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.


What will the working hours be?

Typical working hours will be Monday to Friday, between 8.00am and 6.00pm. If required, work may also be carried out between 8.00am and 1.00pm on a Saturday. We will notify you in advance when weekend working may be required.

Will my water supply be affected?

We do not plan to disrupt your water supply while work is carried out on this project.

Will the work cause disruption?

The work will be concentrated on Slaley Sewage Treatment Works which is located near Flothers to the south of Slaley village. During certain stages of construction work there will be an increase in traffic entering the construction site from the road to the south of Slaley village, although we do not expect this to be significant.

Will access to my property be maintained?

Access to your property will be maintained at all times.

How will residents be kept updated?

We will keep your Community Portal updated with key information about our progress.

You can also contact us on 0345 717 1100 and arrange a call back from our project team. If you will be directly affected by our work our site team will get in touch in advance of the work starting. We will also keep you informed with project progress with regular newsletters.

Will the site be dangerous?

The site will be operated by our framework partner Mott Macdonald Bentley, an experienced contractor working to tight health and safety standards. Working areas will be securely fenced off from public access at all times.

We do ask that everyone respects the site fencing, signing, guarding and instructions of our team when required for your own safety.

What will it look like when the works are complete?

The work will create new assets on an existing operational site but the appearance of the site from nearby footpaths will be very similar to how it looks now.  We will reinstate any damage caused to access roads and tracks during the work.

Will there be dust, vibration and noise?

The construction work we carry out can involve using large machinery, digging up ground, pouring concrete and working with granular materials which will result in some dust, vibration and noise. The site team will do everything they can to minimise any inconvenience caused by this and will make sure that the work is carried out safely.

Will the roads be kept clean during the works?

The work will involve digging up and transporting significant volumes of soil and other excavated materials to storage or for disposal which may cause dirt on the roads. The site team will employ a road cleaning specialist with mechanical road sweepers which will be used to maintain the roads affected.

Will I be able to access my drive or directly park outside my property?

The work will not affect the ability of residents to park outside their property or access their drives
