Community Hub Admin Team •2 months ago Hello everyone,We hope you’re well.Following our last update in November 2025, we wanted to share how the upgrade at Horsley Water Treatment Works is progressing and what you may notice around the site over the coming months.Back in November, the main excavation for the new chlorine contact tank had been completed, and we were building the reinforced concrete levelling slab that helps supports the ground around it. Most of the slab will remain in place beneath the new tank, with only a small section removed at the end of construction so the leased land can be returned to its owner. We also completed modifications to the GAC building roof drainage associated with the construction of the temporary crane running pad. Since then, work on the new tank has made good progress. Installation of the pre‑cast concrete baffle walls is now underway, with 25 of the 116 units already in place as the internal structure begins to take shape. These baffle walls are internal walls that help control how water moves through the tank during treatment. The 135‑ton crawler crane positioned on the southern side of the site continues to support the heavy lifting required for this stage of construction.Preparations for connecting to the existing GAC filters have also progressed, with excavation works safely exposing the required pipework and services. Work on the new de‑chlorination chamber is advancing well, with the excavation and base now complete and the chamber due to arrive on site shortly for installation.Works on the Chemical Storage tanks have progressed well with tanks and Bund now installed. Works are now progressing with the connecting pipework, pumps and controls with works expected to be complete in April this year.As we move into the next phase of the project, you may notice an increase in activity around the site. Over the next few months there will be more deliveries, including the remaining concrete wall units, materials for the main tank build beginning in February, and large‑diameter pipework expected in April. Work will also begin on the new Break Head and Contact Tank chambers during this period. All drivers and subcontractors have been reminded to use the agreed access route into the site and to avoid travelling through Horsley village.You may also notice temporary task lighting during darker periods to allow work to continue safely. This lighting will be positioned carefully and directed only where needed, helping to minimise its visibility outside the site.Thank you for your continued patience while this essential upgrade progresses. We’ll keep you updated as work moves forward.
