Yorkshire Water has completed a £1.6 million nature-first project at Bishop Wilton wastewater treatment works in East Riding of Yorkshire, designed to improve water quality in Bishop Wilton Beck.
The project was developed to reduce the amount of Phosphorous in the wastewater returned to the environment post treatment and is the first time that Yorkshire Water has implemented this type of technology.

Contract partner Eric Wright Water Ltd replaced two existing reed beds at the Bishop Wilton site with reactive media beds, which provide enhanced treatment of wastewater. The media beds use natural materials such as sand, gravel and plants to filter and absorb pollutants and Phosphorous.
Water quality in 15.4km of the Bishop Wilton Beck watercourse has been improved as a result of the project.
Rizwan Khan, project manager at Yorkshire Water, said:
“This kind of treatment process is innovative and kind to the environment, as well as being a reliable and robust system for wastewater treatment, and we’re delighted to have completed the project after plenty of collaboration and hard work with our partners, Eric Wright Water Ltd and ArmPhos Group Ltd.”
Alongside the media beds, the Bishop Wilton site saw the installation of two new pumping stations and a new control centre, improving the overall efficiency and reliability of the site.
Work on the project began in September 2023 and was completed in under a year.
Work is also underway with other nature-based solutions across theYorkshire Water region, including a £4 million wetland at Thornton-Le-Beans.
