Yorkshire Water has successfully completed a £0.5m project at Thurnscoe Combined Sewer Overflow (CSO) to reduce storm discharges into Thurnscoe Dike in its continued commitment to improve water quality in the river Dearne.
Contractor Mott Macdonald Bentley (MMB) recently completed the project to lay a new surface water sewer pipe and new manhole to intercept and redirect surface water, typically highway run off during extreme wet weather events, into an adjacent 1200mm surface water system and away from the storm overflow.
The project should result in a reduction of discharges from the storm overflow going into Thurnscoe Dike, helping to improve water quality in the area. It’s one of a number of storm overflow projects to improve water quality for the river Dearne and river Don in south Yorkshire.
These projects include:
- £2.3m at Cloughfields to reduce discharges into a tributary of Harley Dike
- £1.8m at Church Street, Jump to reduce discharges into Jump Valley Stream
- £2.8m at Elsecar to reduce discharges into Knoll Beck
- £2.4m at Cudworth to reduce discharges into Small Bridge Dike
- £2m at Barugh Green, to reduce storm overflows into the river Dearne
Matthew Wilson-Wright, senior asset planning sponsor, Yorkshire Water said: “We’ve seen significant investment in the South Yorkshire region to reduce storm discharges and improve water quality as part of our £180m investment across Yorkshire by April 2025 to reduce storm overflows into watercourses and the environment.
“Yorkshire Water is set to deliver its largest ever environmental investment between 2025 and 2030, with £8.3bn to be spent across the region. This includes over £1.5bn investment to continue to reduce storm discharges into watercourses over the next five years.”
Details of Yorkshire Water capital investment schemes in the region and beyond to date, can be found on the Storm Overflow Investment Map.
