The Northumbrian Water scheme to upgrade Horsley water treatment works, which was built in the 1970s and is nearing the end of its design life, is to begin this month.

The site serves 800,000 customers on Tyneside and can treat up to 150 million litres of water a day.

The major two-and-a-half year programme of work has been awarded to Doosan Interserve - a joint venture involving Interserve, the FTSE-listed construction and support services company, and Birmingham-based process engineering company, Doosan Enpure. It will involve building new treatment facilities alongside the current plant, which will continue to operate until the new works is complete.

Customer’s water supply will not be affected while this work is carried out.

Northumbrian Water is working with contractors and supply partners to ensure that, where possible, site traffic uses Styford roundabout on the A69, which will be signposted, rather than travelling through Horsley village.

The new design re-uses some of the existing structures and the remainder will be demolished once the new works is fully operational. Most of the spoil that is excavated as part of the project will be re-used on site, rather than removing it using heavy vehicles.

Noel Cooper, Northumbrian Water’s Head of Water Supply, said: “We are committed to providing our customers with unrivalled customer experience. We know how much our customers rely on their tap water so ensuring it is excellent quality is a top priority.

“This work will not only ensure that the Horsley water treatment works continues to meet ever increasing water quality standards, it will also improve the site’s resilience. I would like to assure the local community that we will do our best to keep disruption to a minimum and we thank them for their patience while this essential work is carried out.”

Sean Brown, Doosan-Interserve’s project manager for the scheme, said: “Both Interserve and Doosan Enpure have an established track record of delivering major utilities projects and we’re excited to be working together on this project for Northumbrian Water which will give the residents of Tyneside a world-class facility that will be used for years to come. Where possible, we will use local resources, while supporting the local economy and employment in the region.”

Untreated water for the Horsley works comes from the River Tyne at Ovingham and the Whittle Dene complex of reservoirs. The treated water supply from Horsley, which also serves the village of Horsley, together with additional water from the treatment works at Whittle Dene, supplies the drinking water for Tyneside.
