Bournemouth Water is making major progress on its £113 million upgrade at Alderney Water Treatment Works, part of a wider £200 million investment to modernise water infrastructure.

The project aims to secure long-term water supplies for over 250,000 customers while reducing environmental impact and improving climate resilience.

Water Minister Emma Hardy and Jessica Toale MP visited the site yesterday to review developments and see the new technology in action.

Emma Hardy said: “This is a welcome investment in securing clean, reliable water for the Bournemouth area.”

Work so far includes new treatment buildings, the installation of ceramic membrane technology, emergency power systems, and 70 modular filtration units.

Other improvements include new water pumps, upgraded pipework, a new chlorine storage facility, and a flow balance tank to support consistent treatment levels.

Ninety-five percent of the building cladding is now complete, making the site mostly watertight.

Once finished, the Alderney facility will deliver sustainable water through an upgraded, energy-efficient system.

Susan Davy, CEO of Pennon, said: “This multi-million-pound upgrade will deliver clean, reliable water to thousands of homes and businesses, while cutting carbon and boosting resilience.”

The Alderney scheme is one of the largest investments Bournemouth Water has made and is expected to be fully operational in the near future.
