Costain/MWH joint venture bags Southern Water deals worth £65m

A joint venture between Costain and MWH Treatment has won contracts with Southern Water valued at £65m as part of the water company’s AMP7 investment programme. 

The projects will improve the resilience of the local water supply and upgrade wastewater treatment works at two sites, and will run until late 2025.

The joint venture team will work with Southern Water and its engineers across both sites to develop cost-efficient solutions, optimise asset performance and deliver the implementation through to the end of AMP7. Both sites will benefit from major renovation, refurbishment and expansion of existing assets to cope with rising demand for drinking water and increasing volumes of wastewater.
