Water supply infrastructure

Water stored at the reservoir will need to be treated ready for public supply, before being transferred into supply.

Treating the water

A new water treatment works will make the water safe for people to drink. This facility includes screens to filter out debris from the water, equipment to remove impurities from the water by adding solutions that make these particles bigger, and then more equipment to filter the particles out through different screens and materials. The filtered water is then cleaned to make it safe to drink, before being transferred to homes and businesses.

Supplying treated water

Our draft Water Resources Management Plan 2024 identifies where the treated drinking water should be sent to, for supplying to homes and businesses via our existing network of pipes. The treated water will be transported to each place via a new underground pipeline.

We've identified the following water supply infrastructure that would ensure clean water reaches our customers' taps.

Through our assessments, we’ve identified a preferred area of land within which we could build a water treatment works. This area of land is south of the reservoir by the A52, between Swaton and Spanby.

Wilsthorpe connection point

We'll transfer treated water from the reservoir to customers via an underground pipeline. Our proposals involve a pipeline that's approximately 30 kilometres in length, travelling to a service reservoir just west of Thurlby in South Kesteven.

Chesterton connection point

To connect to our supply point at Chesterton, we're proposing to build an underground pipeline from Wilsthorpe that would be approximately 25 kilometers in length, running southwards to a new service reservoir west of Peterborough.

Have your say

The phase two consultation is open from 30 May until 9 August 2024.

Your local knowledge is valuable to us, and we welcome any feedback you have on our proposals for the associated water infrastructure.
