Deephams Sewerage Treatment Works

Client: J. Murphy & Sons

Deephams Sewage Treatment Works (STW) is one of the largest wastewater treatment plants in the UK and was upgraded between 2013 and 2019 to accommodate a 989,000 population equivalent.

Thames Water contracted Murphy to carry out the Deephams STW Upgrade. The aim of the project was to improve the quality of effluent released into the River Lee, to comply with more stringent Environmental Agency standards, and to reduce odour levels by 90%.

The works included new treatment structures and plant, odour control plant, improvements to waste gas recovery, energy generation and new facilities for operations staff.
