Severn Trent investing £17 million in projects across Chester 

30th October 2023

Multi-million pound projects are being planned throughout Chester which will help to ensure the future of the water network across the city and see big environmental benefits.

Severn Trent welcomed Dee Valley Water into the Severn Trent family in 2018 and took over operations in Chester. Since that time, it has already invested £4.5 million in the network through a series of works.

This investment included water pipe replacement and upgrades to the Boughton Water Treatment Works along with a project that has just been completed where £54,000 was used to fund the replacement of just under half a kilometre of mains pipes in Plemstall.

But there are some projects that have just started or are being planned for the next 18 months that will see a further £17 million of funding in schemes. 

These include the major £3.6m project on the River Dee to install fish friendly, eel screens on the river to protect local wildlife which began at the start of September and will be completed by March 2025.

The screens are being installed in raw water intakes where water is taken from before being turned into drinking water and will mean the different types of eels such as adult silver eels, yellow eels, juvenile glass eels and elver, as well as other types of fish and wildlife are protected.  
Other upcoming projects for the city are:

  • Manor Farm Close Water Quality Renewal – replacing half a kilometre of water main pipe in Mickle Trafford

  • Chester (Boughton WTW) Resilience – a new 600mm pipe to boost resilience at the water treatment works

  • Boughton WTW New Alum Tanks – a new system that will help improve water quality

Catherine Webb, Community Communications Officer at Severn Trent, said: “This investment and these projects are important pieces of work that will help with the resilience of our network and the work that we do for the city. Not only that, but our investments will also see us working to protect local wildlife, as well as have a positive impact on the customers that we serve, and providing a water supply, and network that’s fit for now, and future generations. We are looking forward to starting these works for the area and will reveal more details as soon as we can.”

Severn Trent customers in Chester receive a water-only service from the company, with around 100,000 customers in the city and 46,000 households. 

The water treatment works at Boughton, on the outskirts of Chester has been treating water from the River Dee and providing drinking water for the people of Chester for more than 160 years.
