Thames Water to begin London sewer upgrade works

Thames Water will begin work on two underground storage tanks this month in Westbourne Green and Tamplin Mews Gardens to protect homes and businesses from sewer flooding in London, UK.

Once complete, the tanks will take sewage and stormwater away from overloaded main sewer pipes and store it until spare capacity in the network becomes available to transport it to the nearest sewage treatment works.

The company will build two sewer overspill tanks under Westbourne Green that will be 20m deep and 20m in diameter. The tanks will have the capacity to hold up to 6.3 million litres of wastewater.

A smaller tank in Tamplin Mews Gardens will be 15m deep and 15m in diameter with a capacity of 2.65 million litres.

Since the end of August 2013, contractors have been working in Chippenham Road and Formosa Street to build manholes and lay new sewer pipes and are now ready to begin the next stage of the project.

Thames Water senior contracts manager Mark Cooper said that the project is vital to protect homes and businesses from the misery of sewer flooding.

"We appreciate that our work will cause some disruption but it’s important to stress that areas of both parks will remain open while work takes place in them," Cooper added.

"We’ve been working very closely with local people to try and accommodate their needs and would like to thank everyone for their understanding."

The project is expected to move away from Tamplin Mews Gardens by December and Westbourne Green by March 2015.
