Thames Water is installing new technology at the Mogden Sewage Treatment Works to produce enough renewable energy to heat around 3,500 local homes.

Thames Water will use excess biogas from the sewage treatment process to generate biomethane for supply to the local gas grid network.

The installation will involve the development of a small area of the treatment works site for the new equipment. A new 1km biomethane export pipeline from Thames Water’s Waste Water Treatment site on Mogden Lane to Chertsey Road will connect it to the gas grid network. The work will not impact local wastewater and gas services.

Works to install the new pipeline will begin on Monday 15 August in Whitton Road. Engineers will work on-site Monday to Friday, 7 am to 7 pm. If required, weekend working hours will be Saturday 9 am to 4 pm, and Sunday 9 am to 1 pm. The works are due to be completed by summer 2023.

Traffic will be managed through a combination of stop/go and temporary traffic light controls while working on Whitton Road. This will be followed by the closure of the northbound lane of Rugby Road while the pipeline is constructed from Whitton Road to the Mogden Lane roundabout, which is planned to be completed by 4 November 2022.

The works will be suspended and removed during the Autumn internationals at Twickenham in November 2022 and all of December 2022. The works will then resume in Mogden Lane in January for three weeks before demobilizing for the Rugby Six Nations fixtures at Twickenham throughout February and March 2023. The final elements of the works will then take place in Mogden Lane in April/May 2023.
