Source of Water in Dublin, Ireland

The primary source of tap water supply for the Dublin Region is surface water. Water is abstracted from Poulaphuca lake and treated in Ballymore Eustace Water Treatment Plant. Treated water is then transmitted from Ballymore Eustace to Dublin. Of the water treatment plants, water runs by gravity into large pipes to service reservoirs. These give short-term storage to guarantee a constant water supply throughout peak demand periods. Levels in the reservoirs drop during the day when demand is high and rise by night during demand is low.

From the service reservoirs, water flows through a smaller pipe system (distribution mains) to the City’s homes, schools, and businesses. Most water flows by gravity. However, in some elevated areas, it is necessary to pump. Over two thousand kilometers of underground pipes carry the water in a web-like network through the City.

Another source of water comes from groundwater. ​​​​Groundwater is vital as a source of drinking water, and it supports river flows, lake levels, and ecosystems. It contains natural substances dissolved from the soils and rocks. Human actions on the land surface can cause contamination. As a clean but vulnerable resource, groundwater needs to be managed and protected.
