GENERAL PROJECT

Carlton & Redmarshall Sewage Treatment Works upgrade

As part of the Water Industry National Environmental Programme (WINEP), we will be installing chemical dosing plant and other improvements to the treatment process to enable the site to meet the forthcoming Phosphorous discharge consent of 0.7 mg/l, which will apply from December 2024. The improvement works will cost around £3.4m 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.
