Drinking water is a scarce commodity essential to the City and the health of its citizens. Every day 540 million litres of high quality drinking water is produced and supplied to 1.5 million customers in the Dublin Region.

Water is collected from the Dublin and Wicklow mountains for treatment at the four water treatment plants at Ballymore Eustace, Roundwood, Ballyboden and Leixlip.

It is then distributed to customers in Dublin City and in the South Dublin, Dun Laoghaire Rathdown, Fingal, Kildare and Wicklow County Council areas through a network of service reservoirs and over 7,000 km of pipes.

Water is a precious resource and should be used sparingly. Information about saving water can be found online at

Bogus Callers

On occasion it may be necessary to carry out water quality monitoring or repair and maintenance work at your property. This may require our employees to gain access to your property. Unfortunately bogus callers can sometimes call to your property claiming to be from Dublin City Council’s Water Services. Find out how to identify bogus callers

Reservoir safety

On hot days, a dip in a reservoir may appear like a great way to cool down. The still water may seem harmless, but it's actually a dangerous killer which can claim a life in minutes! It doesn't matter how strong a swimmer you are, swimming in reservoirs is extremely dangerous. Find out more on reservoir safety
