Yorkshire Water has broken ground on the fifth storm overflow discharge reduction project in Leeds, on Wyther Lane in Kirkstall.
The £2.2m project will see the installation of a new storage tank on Wyther Lane, which will hold excess wastewater, and rainwater flows during periods of heavy or prolonged rainfall.
By creating additional capacity in the network, the scheme will reduce discharges into the river Aire.
Storm overflows are designed to act as a relief valve for the combined sewer network, which carries both wastewater and surface water, during periods of heavy or prolonged rainfall. They discharge when the system is at capacity to prevent flows backing up and flooding homes and gardens.
Carried out by contract partners Ward & Burke, the work is expected to take a year to complete. When finished, discharges from the overflow will be reduced to less than 10 per year.
Dan Rhodes, project manager for Yorkshire Water, said: “Storm overflows across the region are operating more often than we, and our customers, would like, but we’re making significant headway with our programme in Leeds.
“We’ve now started five projects in Leeds, and over the next five years, we’re planning to bring the number of discharges from overflows in the area down by 72%.”
West Leeds storage tank projects are also on track at:
- Village Place storm overflow in Burley, reducing discharges into the river Aire
- Fraser Avenue in Horsforth, reducing discharges into the river Aire.
Other work includes Headingley Station storm overflow, which reduces discharges into the river Aire, and Millshaw storm overflow in Beeston, which reduces discharges into Farnley Wood Beck.
The work in Leeds forms part of the utility’s £1.5bn storm overflow investment project between 2025 and 2030 and follows a £180m investment over the previous two years that helped to reduce discharges to the region’s watercourses by 12% in 2024 compared to 2023.
