Portlaoise Main Drainage
Laois County Council
Award-winning wastewater treatment in Irish Midlands.
This project involved design and construction of a new collection system, upgraded wastewater treatment plant and a new sludge treatment facility. It provides significant environmental benefits for the town of Portlaoise, its environs and the wider community.
The use of a gravity sewerage system in place of older pumping stations has reduced energy consumption and CO2 emissions. Improvements in water quality and the local environment were also achieved, particularly water quality in the Triogue River, which has allowed aquatic life to return and has provided enhanced protection to the River Barrow Special Area of Conservation 5km downstream. The project included a state of the art sludge management facility that has the capacity to treat all municipal sludges generated in County Laois. It was awarded the Engineers Ireland Environmental Infrastructure Award in November 2011.
