A proposed new reservoir in Lincolnshire
Anglian Water is proposing a new reservoir in Lincolnshire to help meet the growing demands on water supply in the East of England.
The new reservoir is at the heart of a whole new water supply project. Together with the associated water infrastructure we need to transfer water to the reservoir, and from the reservoir to homes and businesses, it will secure a reliable water supply for generations to come.
We understand that our proposals will have an effect on landowners, homeowners, and nearby communities, and are committed to working with everyone as the project develops.

We’ve been developing our proposals for a new reservoir in Lincolnshire and its connecting infrastructure. We’re currently planning to hold a third phase of public consultation in Autumn 2026, and look forward to welcoming feedback from the community and other stakeholders later this year.
More information about the consultation, and what it will involve, will be available in due course.
Our ongoing survey work
We’re continuing our work to better understand the land we could be working on.
In 2025, we completed a range of non-intrusive surveys and ground investigations, and we will be doing more in 2026.
We’re committed to keeping the local community informed of our work.
Our survey fact sheet is available here. And you can read more about surveys here.

The main reservoir site
The proposed reservoir site, south-east of Sleaford, about halfway between Grantham and Boston. We've now developed an emerging design with ideas for the features it might include, and have also provisionally identified areas of land to the north and south of the reservoir site that we could need for environmental mitigation measures and/or construction.
Associated water infrastructure
When there is available water in rivers that would otherwise drain to the sea, we would draw that water and transfer it to the reservoir using new and existing infrastructure and waterways. We've carried out multiple stages of assessment to identify areas of land within which the new infrastructure could be located to transfer water to the reservoir, treat it and then supply it to homes and businesses. The proposed locations are between Torksey, West Lindsey, Boston and south-west of Peterborough.
