A number of new projects that represent a £33 million investment are due to start at Horsley WTW as it is necessary to upgrade the treatment works in guidelines with the DWI, We have selected out partners Mott Macdonald Bentley (MMB) and Ross-Shire Engineering (RSE) to carry out the upgrades. The works consist of three separate contracts • Detailed design and construction of a new contact tank with associated pipework, sampling and dosing arrangements. NWG currently operate the Treated Water Service Reservoir (TWSR) as a combined storage tank and contact tank. This single compartment tank cannot be taken out of service without shutting the whole treatment works off and does not satisfy the DWI requirements for contact time. Thus, the construction of a new independent contact tank is required to satisfy DWI requirements and allow NWG to take the existing and new tanks out of service for regular maintenance without affecting the works output. The contact tank will be constructed at the South West of the works and will run from 2025 until late 2027 – This will be carried out by MMB • Pipework will be renewed on a pumping station (Birney Hill Pumping Station – BHPS) at the south of the works and on completion of the works will be commissioned and put into service allowing us to abandon the old pumping station on site. This work will will run from April/May 2025 and last for around 12 months - This will be carried out by MMB • Construction of new chemical dosing facility which will include the construction of two number new coagulant tanks approximately 5 – 6 m in height to the North of the site adjacent to existing tanks that are larger in height. This is also due to run from April/May 2025 and last for around 12 months. This will be carried out by RSE

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? |
|
All the work will take place within and directly adjacent to our site boundary and will be undertaken by our supply partners Mott MacDonald Bentley (MMB) and Ross-Shire Engineering. We do not anticipate any disruption for you and, I just wanted to let you know that you may notice increased activity and more heavy vehicles movements from the site but with mitigation in place with vehiclular movements avoiding the village, as well as a little more noise from the site. |
|
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. For notifications about project news, traffic information and progress updates please sign up to the Community Portal by clicking on the 'Follow this project' button above. 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 and Ross-Shire Engineering, experienced contractors 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 large 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. |
