Project Summary
Coffey delivered the civil works for the Waterford Main Drainage Project – Wastewater Treatment Plant. The scheme principally involved the construction of a new treatment facility to serve Waterford City and the adjoining area of County Kilkenny, known as the environs of Waterford City. The project also required the construction of a sea outfall from the new plant to the estuary of the River Suir.
Project Description
The wastewater treatment plant was designed to treat domestic, commercial, and industrial effluent from Waterford City and Environs, with a capacity for a population equivalent of 188,000. The works included the design, construction, commissioning, testing, and operation of a complete wastewater and sludge treatment system, with final effluent discharged via a sea outfall. Civil works were undertaken by Coffey, with M&E design and build delivered by Enpure Ltd.
At the Belview site, Coffey constructed major reinforced and precast concrete structures, settlement and aeration tanks, digestors, and sludge facilities, alongside associated buildings, pipelines, groundworks, and landscaping.
