Water Supply

Fingal is fortunate to be self sufficient in terms of water supply. The Council runs two water treatment plants. The primary source of Fingal’s water is the Leixlip Treatment plant on the River Liffey. This plant provides a guaranteed output of 148 megalitres per day, although it can produce up to 168 megalitres for short periods. This equates to the daily production of enough potable water to fill 60 Olympic sized swimming pools! Of the water produced by Fingal only a half is used within the county, the rest being exported to Dublin City,South Dublin, Kildare and Meath. The other treatment plant is the recently completed Bog of the Ring plant, which produces 4 megalitres a day. This plant extracts groundwater from wells and supplements the water supply of the northern part of the County. Some parts of the county that border on the City are supplied by feeds from within Dublin City, whose water originates from Ballymore Eustace and Roundwood. The water produced by Fingal regularly meets the required EU Drinking Water quality parameters.


The treated water is distributed throughout Fingal using a combination of pumped mains, gravity mains and reservoirs. At present, Fingal has approximately 1570 km of water mains. The majority of the water is pumped from Leixlip up twin rising mains to the main storage reservoir at Ballycoolen. The water then gravitates through pipes from this reservoir to Blanchardstown and the East Coast Areas. There are some localised high areas within Fingal that require pumping to ensure an adequate water supply. These include Kilshane to Garristown, Hollywood, Palmerstown and Howth. There are major and minor reservoirs spread throughtout the County to give back up storage and satisfy the peaks and troughs of daily demand.

 

Leixlip Water Treatment Plant Expansion - Phase 5

Leixlip Water Treatment Plant is the second largest water treatment plant in Ireland and supplies drinking water to the Greater Dublin Region including Fingal, South Dublin, Dublin City and areas of Kildare and Meath. The plant requires further expansion to cater for the rapidly growing water demands of the region.
