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 afternoon, Here is the latest update for Chilton Lane Sewage Treatment Works. All mechanical and electrical works on site are now complete, with only 80% of the civil works left. The new system has been brought live and is in the commissioning phase. The process lab has now been delivered and is fully complete. Effluent has begun passing through the new treatment process. In the next coming weeks the process will be commissioned and chemical dosing will be introduced. We will begin to look at our landscaping and planting works in preparation for completion of the project in November. As always please get in touch if you have any questions. Thanks

Afternoon, Here is our latest update for Chilton Lane STW: We are continuing to downsize our plant where necessary to utilise 90%. Our pours for the chemical dosing slab and footpath have been completed. The pipework to the Mecana (Motor Control Centre) is also complete. The pumping station valve slab and upstands have been poured. When on site our subcontractors have switched to using the main power which reduces the need for temporary sources. If there are any questions don't hesitate to reach out.

Good afternoon, Here's the latest update on our Chilton WTW project: - The cofferdam to the pumping station is complete, and the shaft has been constructed. - The Motor Control Centre panel has been installed on schedule, with Intelect on site for pre-cable work. - We've finished 80% of the main site excavation and drainage, allowing us to reduce our plant equipment. - We've also done several pours to improve the pumping and filtration process. I've attached some photos to show our progress. As always, if you have any questions or comments, please let us know, and someone from our team will get back to you.

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.
