United Utilities starts £38m water improvements in Bolton

When work completes in March 2025, a series of tunnels and storage tanks in Bolton will help reduce storm overflows – one of the leading causes of water pollution in the country.

United Utilities’ plans will improve the water quality at Astley Brook, Bradshaw Brook, Eagley Brook, and Gale Brook.

Storm overflows are a safety mechanism where water from sewer systems will be released into rivers, lakes, and brooks in an effort to prevent flooding. This tends to happen in heavy storms where the existing drainage systems are overloaded.

United Utilities will reduce the need for storm overflows by increasing the system’s capacities with three different projects.

The first will see two storage tunnels built between Firwood industrial estate, Bolton Arboretum, and Longsight Park. These will be capable of storing more than 3,500 cubic metres of water, preventing it from having to be discharged into Bradshaw Brook during times of weather distress.

The second project comprises the building of a 400 cubic metre storage tank at Haywood’s Hollow, as well as a new screen. This will help Astley Brook.

Over in Dunscar Bridge, the third project will also see a storage tank built – this time 200 cubic metres – and a screen fitted. This will improve the water quality at Eagley Brook and Gale Brooke.

Last year, United Utilities said it would invest £13.7bn into its infrastructure and services to help improve water quality and provide additional support for customers. This plan needs to be approved by the Water Services Regulation. United Utilities is optimistic it will have a final verdict on its upgrade plans before the end of the year.
