The Four Roscommon Regional Water Supply Schemes (RWSS) project was a critical strategic initiative designed to provide a sustainable supply of high-quality drinking water in full compliance with European Communities Drinking Water Regulations (ECDWR). The project addressed a vital public health need by implementing an innovative approach that consolidated five separate Water Treatment Plants (WTPs) across the county into one unified project. This logistical and engineering feat enabled the permanent removal of long-standing boil water notices for approximately 31,400 people.
The infrastructure development spanned the length of County Roscommon, from North to South, encompassing the South Roscommon, Roscommon Central, Boyle Ardcarne, and Arigna schemes. The scope included the design and construction of five new WTPs located at Lisbrock, Killeglan, Ballinagard, Rockingham, and Ballyfarnon. These facilities provide a combined treatment capacity of 22,550 $m^3/day$, supported by 28 production well boreholes, associated pumping stations, and rising mains.
Jennings O’Donovan provided comprehensive consultancy services throughout the project lifecycle, including a Design Review Report, detailed design, and the management of Water Abstraction Orders. The firm also oversaw Environmental Risk Assessments, the tender process, and Construction Administration. Following the Design-Build phase, the project includes a 20-year Operation and Maintenance (O&M) period to ensure the long-term reliability of the water supply network and its associated telemetry and instrumentation systems.
