operations Lead for Uisce Éireann, Sean Lynch said: "This is the start of an extensive flushing plan for the North side of Cork City that will be undertaken over the coming weeks. Our goal is to minimise the instances of discolouration for the people of Cork City in targeted areas across Cork City, where reports of discolouration have been received. Areas are prioritised based on customer feedback and reports directly to our customer care team. It is anticipated that this programme of works will take three to four weeks."

The first round of flushing is set to commence 8 pm on Wednesday, 24 April. As works progress through the area, signage will be put in place. Customers are also advised to check the Supply and Service Updates section of the Uisce Eireann website.

The programme involves isolating and flushing small sections of the water network to clear any build-up of sediment from the old cast iron pipes. Isolating the flushing area from the larger network in this manner minimises disruption and improves sediment removal. Clearing the pipes can result in sediment carrying through to customers' taps resulting in increased instances of discoloured water in the short-term. 

To minimise disruption further, the works will be carried out at night-time during off peak usage hours, typically starting after 8pm. It is intended that the network will have time to return to normal before the morning demand starts, reducing the potential for discoloured water at customers' taps.

Each area is broken down into zones for night-time works and as Uisce Éireann progresses flushing through these areas a review of the programme's operational effectiveness will be undertaken before proceeding to the next zone.

Uisce Éireann thanks customers for their patience as we continue to work to reduce instances of discolouration across Cork City, and regrets any inconvenience caused. 

Uisce Éireann continues to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear. If the issue remains unresolved, we encourage customers to contact us directly. The customer care helpline is open 24/7 on 1800 278 278. Customers reporting instances of discolouration help us to determine flushing locations on the network.

Uisce Éireann implements Enhanced Sampling and Flushing Programmes in response to Cork City Water Discolouration

We are continuing our efforts to address water discolouration issues in Cork City. Uisce Éireann's dedicated Water Quality Taskforce is implementing a clear plan which includes increased sampling, targeted flushing programmes and watermains replacement. 

Regular sampling is already carried out at customers' taps and on the network, and operational sampling is carried out at the water treatment plant. With the key focus of protecting public health, Uisce Éireann has increased its sampling efforts, further increasing investigative proactive monitoring at customers' taps. This is to provide continued reassurance that the water is compliant once running clear, and to assist with investigations into discolouration issues. Customers reporting instances of discolouration help us to determine sampling locations in the network. 

To ensure the community is kept informed and supported, proactive callbacks are being made to customers who have previously raised concerns over discoloured water. Uisce Éireann has reached out to approximately 235 customers to date, with the aim of providing updates on ongoing works and gathering further information about customers' experiences. This is in addition to any routine customer reports received, where a callback is made, as per standard procedure. 

Uisce Éireann continues to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear. If the issue remains unresolved, we encourage customers to contact us directly. The customer care helpline is open 24/7 on 1800 278 278. This allows issues to be logged and investigated in a timely manner. Each report is actioned and gives us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas.

In addition to sampling and customer communication efforts, Uisce Éireann is making important network improvements to address water discolouration issues.

The targeted flushing programme works in the Douglas area are nearing completion. The next area to be flushed will cover Iona Park, Murmount, Merrion Court and parts of Gardiner's Hill. These works are scheduled to commence the week beginning 22 April. Plans are also being progressed for flushing in the Blarney Street, Cathedral Road, Gurranabraher and surrounding areas. 

Watermains flushing moves water through pipes at a high flow rate to help remove the build-up of debris and sediment. Clearing the pipes in this manner can result in sediment carrying through to customers' taps resulting in increased instances of discoloured water in the short-term.

This programme expands on previous flushing works and involves installing additional hydrants in some locations to allow the flushing area to be isolated from the larger network, improving the sediment removal and minimising disruption. A review of any additional watermains works required in these areas will be progressed once flushing is complete, having regard to prioritisation and available funding. We are also examining other initiatives which may improve water quality in the network. 

Watermains replacement works have been completed on Edward Walsh Road and are nearing completion on Popham's Road. Network improvement works commenced on the South Quays on 19 March, with further network replacement works planned for Sydney Park and Dublin Hill. Given that approximately 50% of the water network in the city is made up of old cast iron mains, it will take an investment of approximately half a billion euro over several investment cycles to replace the city's network.

Uisce Éireann Taskforce progressing response to water discolouration issues in Cork City

Uisce Éireann's newly established Water Quality Taskforce, dedicated to improving water quality in Cork City, is progressing plans to minimise discolouration with increased sampling set to commence along with enhanced flushing programmes and further mains replacement work. 

The taskforce's priority is to minimise the instances of discolouration for the people of Cork City and ensure they do not exceed the typical frequency expected when operating a water network of this age. Discolouration has existed in Cork City for some time; indeed, it has been a feature of the Cork City network at low levels long before the establishment of Irish Water (now Uisce Éireann).

Increased Sampling: Regular sampling is already carried out at customers' taps, on the network, and at the treatment plant, however, Uisce Éireann is set to further increase investigative proactive monitoring at customers' taps. This is to ensure the water is compliant once running clear, and to assist investigations into any discolouration issues encountered.

Protecting public health is a top priority for Uisce Éireann. The treatment process used by Uisce Éireann at the Lee Road Water Treatment Plant is fully in line with water treatment standards used nationally and globally. Uisce Éireann continue to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear. If the issue remains unresolved, we encourage customers to contact us directly.

Proactive callbacks to customers who have raised concerns over discoloured water in the past are underway with approximately 30 calls a week being made. In certain instances, some of these callbacks have been in-person house calls. The aim of the call is to provide information regarding ongoing actions and to gather additional information as to the customer's experience which will assist in any further investigations required. This is in addition to any recent reports received, where a callback is also made.

Intensified flushing works are underway in the Douglas area. This new programme expands on previous flushing in the area and involves installing additional hydrants in some locations to make the flushing area smaller and isolated from the larger network; thus, improving the sediment removal. The works are also being carried out at night-time, during off peak usage hours, to allow the network time to return to normal before the morning demand starts, again reducing the potential for discoloured water at customers' taps. Initial reviews undertaken are showing positive signs, with Uisce Éireann set to target a new section of Douglas from today, Monday, 11th March: Rathmore Lawn, Cross Douglas Road, Douglas Road, Loreta Park, Rosebank, Ashdale Park, Ballincurrig Park, Cherry Drive, Whitehorn, Baltimore Lawn, Knockrea Park, Greenhills Court, Glencurrig, Ashdene, Alderwood and surrounding areas. 

Water mains replacement works have been completed on Edward Walsh Road and are nearing completion on Popham's Road. A third project is soon to commence on the South Quays. In the second half of this year, works are also planned for Sydney Park and Dublin Hill.

A water network is a delicate ecosystem in its own right, and replacing watermains is not a straightforward process. It requires liaising with multiple stakeholders, planning, permissions, road closures, road reinstatements etc. Areas that are worst impacted by leakage and discolouration are prioritised. Given that approximately 50% of the water network in the city is old cast iron mains, it will take an investment of approximately half a billion euro over several investment cycles to replace the city's network.

Process Specialists from Uisce Éireann are continuing to review the operational performance of the Lee Road Water Treatment plant, investigating additional options to further improve water services in Cork City.

Uisce Éireann provides high-quality, clean, safe drinking water to over 125,000 people in Cork City every day. In 2023 we received just over 1600 calls to our customer care team regarding discolouration in Cork City. This represents just over 1% of customers. Recognising that some people may not be reporting incidents, we would encourage customers to contact us directly on the Uisce Éireann customer care helpline, open 24/7 on 1800 278 278. This allows issues to be logged and investigated in a timely manner and provides us with accurate and real time information. Each reported issue is actioned and gives us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas.

Extensive flushing works to take place in the Douglas area

Uisce Éireann continues to work to improve water quality and supply for homes and businesses in Cork City with a further programme of flushing works set to get underway next week in the Douglas area. It is anticipated that the entire programme of works will take approximately two to three weeks. 

 Flushing involves isolating small sections of the water network to clear any sediment from the old cast iron pipes to reduce instances of discolouration. Clearing the pipes in this manner can result in sediment carrying through to customers' taps resulting in increased instances of discoloured water in the short-term. 

The flushing works in Douglas are one of the recommendations put forward by the Cork City discolouration taskforce. This new programme expands on previous flushing in the area, part of which includes enabling works which involves installing additional hydrants in some locations prior to flushing, thus improving the sediment removal. The works will also be carried out at night-time during off peak usage hours, typically starting after 8pm. It is intended that the network will have time to return to normal before the morning demand starts, again reducing the potential for discoloured water at customers' taps.

As Uisce Éireann progresses flushing throughout the Douglas area, which has been broken down into 12 zones, a review of the programme's operational effectiveness will be undertaken before proceeding to the next zone.

The first round of flushing is set to commence 8 pm on Monday, 4th March. As works progress through the Douglas area, signage will be put in place. Customers are also advised to check the Supply and Services section of the Uisce Eireann website on our website.

Uisce Éireann thanks customers for their patience as we continue to work to reduce instances of discolouration across Cork City, and regrets any inconvenience caused. 

Protecting public health is a top priority for Uisce Éireann. Ongoing testing and analysis of the water supply continues, in conjunction with extensive monitoring across the city's water network to ensure the water is compliant with drinking water regulations and is safe to drink. The results of these ongoing tests are shared with the Environmental Protection Agency (EPA) and the Health Service Executive (HSE).

Water Operations Lead for Uisce Éireann, Sean Lynch said:

"This is the start of an extensive flushing plan for the Douglas area that will be undertaken over the next few weeks. Our goal is to minimise the instances of discolouration for the people of Cork City. Discolouration has existed in Cork City for some time and has been a feature of the Cork City network at low levels long before the establishment of Irish Water (now Uisce Éireann). We acknowledge that the frequency of discolouration reports has increased over the past 18 months, and this is not meeting the standard that customers expect. This can be attributed to a number of factors including the continued upgrading and investment in plants and pipework across the city and most recently an increase in leaks caused by bursts due to freezing weather. Given that approximately 50% of the water network in the city is old cast iron mains, it will take an investment of approximately half a billion euro over several investment cycles to replace the city's network."

Areas potentially impacted with this round of flushing include Half Moon Lane, Westview, Kilcolman Lawn, Palaceanne Lawn, Palaceanne Court, Hawthorn Villas, Glen View, Woodlawn, Heatherton, Greenhills Estate, Cross Douglas Road, Douglas Road and surrounding areas. Other adjoining areas in Douglas may potentially be impacted.

In the short term, Uisce Éireann continues with works to proactively and reactively flush the network in targeted areas across Cork City where reports of discolouration have been received. Areas are prioritised based on customer feedback and reports received by our customer care team.   

Uisce Éireann advises customers not to drink discoloured water. In the event of discolouration, running the tap for several minutes, we recommend up to 20 minutes, will usually restore water to a clear colour - the water is safe to drink once running clear. For more information and advice, please visit our Discoloured Water page. 

If the issue remains unresolved, we encourage customers to contact us directly on the Uisce Éireann customer care helpline, open 24/7, on 1800 278 278.

Planned flushing works to take place in the Douglas area

Uisce Éireann continues to work to improve water quality and supply for homes and businesses in Cork City with a further programme of flushing works set to get underway tomorrow. 

To address increased reports of discolouration in the Douglas area, an intense network flushing programme will be undertaken over two days on Thursday February 29th and Friday March 1st. 

Flushing involves isolating small sections of the water network to clear any sediment from the old cast iron pipes to reduce instances of discolouration. Clearing the pipes in this manner can result in sediment carrying through to customers' taps resulting in increased instances of discoloured water in the short-term. Areas potentially impacted with this round of flushing include Half Moon Lane, Westview, Kilcolman Lawn, Palaceanne Lawn, Palaceanne Court, Hawthorn Villas, Glen View, Woodlawn and surrounding areas.

Uisce Éireann taskforce prioritises response to water discolouration issues in Cork

Utility reiterates its call to report incidences of discolouration so that expert team can pinpoint and address issues directly with customers as they arise.

Uisce Éireann has established a taskforce in Cork City, dedicated to improving water quality. Acknowledging that water services in Cork City are not meeting the standards that customers rightly expect, Uisce Éireann is assuring the public that it continues to treat the matter with the utmost urgency, including following up with proactive callbacks to customers who have raised concerns over discoloured water.

The organisation recognises that, although the ongoing issues are having a significant impact on affected communities, it provides high-quality, clean and safe drinking water to over 125,000 people in Cork City every day, and based on 2023 reports to our call centre, it is estimated that discolouration affects just over 1% of customers. Recognising that some people may not be reporting incidents, Uisce Éireann is reiterating its call for customers to contact them directly. Each call is investigated and actioned.

Uisce Éireann has invested more than €100 million in infrastructure improvements across a number of projects in recent years including the Lee Road Water Treatment Plant. These improvement works, including increased flood protection and a link to an additional back up supply from Iniscarra, have significantly modernised and improved the overall water supply infrastructure in the city, benefiting homes and businesses. 

In general, issues such as discolouration can occur when dealing with an aged network such as Cork City's. There are approximately 600km of watermains in Cork City, which is enough pipeline to bring you from Douglas to the Giant's Causeway in Co Antrim. 50% to 60% of these watermains are made from cast iron and approximately 100 years old, dating back to the 1920s. It would take an investment of approximately half a billion euro over several investment cycles to replace these. Due to the age and deteriorating condition of the pipes, they are prone to bursts and leakage. In old cast iron mains, sediment can become dislodged during repair or upgrade works and can occasionally be carried through to customers' taps, leading to the water appearing brown or orange. 

Brian O'Leary, Uisce Éireann's Regional Operations Manager for the South West, reassured the people of Cork City that the water is safe to drink once it is running clear.

"Protecting public health is a top priority for Uisce Éireann. The treatment process used by Uisce Éireann at the Lee Road Water Treatment Plant is fully in line with water treatment standards used nationally and globally. Water services engineers and drinking water compliance specialists continue to closely monitor the water treatment plant, reservoirs and the water network that supply the city to ensure compliance with drinking water regulations."

"We continue to advise not to drink discoloured water. In the event of discolouration, running the tap for several minutes - we recommend up to 20 minutes - will usually restore water to a clear colour. The water is safe to drink once running clear. If the issue remains unresolved, we encourage customers to contact us directly."

"Uisce Éireann provides high-quality, clean, safe drinking water to over 125,000 people in Cork City every day. In 2023 we received just over 1600 calls to our customer care team regarding discolouration in Cork City. This represents just over 1% of customers.

This allows issues to be logged and investigated in a timely manner and provides us with accurate and real time information. Each reported issue is actioned and gives us a better understanding of any ongoing issues and allows us to prioritise the worst impacted areas."

The Uisce Éireann leakage reduction team have also been hard at work reducing the amount of water lost by 50%, amounting to a staggering 17 million litres, across the city every day. Uisce Éireann remains committed to ongoing large-scale investment and to the delivery of world class water services for the people of Cork City.

Remedial actions currently in place include:

Sampling

Testing and analysis of the water supply, in conjunction with extensive monitoring across the city's water network to ensure the water is compliant with drinking water regulations and is safe to drink once it runs clear.

Flushing

Flushing involves isolating small sections of the network and clearing the watermains of any sediment from old cast iron pipes to reduce instances of discolouration.

Operational adjustments

We have carried out operational adjustments to pumping and water storage levels to reduce discolouration.

Process Optimisation

Uisce Éireann Process Specialists are continuing to review the operational performance of the New Lee Road Water Treatment plant, investigating additional options to further improve water services in Cork City.

Water mains replacement          

A water network is a delicate ecosystem in its own right, and replacing watermains is not a straightforward process. It requires liaising with multiple stakeholders, planning, permissions, road closures, road reinstatements etc. Areas that are worst impacted by leakage and discolouration are prioritised.

Uisce Éireann continues to engage extensively with customers and elected representatives, including attending Cork City Council's Environment, Water & Amenity Strategic Policy Committee on 16th January 2024. Uisce Éireann also invited Oireachtas members from Cork City to a briefing on 24th November 2023. 

Uisce Éireann has also commenced proactive callbacks to customers who have raised concerns over discoloured water. In certain instances, some of these callbacks have been in-person house calls. The aim of the call is to provide information regarding ongoing actions and to gather additional information as to the customer's experience. 

More information on ongoing work in Cork City, including information on how to log an issue is available on our website.

Uisce Éireann continues to work to improve water quality and supply for homes and businesses in Cork City with a further programme of flushing works set to get underway tomorrow. 

From tomorrow, Wednesday 29 November, network flushing will be undertaken for approximately two weeks and will work through Corrib Lawn, Boyne Crescent, Ballinderry Park, Annalee Grove, Gweendore Avenue, Glencree Crescent, Liffey Park, Shannon Lawn, Lagan Grove, Murmount Court, Murmount Grove, Avonmore Park, Glenamoy Lawn, Spring Vale and Old Youghal Road and surrounding areas. 

Flushing works initially result in increased discolouration locally as the water is used to remove sediment from the network at hydrants. The flushing time required for the water to run clear is dependent on the local network conditions. 

The flushing work that we have undertaken on the network is a key part of our action plan to address intermittent discolouration issues impacting a number of customers in Cork City. 

Water services engineers and drinking water compliance specialists continue to closely monitor reservoirs that supply the city and have made operational adjustments which have reduced instances of discolouration. 

We know from previous years that the changes in seasons and weather can be challenging in terms of managing water quality in Cork City. Sub-zero temperatures inevitably leads to more bursts, repairs and maintenance that will result in increased instances of discolouration in the network. 

Uisce Éireann thanks customers for their patience as we work to reduce instances of discolouration across Cork City, and regret any inconvenience caused. Ongoing testing and analysis of the water supply continues, in conjunction with extensive monitoring across the city's water network to ensure the water is compliant with drinking water regulations and is safe to drink. The results of these ongoing tests are shared with the Environmental Protection Agency (EPA) and the Health Service Executive (HSE).

Uisce Éireann and Cork City Council wish to advise customers in the Ardcullen and surrounding areas that reactive flushing works are being carried out on the water network this evening.

As a result of a pump failure in the area this morning, there may be an increase in discoloured water at customers taps over the next 24 hours. If this occurs, running the tap for several minutes will usually restore water to a clear colour. Uisce Éireann continues to advise customers not to drink discoloured water.

Recent issues most likely linked to commissioning of a new pumping setup for filling reservoirs

Uisce Éireann acknowledges the impact of ongoing discolouration issues for customers in parts of Cork City and we are prioritising works at the moment to address these. 

The water leaving the treatment plant is rigorously tested to ensure it complies with the drinking water standards, and that the water is safe to drink once running clear. The treatment process used by Uisce Éireann is fully in line with water treatment standards around the country and across the world.

There has been no recent change to the process for treating the water at the Lee Road Water Treatment Plant. The recent spike in discolouration issues is most likely linked to the commissioning of a new pumping setup for filling the reservoirs. Increased flows resulted in some sediment becoming dislodged from the pipes supplying the reservoirs, which have led to the discolouration issues in the network. To address this, adjustments have been made to the pumping rates to prevent the dislodging of any further sediment from the pipes supplying the reservoirs.

In addition, Uisce Éireann crews are carrying out planned network flushing, which involves systematically flushing section by section of the network and clearing the watermains of any sediment from old cast iron pipes. While these works are carried out customers in some areas may continue to experience intermittent discolouration. However we expect that as a result of these actions, overall incidents of discolouration should decrease.

All customer complaints are logged and we would encourage the public to continue to report any discolouration issues to Uisce Éireann so that we can identify and resolve these issues throughout the network.

Customers can visit the Uisce Éireann website, www.water.ie, for details of flushing times and locations and to look out for flushing signs in your area when flushing is ongoing. 

Brian O'Leary, Uisce Éireann's Regional Operations Manager, said: "We acknowledge there have been an increase in discolouration complaints and apologise for any inconvenience to customers as a result. The Cork City Water Quality Working Group, with expert representatives and engineers from Uisce Éireann and Cork City Council, continues to meet regularly and monitor the situation with flushing of the network being carried out in prioritised areas of the city. Areas are prioritised based on customer feedback and reports received by our customer care team."

"Flushing was carried out for over 3 weeks in the Mayfield area in October and November. Flushing is currently ongoing in Farranree and Gurranabraher in response to customer reported issues. Once complete, flushing will continue into other areas based on the reported issues. Customers will see increased discoloration while flushing is ongoing as the sediment is be cleared from the pipework. We would ask that customers get in touch with us at 1800 278 278 to report discolouration issue so that we can investigation and address them." 

To improve water supply in Cork City, Uisce Éireann has invested in excess of €100 million in infrastructure improvement across a number of projects including the Cork City Water Supply Scheme, which is nearing completion, the replacement of the Churchfield Reservoir roof, the upgrade of Glashaboy Water Treatment Plant, and the new Lee Road Water Treatment Plant.  

These works have significantly modernised and improved the overall water supply infrastructure in the city, ensuring a safe, secure and reliable water supply to homes and businesses. 

The Uisce Éireann customer care helpline is open 24/7 on 1800 278 278 or via Twitter @IWCare. 

Uisce Éireann continues to advise customers not to drink discoloured water. Please see our Discoloured Water page.

Uisce Éireann continues to work to improve water quality and supply for homes and businesses in Cork City with a further programme of flushing works set to get underway tomorrow.

From tomorrow, Wednesday 18 October, network flushing will be undertaken for approximately two weeks and will work through Old Youghal Road, Murmount, Montenotte, Merrion Court and surrounding areas. The flushing works that we have undertaken on the network is a key part of our action plan to address intermittent discolouration issues impacting a small number of customers in Cork City.

Water services engineers and drinking water compliance specialists continue to closely monitor reservoirs that supply the city and have made operational adjustments which have reduced instances of discolouration. In addition to this, we know from previous years that the changes in seasons and weather can be challenging in terms of managing water quality in Cork and can impact the raw water source requiring adjustments to the treatment process, which is a standard practice.  If network improvement works increase, or when we have weather events, sub-zero temperatures causing more bursts, we will see a slight increase in instances of discolouration again.

Uisce Éireann thanks customers for their patience as we work to reduce instances of discoloration across Cork City, and regret any inconvenience caused. Ongoing testing and analysis of the water supply continues, in conjunction with extensive monitoring across the city's water network to ensure the water is compliant with drinking water regulations and is safe to drink. The results of these ongoing tests are shared with the Environmental Protection Agency (EPA) and the Health Service Executive (HSE).

In general, issues such as discolouration, bursts and leakage are unfortunately commonplace when dealing with an aged network such as Cork City's. This is a national issue and there is no easy solution. There are approximately 600km of watermains in Cork City, 60% to 70% of which are made from cast iron and approximately 100 years old, dating back to the 1920s. Due to the age and deteriorating condition of the pipes, they are prone to bursts and leakage. In old cast iron mains, sediment can become dislodged during repair or upgrade works and can occasionally be carried through to customers' taps, leading to the water to appear brown or orange.

In the short term, Uisce Éireann continues with works to proactively flush the network in targeted areas across Cork City where reports of discolouration have been received. Areas are prioritised based on customer feedback and reports received by our customer care team. To date, six phases of planned network flushing have been undertaken to reduce instances of discolouration impacting customers' water supply. This involves isolating small sections of the network and flushing them of any dislodged sediment.

In recent weeks, based on reports of discolouration, flushing has been carried at the out in the following areas: Cathedral Road, Baker Road, Churchfield Avenue, Blarney Street, Strawberry Hill, Mount Saint Joseph's Drive, Sundays Well Avenue, Gurranabraher, Saint Anthonys Road and Boyce Street. The Cork City Water Quality Working Group, with expert representatives and engineers from Uisce Éireann and Cork City Council, continue to meet regularly and monitor the situation.

Uisce Éireann continues to invest in the water infrastructure across Cork with a number of multi-million-euro projects underway to provide a safe, secure and reliable water supply to homes and businesses.

Customers experiencing water quality issues are advised to contact the Uisce Éireann Customer Care helpline, open 24/7 on 1800 278 278 or via X (formerly Twitter) @IWCare, so the issue can be logged and investigated. Each complaint is actioned and gives us a better understanding of any ongoing issues.

Uisce Éireann and Cork City Council wish to advise customers on Quaker Road, Summerhill South, Parkowen, High Street, Southern Coad, Capwell Road, Capwell Avenue and surrounding areas that scheduled maintenance works will be carried out on the water network starting this Sunday to improve water quality.

From Sunday 13 August until Wednesday 23 August approximately, Uisce Éireann and Cork City Council will commence network flushing works. This involves isolating small sections of the network and clearing the watermains of any sediment from these old cast iron pipes to reduce instances of discolouration of the water supply. 

Speaking about the maintenance works, Operations Lead with Uisce Éireann, Pat Britton said: 

"The flushing works that we have undertaken on the network in recent months is a key part of our action plan to address increased but intermittent discolouration issues impacting a small number of customers in Cork City. Currently, the number of complaints in relation to this issue continues to be low. However, as Cork City's water distribution network is very old and very large, occasionally issues such as discolouration will occur but we will continue to work hard to limit these instances for customers as much as possible." 

There are approximately 600km of watermains across Cork city, 60% to 70% of which are made from cast iron and up to 100 years old. The aging network combined with essential upgrades and maintenance works, unplanned outages and bursts, and the commissioning of new infrastructure can cause issues such intermittent discolouration for customers.

During the works, customers may experience some temporary discolouration or their water to appear brown or orange as the sediment is flushed from the network. If this occurs, running the tap for several minutes will usually restore water to a clear colour. Uisce Éireann continues to advise customers not to drink discoloured water.

Ongoing testing and analysis of the water supply continues, in conjunction with extensive monitoring across Cork City's distribution network. This ensures the water is compliant with drinking water regulations and is safe to drink. The results of these ongoing tests are shared with the EPA and the HSE.

Uisce Éireann and Cork City Council wish to advise customers on Blarney Street, Cathedral Road, The Grove, Strawberry Hill, Mount Saint Joseph's Drive, The Rise, Sundays Well Avenue, Gurranabraher, Saint Anthony's Road, Boyce Street and the surrounding areas that scheduled maintenance works will be taking place on the water network. 

There are approximately 600km of watermains in Cork city, 60%-70% of which are made from cast iron and up to 100 years old. This, combined with improvement works across the city, unplanned outages or bursts, and new infrastructure being brought online, is adding to issues normally associated with an ageing network, such as discolouration, for a small number of customers. 

From Monday, 19 June, for approximately two weeks until the 30 June, Uisce Éireann and Cork City Council will commence flushing works which involves isolating small sections of the network and clearing the watermains of any sediment from these old cast iron pipes to reduce instances of discolouration of the water supply. 

Speaking about the maintenance works, Operations Lead with Uisce Éireann, Pat Britton said: 

"This is the fourth round of flushing that we have undertaken in recent months, as part of our action plan to address the increased intermittent discolouration issues. At the moment, discolouration complaint volumes are low, and have been for a number of months. However, when dealing with an old and vast water network like we have in Cork City, there are always going to be a small number of incidences of discolouration." 

With the clearing of sediment as part of the flushing works there may be a temporary discolouration of the water supply in the area. In the event of discolouration, running the tap for several minutes will usually restore water to a clear colour. Uisce Éireann continues to advise customers not to drink discoloured water.

Uisce Éireann is responsible for the delivery of all public water and wastewater services in Ireland. We are committed to continuously upgrading and developing critical infrastructure to support the growth needed in housing and across our economy, while protecting the environment and safeguarding water supplies.

Uisce Éireann, in partnership with Cork City Council, is progressing with works to manage intermittent discolouration issues impacting the water supply in some areas of Cork City. 

There is approximately 600km of watermains in Cork City, 60%-70% of which is made from cast iron and is up to 100 years old, dating back to the 1920s. Due to the age and deteriorating condition of the pipes, they are prone to bursts and leaks, resulting in low pressure, water outages and discolouration. Old cast iron mains also typically suffer from sediment becoming dislodged during repair or maintenance works, which can travel to customers' taps causing the water to appear brown or orange in colour. Uisce Éireann is investing in infrastructure improvement works in the region across a number of multi-million euro projects. The scale of improvement works can also be a contributing factor in sediment becoming dislodged, leading to temporary discolouration of the water supply.

Uisce Éireann is treating this matter with the utmost priority. A safe and secure water supply for Cork City is a top priority for Uisce Éireann and we have set up a working group with representatives from across the business, in partnership with Cork City Council Water Services, to address this issue. While sampling and monitoring of the water supply has been ongoing, it will now be intensified in affected areas across the network to gain a greater understanding and further safeguard customers, ensuring water continues to be compliant with drinking water regulations and remains safe to drink. Should any instances of non-compliance be found, the results are shared with the EPA and the HSE. Flushing used to clear networks of sediment or discolouration is planned for key areas of the network and is currently underway in the Douglas area. Uisce Éireann will continue to flush areas identified as being problematic for discolouration.  

Operations Lead for Uisce Éireann Pat Britton said: "I would like to thank customers for their patience as we work hard to address the intermittent discolouration issues in Cork City. Safeguarding the water supply and protecting public health is a top priority for Uisce Éireann and we would like to reassure customers that the water supply serving the city is safe to drink. The upgrade works ongoing are the largest ever undertaken in the city and will provide a safer and more reliable water supply for generations to come."

In the event of discolouration, usually running the tap for several minutes will restore water to a clear colour. Uisce Éireann continues to advise customers not to drink discoloured water. Each and every complaint is fully investigated. Customers with queries or concerns about the quality of their drinking water should contact the Uisce Éireann customer care helpline, open 24/7 on 1800 278 278 or via Twitter @IWCare.

Uisce Éireann, in partnership with Cork City Council, is progressing works to manage intermittent discoloration issues impacting the water supply in some areas of Cork City. 

Ongoing testing and analysis of the water supply continues in conjunction with extensive monitoring across the city's distribution network ensuring the water is compliant with drinking water regulations and is safe to drink. The results of these tests have been shared with the EPA and the HSE. 

In Ireland, drinking water can pass through several kilometres of pipework before it reaches homes and businesses. Some of this pipework is constructed from cast iron and, depending on the area, can be up to 100 years old. Old cast iron mains typically suffer from sediment being dislodged during repair or maintenance works, causing temporary discolouration of the water or the water appearing brown before it reaches customers' taps. With the change in weather conditions recently, there has been an increase in bursts and outages which has slightly exacerbated the issue of discoloured water in Cork city. Usually running the tap for several minutes will restore the clear colour. Uisce Éireann advises customers not to drink discoloured water until it clears.

Most of the time, drinking water passes over this sediment unchanged. However, changes in flow, pressure or direction can dislodge this sediment and carry it through to your tap. This can cause your water to appear brown or orange and is more likely to occur when repair or maintenance works are being carried out on public water mains.

Operations Lead for Uisce Éireann, Niall O'Riordan said: "Safeguarding the water supply in Cork city and protecting public health is a top priority for Uisce Éireann and we would like to reassure customers that the water supply serving Cork city is safe to drink. We understand the concerns raised by some customers concerning the colour of their drinking water and acknowledge the disruption and inconvenience caused as we continue to upgrade and improve the water supply. As a precaution, we have increased testing on the water supply and are keeping the situation under close review."

"Extensive upgrade and improvement works to the water supply continue across Cork city, all of which can result in some short-term discoloration. It is not ideal, but it is a common occurrence throughout the country, particularly for us in Cork city as parts of the network are over 100 years old." 

"I would like to thank customers who have been impacted by the discolouration issues and appreciate your patience as we work hard to ensure a continued high standard of water quality in Cork city."

Last month, Uisce Éireann and Cork City Council became aware of an increase in reports of discoloured water in some areas of Cork City.

Investigations were carried out at the time in the affected areas to identify the source of these water issues and remedial actions were carried out. The investigations found that following a recent upgrade of infrastructure in Cork city, where a number of new treatment systems are being brought online, that water being produced was impacting on some of the older pipes in the network, thus causing sediment to come loose and cause a discolouration of the water being supplied to customers. We are actively working to adapt the process to ensure that the sediment does not break down and cause the discolouration.

The issue is being continuously monitored, however, approximately two weeks ago, there was an increase in reports of discoloration in the network. Further remedial work and alterations were carried out on Friday, 16th of September and this has already shown an improvement to the water supply. Some customers may still experience discolouration periodically but we anticipate this improvement to continue over the coming days as the changes embed in the network.

Water leaving Uisce Éireann's treatment plants is continuously tested to ensure it meets all drinking water standards. Water is also regularly tested at customer delivery points to ensure the highest standards are met.
