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.

Good Morning,

Following our recent communication regarding our work we carried out on Wednesday 17th January in which we switched off a sewage pumping station in Bishopton Mill while we modified pipework on the Sewage Treatment Works site. I just wanted to let you know that additional work is due to be carried out on Thursday 25th January. The work is the same as before, we will use tankers to transfer effluent from the pumping station to the Sewage Treatment Works with the tanker route running along Mill Lane and Whitton village to the works to manage sewage flows at the pumping station. During this time, we may also need to access the pumping station at Thorpe Thewles via Vicars Close. 

Disruption will be kept to an absolute minimum during this time, and your water supply will not be affected.

Should you have any questions, please leave a comment below and a member of the project team will get back to you.

Thank you for your continued patience.

Good afternoon, and Happy New Year!

I just wanted to let you know of our planned work that is due to take place tomorrow. We will need to switch off a sewage pumping station in Bishopton Mill for approximately four hours while we modify pipework on the Sewage Treatment Works site.  To manage sewage flows at the pumping station during this time, we will use tankers to transfer effluent from the pumping station to the Sewage Treatment Works with the tanker route running along Mill Lane and Whitton village to the works.

Letters were hand delivered to surrounding properties yesterday which you can view here.

I will be posting a progress update in the upcoming weeks so keep a look out!
