Crookhall Sewage Treatment Works – WINEP Phosphorous Removal

As part of the Water Industry National Environmental Programme (WINEP), we will be installing a chemical dosing plant (ferric sulphate and sodium hydroxide) to enable the site to meet the forthcoming phosphorous discharge consent of 0.9 mg/l, which will apply from April 2025. The improvement works will cost around £1.5m, and is one of 27 sites within the NWG region to receive this upgrade. Phosphorous is a nutrient and can cause algae to grow in watercourses, reducing biodiversity and river water quality. Our works will help to improve the quality of the downstream watercourses.

Update by Sarah Jayne Parvin

Good morning, we would like to provide you with an update since we started on site 21 February. All enabling works such as trimming trees and establishment of the compound are now complete. Temporary repairs to the road have been done and we intend to carry out permanent improvements in Autumn. Traffic Management has been installed from the roundabout, up the lane to the treatment works to ensure safe access and egress to our staff and the public.

This week ground stabilisation work has commenced, which involved drilling pile’s into the ground, in preparation for above ground works. This will take around 4 weeks to complete.

We would like to thank you for your patience throughout this project and If you have any questions or concerns please use the contact us button at the top of the page.
