GENERAL PROJECT

Chilton Lane Sewage Treatment Works upgrade

As part of the Water Industry National Environmental Programme (WINEP), we will be installing chemical dosing plant (ferric sulphate and sodium hydroxide) to enable the site to meet a revised Phosphorous discharge consent of 0.2 mg/l, which will apply from December 2024. Phosphorous is a nutrient and can cause algae to grow in watercourses, reducing biodiversity and river water quality. The improvement works will cost around £4.3m and is one of 27 sites within the NWG region to receive this upgrade.

Good morning, I just wanted to give a quick update on the site teams progress over at Chilton Lane STW. The final infill for the Chemical dosing has now been completed. Our paving areas on site are now 100% complete. Although the weather has been quite challenging, when there has been opportunity all planned tasks have been fulfilled. Formwork for the Mecana (MCC) has been completed this week and the concrete has been poured ready for the kiosk installation. In the next month the team will be installing the MCC/kiosk and enabling works will begin for the pumping station construction. I have included some photos of the progress. As always feel free to leave a comment should you have any questions, and a member of the team will get back to you. Thanks Anya

Good afternoon, I just wanted to let you know how our site team are progressing with the construction work at Chilton Lane STW. The sub base (capping layer) to the concrete road has been installed. As mentioned in our last update, the Northern Power Grid Kiosk is now complete. The bases to the Mecana, NSAF and Chemical Dosing Tanks that improve the quality of the flows and capacity of the works have been dug out and stoned up. The ducting works which feeds cables around the works are currently ongoing. The Primary Ferric Dosing Point of Application (POA), Secondary Dosing POA and Caustic Dosing POA have been completed (see photos for reference). This area of the STW adds chemicals into the flows to ensure its treated to a high standard. The Mecana blinding has been poured ready for the concrete base slab to be poured next week In the next month or so the MCC trough will be installed, the under slab works to the NSAF will be carried out, the team will continue with the ducting works and the drainage works will be constructed for the Mecana. I have included some photos for you to view. Please feel free to leave a comment below should you have any questions and a member of the project team will get back to you.

Good afternoon, Since our last update, the site team have been busy setting up our new compound area. The stone laydown area has been laid, and the site cabins have been delivered and are now up and running. The area for the new Northern Power Grid (NPG) Kiosk has been dug out and ready to be stoned up in preparation for the concrete base to be poured. Once we return to work after the Christmas Break, the new kiosk will then be installed. The new access road area has also been dug out ready to be stoned up. The site will be closing down for the Christmas break from Wednesday 20th December until Tuesday 2nd January. On behalf of the project team, we hope you all have a wonderful Christmas and New Year!
