Liscarton Water Treatment Plant

Water Project

Irish Water is investing approximately €9 million in Navan’s Water Supply to upgrade its Water Treatment Plant at Liscarton.

Irish Water in partnership with Meath County Council, is investing €9m to upgrade the water treatment plant (WTP) at Liscarton. We recently awarded a contract to Veolia Water Ireland to carry out the works as part of this project. Works are due to commence in the coming weeks and will take approximately 12 months to complete.

Liscarton WTP treats and supplies water to Navan. Liscarton WTP was originally constructed in 1977 and supplies over 40,000 people across Navan. The Navan Water Supply is on the Environmental Project Agency’s (EPA’s) Remedial Action List (RAL).
