South Leinster GWS DBO Project
T J O’Connor & Associates were engaged by Carlow County Council to act as Client’s Representative in connection with the construction of new Water Treatment Plants for 18 Group Water Schemes and 15 public water supply schemes spread across six counties (Carlow, Kildare, Kilkenny, Laois, Wexford, Wicklow).
As part of the project 34 new Water Treatment Plants were constructed, as some schemes have more than one plant. Raw water is from groundwater/spring sources as well as stream sources, in a limited number of cases. The new water treatment plants were procured under a single DBO contract.
The quality of the raw water varies and includes removal of colour, turbidity, iron, manganese, aluminium with disinfection through chlorination. The plants are designed to be operated and monitored remotely using GPRS technology to provide a telemetry system. Construction commenced in November 2006 and was completed in June 2009.
May 2006 – Jun 2009
- 34 new Water Treatment Plants with a combined design throughput of 8,688 m3/day
- New wells, pumping stations and raw water pipelines and reservoirs
