The Shanganagh Waste Water Treatment Works (WWTW) was completed as part of the Shanganagh Bray Main Drainage Scheme. The Project required the design and construction of a WWTW at the site of the existing works and the refurbishment of the Bray Pumping Station.

This project also includes the operation and maintenance of the existing and newly constructed Shanganagh WWTW, Bray Pumping Station and Bray Stormwater Storage Tank until 2032.

The plant is considered an essential service and operates on a 24 hour basis. The plant provides pre-treatment, full secondary treatment and drying of sludge while delivering energy recovery through biogas generated as part of the treatment process.
