Water supplied from Ballymore Eustace Water Treatment plant remains safe to drink

Information below is relevant until further updates are provided here or on our Supply and Service Updates section.

The raw water supply to Ballymore Eustace Water Treatment Plant  is taken from Poulaphouca Reservoir (Blessington Lake), and is monitored continuously via 24/7  instrumentation, a laboratory sampling program and visual inspections of the reservoir. Further quality analysis and checks take place through each step of the treatment process and in the distribution network to ensure the water supplied to customers is safe to drink. Algae blooms do periodically occur for a variety of reasons, but do not typically impact the treatment process at Ballymore Eustace Water Treatment Plant.
