The new storm overflow and storage tank will be installed underneath Bilston Park. A new outfall to Bilston Burn will also be constructed to allow excess rainwater to be safely diverted
What We Are Doing
We are constructing a new Storm Overflow with a powered screen as well as a large storage tank under Bilston public park.
New sewer pipes will be installed, and a new outfall will allow excess rain water to be safely diverted into the nearby burn during extreme weather.

Why We Are Doing It
Working closely with the Scottish Environment Protection Agency (SEPA) Scottish Water identified priority storm overflows for improvement or replacement.
Under the banner ‘Draining the Rain, Enhancing the Environment’ the Improving Urban Waters investment will help reduce spills, improve water quality and prevent sewage related debris such as wet wipes from entering the environment during periods of rainfall.
