Anglian Water’s @one Alliance is due to begin work upgrading its Water Recycling Centre (WRC) off Tenpenny Hill in Thorrington, installing new equipment which will remove phosphorous from wastewater, improving river water quality nearby.

Phosphorous is widely used in soaps and cleaning products but can be harmful to wildlife when it reaches rivers and other watercourses. The investment at Thorrington’s WRC, which is worth over £4 million, includes new equipment to strengthen the current water recycling process and remove even more phosphorous from wastewater. This equipment will help remove harmful algae growth and improve water quality in local watercourses.

Work will start on site this month and is expected to finish by autumn 2024. As the upgrades are taking place on site at the WRC, Anglian Water customers in the local area should not experience any disruption during the scheme.

Anglian Water’s team has used detailed modelling of the local system to design a robust engineering scheme which will help to protect local watercourses in the Essex area now and in the future. This investment means the water entering Tenpenny Brook from Thorrington’s WRC will be even cleaner, protecting wildlife and water quality in the river.

Regan Harris, spokesperson for Anglian Water, said: “We’re really pleased that these upgrades to our Water Recycling Centre in Thorrington will help to protect nearby rivers and increase our resilience to climate change, by helping us make sure the wastewater is treated to an even higher standard than usual before it’s returned to the natural environment.

“We know how important rivers and the wider environment are to our customers and local communities. That’s why we’ve committed through our Get River Positive programme that our water recycling processes will not harm rivers.”

Get River Positive was launched by Anglian Water and Severn Trent in 2022. The plan includes five pledges to transform river water quality across their regions and demonstrates a clear and actionable response to calls for a revival of rivers in England. Central to the pledges is a commitment that work carried out by the two water companies will ensure storm overflows and sewage treatment works do not harm rivers.

This project will be completed by Anglian Water’s @one Alliance. The @one Alliance delivers complex engineering and construction projects across the Anglian Water region, utilising the skills and expertise provided by their seven partner organisations – specialising in the world of water.
