£5m investment in Chesterfield storm overflows to reduce discharges to local watercourses
7/12/2024
Yorkshire Water is planning to invest over £5m in three storm overflows in and around Chesterfield to reduce the number of storm water charges into Calow Brook, the river Hipper and the river Rother.
The three projects will start in the next two months and include:
- £1m to add 150m3 of new storage to the sewer network on Oaks Farm Lane, Calow, reducing discharges to Calow Brook by 84%
- £3m to add 346m3 of new storage to the sewer network adjacent to Avenue Farm, Grassmoor, reducing discharges to nearby watercourses by 68%
- £1.1m to create 95m3 of new storage to the Oakfield Avenue area reducing discharges into the river Hipper by 75%
Once completed, the storage at all three sites will hold almost 600,000 litres of wastewater during periods of heavy or prolonged rainfall, before returning it to the network for full treatment once the rainfall event has passed.
The projects are part of a £180m investment project across Yorkshire by the end of April 2025 to reduce discharges from storm overflows.
Work will be carried out by Galliford Try and will begin this month at Oaks Farm Lane and Avenue Farm, with work at Oakfield Avenue due to begin in August. All three projects are expected to be completed in early 2025.
Martin Ineson, project manager at Yorkshire Water, said: “We are committed to improving watercourses across Yorkshire and are investing £180m by April 2025 to reduce storm overflows.
“We assessed a variety of options for these two sites and, due to a range of factors, increasing storage within the network was the best option. The increased storage at these sites will enable the network to capture and store storm water during periods of heavy and prolonged rainfall, significantly reducing discharges into the Calow, Hipper and Rother. The stored storm water will then go through the full treatment process once the rainfall event has passed and flows within the network have returned to normal levels.”
