Slaley WINEP P & Improvements

As part of the Water Industry National Environmental Programme (WINEP), we will be installing a new chemical dosing plant (electro coagulation) and replacing parts of the existing 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 £5M 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.

Project updates

Update by Julie Oakley

Hi All,

hope you are all doing OK, especially with the all the rain we have been having, 

Its been a while since I put on a progress report of how we are getting on with upgrading of the treatment works in your area. Since the last update we have removed the old boundary fence on the western side and replaced with new stock-proof fencing and with the extra space we have created a stone access road into site. We have now got the Motor Control Centre (MMC) precast units installed and backfilled, we have also cast the concrete base slab for the Soneco unit which is a chemical free wastewater filtration method. Work to demolish disused features of the site are continuing and new ducting is being installed. Next week we will see the Northern Power Grid (NPG) kiosk being delivered and the Motor Control Centre (MCC) slab constructed.

We would like to thank you for all your continued support and patience while the works progress.

If you have any questions or queries please feel free to leave a comment below or use the contact details provided to get in touch.

Thank you

Good afternoon,

I hope you all have had a lovely Bank Holiday weekend and are looking forward to the next one, I thought I would just touch base with an update on the progress of the project here at Slaley.

We are planning some “head start” works from 20th May – setting up and preparing the farmers field for our compound, cabins and parking. You will notice there is more traffic than normal over the first few weeks this is just until we have the site up and running.

In the meantime if you have any questions or concerns please leave a comment below or contact us on the details provided.


thanks for your patience

Planned work in your area


Good morning, 

As you might already be aware from our recent letter. We’re embarking on a project to upgrade the sewage treatment works in Slaley. This project is part of a £5,000,000 investment aimed at enhancing water quality in Reeston and March Burn as a key deliverable of the Water Industry National Environmental Programme (WINEP). The goal is to ensure continued resilient wastewater services for our customers.

All of work will take place within and directly adjacent to our site boundary and will be undertaken by our supply partners Mott MacDonald Bentley (MMB). We don't anticipate any disruption for you, we just want to make you aware that you may notice an increase in activity and some heavy vehicles using the access route close to the village. Please be assured we are committed to keeping all disruptions to a minimum.

Work is due to start on site week commencing the 3rd of June, working Monday to Friday between the hours of 8:00 AM and 6:00 PM with the current programme expecting us to be on site for 12 months.

We’re hosting a customer event on the 9th of April at Slaley Commemoration Hall between the hours of 3pm and 6pm. This is a great opportunity to learn more about our project, ask questions and share your thoughts with the project team. It would be great to see you there.

If you are not able to make our customer event, you can always reach out by leaving a comment on this post and one of the project team will be in touch or alternatively you can call our customer contact centre on 0345 717 1100.

Either way we would love to hear from you and get your feedback on our plans.
