Drinking Water

Drinking Water Quality Monitoring Results:

Summary results of samples of drinking water taken throughout the network during 2011 can be found in the documents section below.

Samples of drinking water are taken throughout the network and analysed for over 50 parameters. Analysis is carried out on all samples taken in South Dublin at Dublin City Council's central laboratory. A description of the various parameters is given on Dublin City Council's Website - What are the drinking water quality standards

Results of sampling carried out in 2017 are as follows:

Results for March 2017
Total number of tests performed: 324
Total number of non-compliant results: 0
Overall percentage compliance: 100%

Results for February 2017
Total number of tests performed: 324
Total number of non-compliant results: 0
Overall percentage compliance: 100%

Results for January 2017
Total number of tests performed: 372
Total number of non-compliant results: 0
Overall percentage compliance: 100%

Water Hardness

Water Hardness enquiries usually relate to installation of new dishwashers and washing machines. The water in South Dublin County Council is mainly sourced from two water treatment plants at Ballymore-Eustace and Leixlip. The water from Leixlip would be considered hard water and from Ballymore-Eustace it is soft water. We don’t supply any water directly from Leixlip, but water from Leixlip is blended in our reservoir at Peamount which serves parts of Lucan and hence water in this area can be of medium hardness.

Typical values for total hardness as Calcium Carbonate are given below:

Ballymore-Eustace Water (supplies to over 90% of County)
mg/L CaCO3 = 50
eH (Clarke or English Degrees) = 3.5
dH (German Degrees) = 2.8
fH (French Degrees) = 5
Mmol CaCO3 = 0.5
American Hardness Degrees (ppm) = 50

Leixlip Water (blended supply to area in north of County, mainly in Lucan)
mg/L CaCO3 = 150 - 300
eH (Clarke or English Degrees) = 10.5 - 21.9
dH (German Degrees) = 8.4 - 16.8
fH (French Degrees) = 15 - 30
Mmol CaCO3 = 1.5 - 3.0
American Hardness Degrees (ppm) = 150 – 300
