A summary of what was discussed regarding the unacceptable discharge of sewage into the River Yeo at Mudford Pumping station when it rains, and sometimes even when it doesn’t leaving local residents awash with sewage. A year on and nothing has changed!

Housing Development Planning: Water Companies
(Volume 763: debated on Wednesday 12 March 2025 in Parliament.)

Sarah Dyke (Glastonbury and Somerton) (LD)
I thank my hon. Friend for securing this really important debate. Speaking of medieval villages, I met residents of a little village called Mudford in my constituency last week. Two new housing applications have recently been approved for up to 1,000 homes just upstream on the River Yeo. Mudford already suffers from extreme flooding and relies on inadequate and fragile sewerage systems that already overflow regularly during heavy rain. Worryingly, the developers plan to use the same system despite clear environmental risks. Does my hon. Friend agree with me that water companies must be fully involved in the planning system, to ensure that water infrastructure can handle the demand and prevent future flooding and spills of sewage?

My hon. Friend describes a situation that I think we are all familiar with. I agree with her about the role of water companies and will go on to talk about that point at some length in my speech, so I thank her for that intervention.

When there is heavy rain, the residents I met struggle with surface water flooding and, unfortunately, with sewage backing up into homes and gardens, which we all agree is pretty horrible. Further homes in the area are in the planning process, so the residents are extremely concerned. Each year, their situation gets worse. An elderly resident told me that sometimes, when it has been raining heavily, she has to ask her neighbours not to use their bathroom, because sewage will flood into her garden if they do. That is not a position that any homeowner should be put in, so we need to ask ourselves how we have allowed this to happen in the first place.

We are acutely aware of the need to build more homes, and we support the Government in their mission to build more homes, but it is essential that the infrastructure for both new and existing residents keeps pace with development. Astonishingly, water companies are not statutory consultees when a housing development goes through the planning process. That means that there is no statutory safeguard for home buyers that the company responsible for dealing with their foul waste has ensured or confirmed that its existing sewers will cope; nor is there any statutory safeguard for existing residents against a new development bringing some unpleasant surprises.
