BCS - Construction of the Havant Thicket Reservoir

Havant Thicket, the first reservoir to be built in the South East since the 1970s, includes the project, history, and environmental focus.

The reservoir is an environmentally-led project that will help to safeguard internationally-rare rivers in Hampshire by providing an alternative and sustainable source of water.

Havant Thicket is the first new reservoir to be built in the South East since the 1970s and is being developed in collaboration between Portsmouth Water and Southern Water. Portsmouth Water have been supplying water to Portsmouth and the surrounding area since 1857.

The area supplied by the Company extends through South East Hampshire and West Sussex from the River Meon in the West to the River Arun in the East, encompassing 868 sq. kilometres.
