A partnership between the Environment Agency and Oxford City Council has secured the necessary infrastructure to develop around 18,000 new homes in and around Oxford.
This move aligns with the Government’s ambition to unlock growth and deliver homes and investment for local communities.
The initiative could serve as a blueprint for unlocking similar projects across the country, where adequate wastewater infrastructure is essential before development can proceed. The EA had previously challenged planning applications over concerns about sewage treatment capacity, which posed risks to water quality.

Chief Executive of the Environment Agency, Philip Duffy, said:
“After a rigorous process, we have secured the water services and environmental protections which communities in Oxford need to thrive in their new homes. Oxford City Council now have everything they need to decide if the development goes ahead.
“The Environment Agency believes that protecting the environment and sustainable development can go hand in hand, now and into the future. This kind of powerful partnership working is exactly what’s needed to unlock homes and jobs whilst protecting nature.”
Following a rigorous process, the Environment Agency, Oxford City Council, and Thames Water have agreed on a scheme to provide the required capacity at the Sewage Treatment Works. This will allow for the occupation of new developments from 2027, in line with local plans.
Technical experts at the EA have ensured that Thames Water has presented a clear, fully costed, and funded programme of work. This provides confidence that water quality will be protected and that communities will have the necessary water services while enabling projected growth.
The Environment Agency will soon be writing to Oxford City Council and other affected Local Planning Authorities with their revised advice.
