QUESTION NO.2
QUESTION: Councillor Yvonne Collins
To ask the Chief Executive to confirm that water supplies are sufficient to meet ongoing needs throughout the functional area given the recent good weather.
REPLY:
2022 has been a warm, dry year to date with mean temperatures consistently exceeding Met Eireann’s Long Term Averages (LTAs) and monthly total rainfalls generally less than LTA.
SDCC water demand has reflected the peak temperatures this year of 31.9oC (18th July) and 27.6oC (10th August), with corresponding demands of 92.9ML/day and 89.5ML/day which supply is sufficient to meet.
Seasonal fluctuations in demand, whether cold/hot weather related, are controlled by continual management of regional Water Treatment Plant production and Storage Reservoir capacities together with both Pressure and Leakage Management of the water distribution network.
Water demand in SDCC has, with domestic and commercial growth, increased from an LTA (2010-2022) of 75ML/day to it’s current 2022 average of 84.2ML/day. Irish Water is responsible, since 2014, for the planning for future demand. The National Water Resources Plan (2021) sets out a 25-year strategic plan to provide secure and sustainable water supply to cater for ongoing development. https://www.water.ie/projects/strategic-plans/national-water-resources/.
