Thames Water to begin energy upgrade works in Twickenham


10 August 2022

Thames Water is installing new technology at the Mogden Sewage Treatment Works that will 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 development of a small area of the treatment works site for the new equipment together with a new 1km biomethane export pipeline from Thames Water’s Waste Water Treatment site on Mogden Lane to Chertsey Road where it will connect to the gas grid network. Local wastewater and gas services will not be impacted.

Works to install the new pipeline will begin on Monday 15 August in Whitton Road. Engineers will be working on site Monday to Friday 7am to 7pm. If required, weekend working hours will be Saturday 9am to 4pm and Sunday 9am to 1pm. 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 in 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 from site for the Autumn internationals at Twickenham in November 2022 and all of December 2022. The works will then resume in Mogden Lane in January for a three-week period 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.

Further details on the project can be found on the Thames Water website.
