Doosan Enpure appointed lead contractor on £22m Woodmansterne WTW upgrade

Sutton and East Surrey Water’s £22m project to upgrade Woodmansterne Treatment Works in Chipstead, Surrey, has been awarded to Doosan Enpure who will deliver the works as principal contractor.


The contract as a whole will be delivered by Doosan Enpure, SESW, CJ Thorne and Harold James.


SESW Project Manager Chris Stanbridge said “We are looking forward to working with Doosan Enpure on this important strategic project to help secure water supplies for existing and future customers throughout our supply area.”


Avtar Jirh, Managing Director of Doosan Enpure added: “we are delighted that we have been awarded this significant contract after a rigorous competitive process and we look forward to working with the SESW team.” 


The contract scope includes detailed design, engineering, procurement and construction (EPC) of key new assets including a 50 Ml/d Rapid Gravity Filter plant, Chlorine Contact Tank, high lift treated water pumping station, standby generator, surge vessels, as well as mechanical and electrical upgrades.


The existing WTW was constructed in 1905, with water being supplied to it via deep boreholes in the underlying chalk aquifer. The works will be upgraded to treat a maximum throughput of 50Ml/d, delivering potable water through the local network more efficiently and resiliently.


Due to the operational importance and location of this works, this project will require careful sequencing of construction to enable the various parts of the existing works to be decommissioned and then transferred to the new facility.  Engagement with the local community will be paramount throughout the project.
