Dundalk Water Main Replacement - Hill Street

National Leakage Reduction Programme

Irish Water, in partnership with Louth County Council, is replacing ageing water mains in Dundalk, Co. Louth to improve security of supply, improve water quality and reduce high levels of leakage.

The project to replace an ageing section of water mains in Hill Street, Dundalk which recently commenced are being carried out as part of Irish Water’s National Leakage Reduction Programme. The works involve the replacement of approximately 150 meters of old cast iron water mains with high density polyethylene (plastic) pipes.

The works will also involve laying new water service connections from the public water main in the road to customers’ property boundaries and connecting it to the customers’ water supply. Where the existing service connections on the public side are lead these will be replaced as part of this improvement work.

The works will be carried out on behalf of Irish Water by GMC Utilities Ltd and are expected to be completed by mid August 2018.
