Work begins on nature-based wetland in Ilkley as part of £60m Yorkshire Water investment
Work to build a nature-based wetland near Leeds has got underway.
Construction began on the new Ilkley and Addingham Wetland yesterday (Monday, April 13), marking the next step of a £60 million investment to improve water treatment and the water quality of the river Wharfe.
The project forms part of Yorkshire Water’s largest ever environmental investment programme, running from 2025 to 2030, which will see £8.3 billion invested across the region to upgrade infrastructure and improve services for customers.
Andrew McKinley, Senior Project Manager at Yorkshire Water, said: “This project is a great example of how we’re using nature-based solutions to improve river water quality while delivering wider environmental benefits.
“By harnessing natural processes, this wetland will provide an effective final stage of treatment while also creating new habitats and enhancing biodiversity in the local area. It’s an important investment for Ilkley, and for the long-term health of the river Wharfe.”
Once complete in 2027, the integrated constructed wetland will provide a final stage of wastewater treatment using natural processes. Water from the upgraded Ilkley Wastewater Treatment Works will be transferred under the river Wharfe to the wetland, where it will flow through six interconnected lagoons.
Within these lagoons, a range of carefully selected wetland plants will naturally treat the water, reducing the need for chemicals or powered equipment, before it is safely returned to the river via a new outfall.
The scheme is designed to deliver multiple environmental benefits, including improved river water quality, a net gain in biodiversity, and the creation of a more natural landscape that can be enjoyed by the local community from nearby public rights of way.
Yorkshire Water will host a public drop-in session at the Clarke Foley Community Hub on Wednesday, April 22 from 7.30pm-9pm, where local people can find out more about the project, view plans, and speak to the project team.
