Severn Trent invests £1.2m to improve sewage infrastructure in Lea Marston 

Friday 25th September 2026

The Community in Lea Marston, Sutton Coldfield are set to benefit from improved wastewater services following the completion of a £1.2 million infrastructure upgrade by Severn Trent.

 

Now the water company is inviting residents and businesses to find out more about the project at a drop-in session on Wednesday, September 30, at the Hams Hall Environmental Centre, Coleshill, B46 1GA, between 3pm and 6pm.

 

The upgrade includes the decommission of the sewage treatment works at Lea Marston and the construction of a new transfer sewage pumping station in its place.

 

Work is scheduled to begin in October 2026 and continue until July 2027, starting at the Birmingham Road Treatment Works site before progressing along the Birmingham Road highway, then Church Lane and finally Canton Lane in Hams Hall.

 

Aaron McCusker, Senior Project Manager at Severn Trent, said: “Investing in projects like this is key to maintaining and improving our wastewater network for current and future customers. We recognise that work like this can be disruptive, and we will be working to minimise any impact for those living in the area. Our drop-in session is a great opportunity for residents and businesses to find out more and ask any questions they may have and hear about how we’ll be working in their local community.”

 

As part of the investment, a separate team will also build an underground sewer pipe network for the new National Grid Development off Hams Lane, with this work expected to begin in December 2026 and will be completed concurrently with the sewage transfer pumping station works.

 

To enable the work to be carried out safely, multi-way traffic lights will be in place on Birmingham Road for four weeks and on Church Lane for 19 weeks.
