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.

Hello,

Progress on the civil works at Knitsley continues well and the pumping station at the south of the site is now complete.

Due to the narrow access road, a rethink on the dosing kiosks has had to take place, with the result being we will now complete some additional works on site to enable smaller equipment to be delivered.

This will result in the overall works being prolonged for a two-three month period, with dosing now due to start around March 2025.
