United Utilities Water has appointed long-term construction partner Black & Veatch to a £56m contract to replace waste water treatment works at Chadderton and Royton in Oldham.
The requirements include meeting new final effluent discharge consents at both works and reducing storm sewage discharges to improve river water quality in the River Irk, and its tributaries.
UU said it will cease full treatment at Royton and transfer flow to Oldham for full treatment, where new secondary and tertiary treatment facilities will be provided. At both sites additional storm storage is required to reduce discharges to watercourse to meet required River Water Quality standards.
The contract won by Black & Veatch comprises the design, procurement, construction, commissioning and operation of new wastewater treatment facilities at Oldham and Royton, together with transfer pipeline and pumping station.
The two plants are around 4km apart at Street Bridge in Royton and The Causeway, Broadway Business Park in Chadderton.
Black & Veatch has worked with United Utilities since 1974.
