Portsmouth Water is planning to create a new reservoir in Hampshire to secure reliable drinking water for years to come.

The reservoir would be built on the grassland site next to Havant Thicket, which sits in between Rowlands Castle, Leigh Park and Staunton Country Park in Havant.

As well as providing reliable supplies for the water-stressed South East, it would also create a new green, leisure facility for local communities.

It would be the first new reservoir to be built in the South East since the 1970s and is being developed in collaboration with Southern Water.


Planning permission for Havant Thicket Reservoir

On 9 June 2021, East Hampshire District Council’s Planning Committee resolved to grant planning permission for Havant Thicket Reservoir.

The decision came after councillors in neighbouring Havant Borough gave their support to our reservoir proposals on 3 June 2021, along with our plans for a reservoir pipeline.

The next step is for legal commitments to be finalised with the local authorities, before full planning permission is granted, potentially this summer. The reservoir is due to be completed and operational by 2029.
