project description:

The Lough Talt Regional Water Supply Scheme (RWSS) project is an outstanding example of civil engineering excellence. RPS carried out detailed hydrological and geological investigations over a number of years at Lough Talt which indicated potential impacts on the Lough Hoe SAC during extended dry weather.  Based on the reporting by RPS, Sligo County Council in a landmark ruling in 2019 granted planning permission to upgrade the existing Water Treatment Plant (WTP). This was the first project in Ireland to gain permission utilising the Habitats Directive Article 6(4) derogation process. The work, completed in 2020, included the use of chloramination as the residual disinfectant, eliminating the need for chlorine boosters.  The plant upgrade facilitated the removal  of 13,000 residents from ‘boil water’ notices and removed Lough Talt RWSS from the EPA’s remedial action list.
