Installation of the replacement pipeline will likely take place in May and June 2022.

Construction updates will be provided to the local community at least two months before the installation works commence. We will agree how we communicate this information with local authorities.

The map above provides information on installation within the SANG. As outlined in the planning process, the project will be narrow working through the SANG. Further information on our construction plans can be found below.

About installation

Where required vegetation and tree clearance will be undertaken by a small team during March 2022.

Before installation starts, the first thing you will see is signs notifying SANG users that works will be taking place.

When installation starts, Heras-type fencing bolted together, or strong-wall fencing, will be used to secure the working area.

You may also see mobile welfare units, equipment, materials and vehicles within the working area.

During the open cut installation process, you may see deliveries of the steel pipes. These will be brought to site in a ‘just-in-time’ delivery sequencing. We will also have 24-hour security of the working areas within the SANG.

Access to Windlemere SANG will be available throughout installation. If there are any areas of closure, including footpath diversions, we will notify the community in advance.

The car park used for Windlesham SANG will not be impacted by the works.

Our work in the SANG will require some vegetation clearance, including shrubs and some younger trees. We will replace any trees we need to remove.

We will likely be using an auger bore to install under Lightwater Bypass / A322. These works will likely take place in May and June 2022.

This work will take place at the same time as the open cut installation work through the SANG.

We have thoroughly surveyed the ponds in Windlemere SANG for Great-Crested Newts. To protect them, we will put up fences and move them out of the working area before installation starts under a licence from Natural England.

Vegetation

Where the topsoil has been stripped and stored, this will then be replaced after the works have been completed and either reseeded or left to naturally regenerate, following discussion with Surrey Heath Borough Council.

The vegetation reinstatement will be subject to a five-year aftercare.
