Managing our Water Supplies

Printer-friendly version

Water is supplied in Dublin on a Regional basis. The Region includes all of Dublin City and County and parts of Wicklow and Kildare. On a typical day 540 million litres of water is collected from our rivers, cleaned and made safe to drink at four main treatment plants. Three of these treatment plants are operated by Dublin City Council on behalf of Irish Water at Ballymore Eustace (Liffey), Roundwood (Vartry) and Ballyboden (Dodder). Fingal County Council operates the treatment plant at Leixlip (Liffey) on behalf of Irish Water.

Once water is treated it has to be delivered to the Region’s 1.5 million customers through a series of service reservoirs and a network of 7,200km of underground pipes, of which over 2,400km are in the City. Most of our water is gravity fed however in some elevated areas pumping is required.
