Residents in the Greencastle area of County Donegal have welcomed a new and improved water supply.

Irish Water invested almost €6 million to upgrade the supply, bringing a better quality of water from the Eddie Fullerton Pollan Dam to the people of Greencastle.

The Greencastle supply is currently on the Environmental Protection Agency's (EPA's) Remedial Action List (RAL) for elevated levels of trihalomethanes (THMs). The Greencastle water treatment plant will be decommissioned and water from the Eddie Fullerton Pollan Dam will be treated at the Illies Water Treatment Plant before being delivered into the network supplying Greencastle and East Inishowen.

Explaining more about the project, Irish Water's Diane Carroll said: "The upgraded water supply scheme will safeguard the water supply to homes and businesses currently served by the existing Greencastle Water Treatment Plant. The supply from this plant will be replaced by the supply from the East Inishowen Regional Water Supply Scheme (RWSS). This has been enabled by an extension of the Pollan RWSS to East Inishowen, allowing the East Inishowen RWSS to now supply Greencastle. 

"The scope of works completed included the laying of over 10km of new water main, the construction of a new reservoir and associated booster station. This transfer of supply from the Greencastle Water Treatment plant to the Illies Water Treatment Plant will provide a more robust treatment system."

This project forms part of Irish Water's investment plan which looks to address the most critical issues outlined in the utility's Business Plan.
