Chobham sewage treatment works upgrades

We’re investing over £12 million in upgrading Chobham sewage treatment works. As part of the project, we're working with contractor Galliford Try. We'll be installing new screening and treatment equipment at the plant.

When we'll be working

The project has already started and construction finishes in April 2025.

How this may affect you

Whilst we work we’ll do all we can to reduce disruption.

We have a large excavator on site, and we’ll need to ‘track’ this along Broadford Lane when we’ve finished using it. This may slow traffic on the road for up to 30 minutes.   

Benefits to the local community

We know the area is prone to flooding and we’re sorry if this has affected you in the past. 

The new equipment will help us:

• Screen and treat more wastewater as it arrives
• Reduce the amount of untreated water our storm tanks release into the river during bad weather 
• Stop sewage odour building up by easing the pressure on our storm tanks
