The consultation window for phase three of the Cambridgeshire fenland reservoir is nearing its end on 10th December 2025, having been open since 15th October 2025.
The proposed reservoir has been designated by the Secretary of State for the Department for Environment, Food and Rural Affairs (DEFRA) as a Nationally Significant Infrastructure Project (NSIP) owing to its capacity being greater than 30 million cubic metres of water. The project requires a development consent order (DCO), the application for which is expected before March 2027.
The reservoir’s total capacity would be 55 million cubic metres and have a usable volume of 50 million cubic metres.
The East of England is both the driest and the fastest-growing region in the UK. From as early as 2036, the reservoir could supply 250,000 homes and help to alleviate the burden placed on existing water infrastructure. The project would theoretically protect sensitive resources such as chalk streams, increasing climate resilience.
As part of the scheme, it is estimated that 500 hectares of wetland and open space could be created alongside 35km of active travel routes.
Proposals indicate that the site could become a destination for 400,000 visitors per year, featuring water sports and other touristic activities. The recreational hub would be accessible from the A141 as well as from neighbouring Wimblington and Doddington.
