Good afternoon Everyone, welcome to your monthly update on the upgrade of the treatment works here at Horsley. We are making good progress on site and have now completed the RGF’s (Rapid Gravity Filters) which are now operational and fully automatic. This has allowed us to fully remove the temporary syphon pipe including the permanent reinstatement of the road crossing on Water Lane. Other highlights has been the substantial completion of the lifting monorail in the Chemical building, significant progress with the final reinstatement works across site and completing the majority of training with operational personnel. We will keep you updated as best we can on a monthly basis but in the meantime if you have any questions, queries or issues please leave a comment below or use the details provided to contact us and one of the team will get back to you. Thanks again for all your patience and co-operation whilst the works are ongoing. Thank you Julie

Good afternoon, Everyone, Looks like that is it for our so called Summer, I hope you have all had a lovely one and looking forward to the autumn months ahead. It has been a while since my last update, so I thought I would just touch base with on how we are getting on in Horsley. Work on site is going well. We're almost done setting up the new filters, so temporary equipment can be removed soon. We've started working on the pre-dosing system, with only a few tasks left to complete. Preparation for the new chlorine contact tank has also started, which includes checking underground pipes, moving lights, and doing a trial to help finalize the design. We would like to thank you for all your continued co-operation and patience while the works are ongoing, if you have any questions or issues please leave a comment below or use the contact details provided and one of the team will get back to you. thank you Julie
