Wedoany.com Report on Feb 15th, Yorkshire Water has recently completed an £18 million upgrade project at the Dewsbury Wastewater Treatment Works. This project, delivered in partnership with BarhaleEnpure JV, replaced the original 14 primary settlement tanks with three larger new tanks and two new primary sludge pumping stations. It also introduced chemical dosing facilities to reduce phosphorus levels in the final effluent.
In addition to the new chemical dosing system, process improvements, and a 2.5-hectare biodiversity and rewilding area, the works remained fully operational during construction, serving a catchment area of approximately 200,000 people. These enhancements exceed regulatory requirements, reducing phosphorus in the final effluent by around 90%, thereby enabling the Dewsbury Wastewater Treatment Works to successfully meet the targets of England's Water Industry National Environment Programme (WINEP).
Philip Lister, Head of Environmental Permits Compliance, said: "Yorkshire Water is committed to finding innovative ways to improve operations at our works to achieve phosphorus removal targets. This specific project implemented a range of measures aimed at reducing carbon impact and accelerating the pace of improvement works. We have committed over £350 million to reduce phosphorus entering watercourses at 85 wastewater treatment sites across our region over the next five years, continuing the work we started between 2020 and 2025."
The project was completed on time and within budget, employing modern construction methods to reduce carbon emissions, minimise disruption, and maximise local benefits. This included using local suppliers, providing apprenticeship opportunities, and community engagement. Brian Harrold, Contract Manager for BarhaleEnpure JV, added: "We worked closely with Yorkshire Water to deliver this significant phosphorus reduction project. It will significantly improve water quality in the River Calder, creating a healthier and more pleasant environment for people and wildlife, and increasing recreational opportunities."
