Kier's Natural Resources, Nuclear & Networks division has been awarded a £20.9m contract to design, construct and commission major upgrades at the Worcester Sewage Treatment Works on behalf of Severn Trent Water.
The enhancements at Worcester will increase the plant’s capacity, reduce storm overflows, and improve the quality of life for local residents.
The project has been commissioned as part of the Asset Management Period 8 (AMP8) investment cycle, and strengthens Kier's long-standing partnership with Severn Trent, having successfully delivered vital water infrastructure improvements for them over the past 20 years.
The project will see Kier deliver essential enhancements, including a new activated sludge plant (ASP) chemical dosing system, an additional final settlement tank (FST), and improvements to the sludge treatment process.
These upgrades will improve operational efficiency, support environmental sustainability, and ensure compliance with the new phosphorus discharge permits.
Kier began Early Contractor Involvement (ECI) work with Severn Trent in March 2024 and is now transitioning into the build phase. The project is scheduled for completion in 2027.
"We are delighted to continue our longstanding partnership with Severn Trent through this significant upgrade to the Worcester Sewage Treatment Works. This project underpins our commitment to delivering essential infrastructure that enhances environmental sustainability and operational efficiency.
By leveraging our extensive experience and collaborative approach, we aim to ensure the successful delivery of these critical improvements for the communities we serve."
Rob Campbell, operations director for Kier Natural Resources, Nuclear & Networks
“This is a major investment programme for Worcestershire which we’re delighted to be delivering with our partners Kier.
Key benefits of the project will be to increase capacity and efficiency at the site, plus a reduction in phosphates in the final effluent before it’s released. That will help to further improve the health of our rivers.”
Kaung Set Thar, Severn Trent Water Project Manager
