BOURNEMOUTH Water has started a major £85 million upgrade to its Knapp Mill Water Treatment Works in Christchurch. 

The project is part of a £200 million investment by the water company to upgrade its main treatment works with state-of-the-art technology. 

The upgrades promise to add “industry-leading” treatment technology to existing processes to ensure safe drinking water in the future.

They were designed by Bournemouth Water's expert teams alongside its delivery partners.

Initial preparatory work has now started at Knapp Mill, with full construction due to begin next month.

The upgraded treatment works are expected to become operational in 2026 while maintaining normal operations throughout the construction period. 

Around 200 jobs are planned to be created during the work, providing high-skilled employment opportunities within the local area. 

Richard Stanbrook, general manager of drinking water services at Bournemouth Water, said: “We’re excited to get work underway at Knapp Mill as part of the major investment we’re making to upgrade our main treatment works in Bournemouth and Christchurch. 

"Both Mike [Hall, senior production technician at Bournemouth Water] and I have over 67 years of service together and this is a step change we have looked forward to.  

“By investing in these cutting-edge treatment technologies now, we’re ensuring our water network is fit for the future, while also creating jobs and supporting the local economy.” 

As well as this, Bournemouth Water said the project will help boost biodiversity thanks to improved landscaping around the Knapp Mill site, which will support wildlife and enhance the natural environment along the River Avon. 

The improved treatment process will also eliminate yellow water some residents have previously noticed in the colour of their water in the past following heavy rainfall. 

Residents are invited to drop-in sessions with the company’s experts at Furlong Shopping Centre, Ringwood, on October 24 from 12pm until 6pm.  

Work at the Alderney site, off Francis Avenue, started last year and is also progressing well with completion scheduled for next year, the water firm added.
