Knitsley Sewage Treatment Works

As part of the Water Industry National Environmental Programme (WINEP), we will be installing chemical dosing plant (ferric sulphate and sodium hydroxide) and a new tertiary treatment stage to enable the site to meet the forthcoming phosphorous discharge consent. The improvement works will cost around £4m, and it’s 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.
