GENERAL PROJECT

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.

Update by Jane Cooper

Hello, 

Site is now well established and civil works are underway. The old washwater building at the North end of site has had some conservation work carried out on it to ensure that the bats that were present were rehomed successfully.

This building has now been demolished to make way for the new one currently being built off-site. Work is also underway at the South end of site to install a pumping station for the  new Tertiary plant.
