Costain JV awarded Southern Water programme

Costain Group PLC ("Costain") announces that its CMDP joint venture with MWH Treatment has been awarded contracts worth £65m by Southern Water as part of the water company's AMP7 investment programme.

The work will run until late 2025 and will see the joint venture improve the resilience of the local water supply and upgrade wastewater treatment works at Testwood near Southampton, and Burham in Kent.

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

This contract extension adds to Costain's growing positions with leading water companies, which include Anglian Water, Northumbrian Water Group, Severn Trent Water, Thames Water, United Utilities and Yorkshire Water.

Alex Vaughan, CEO, Costain, said:

"We are pleased to extend our relationship with Southern Water and to bring our strategic expertise to critical upgrades of its infrastructure. We will ensure Southern Water continues providing clean drinking water to its customers while improving its resilience for the future. This is important work that will have a transformative impact on the lives of residents and local communities, and builds on Costain's growing positions with the leading water companies as they continue to improve the quality of our water supply."
