Mayo Water Treatment Plant To Undergo Major Upgrades

Lough Mask Water Treatment Plant (WTP) in County Mayo is set to undergo major upgrades.

Veolia Water Ireland will carry out work on behalf of Irish Water and Mayo County Council to increase the plant's capacity, facilitating development across Mayo, Galway and Roscommon.

Work will include an upgrade of both the treatment processes and the capacity at Lough Mask WTP, the region's biggest treatment plant which treats water for towns and villages in Mayo as well as those in North West Roscommon and North Galway.

Speaking about the works, Martin Temple, Capital Programme Regional Lead with Irish Water, said: "We are looking forward to delivering this important project on behalf of the communities in Mayo, Roscommon and Galway. These works will enable the expansion of a reliable water supply and provide a platform for social and economic development of those areas well into the future.


"A project of this nature underpins the importance of having one national utility for the provision of water and wastewater services. County borders are not an obstacle with one plant in Mayo serving customers in three counties. Irish Water would like to thank their water services colleagues in Galway, Roscommon and Mayo County Councils for their co-operation on these strategically important projects."

This latest €9 million investment comes after an extension of the supply to both Ballinlough/Loughglynn and Williamstown in 2018. That €10m investment ensured a clean and secure supply for 5,000 customers and resulted in the removal of the longstanding boil notice in Ballinlough affecting 3,600 people.

Explaining this latest investment, Senior Executive Engineer with Mayo County Council, Kieran Shally added: "By improving facilities and capacity of the water treatment plant we are ensuring a safe and reliable water supply for Mayo, North West Roscommon and North Galway and its surrounding areas as well as enabling those areas to thrive both socially and economically in the years to come.

"Preliminary works are underway with the main plant upgrade due to start in the second half of 2022 and continue for approximately 18-20months."
