Thames Water will put its plans to protect Swindon homes from sewer flooding on show on Monday next week.
Thames Water is inviting residents to see its plans for a £4.5 million upgrade to the area’s sewer network. The scheme will involve the construction of two underground storage tanks - 1,000 and 500 cubic metres respectively - to capture wastewater during times of heavy rain.
Andrew Popple, Thames Water’s head of programme delivery, said:
"The northern part of Swindon has seen major development over the last decade and, although the network is largely working as it should, this project will make sure that it is fit for the future.
"Extra homes will mean extra pressure on the network so this is proactive work to prevent problems happening further down the line.
"The two underground tanks will capture flows of wastewater during storms to prevent sewage from backing up into homes and gardens. It will also make sure our sewers are ready for any further expansion of the town."
The project is expected to take up to a year to complete. The work forms part of the water company’s £1 billion-a-year investment programme to upgrade its pipes, sewers and other facilities across the five-year period.
With the UK government demanding a 50% reduction in storm overflow spills by 2029, the era of reactive management is over. Speaking in the House of Commons on 21 July 2025, then environment secretary Steve Reed said, “This Government will cut water companies’ sewage pollution in half by the end of the decade.”
