Kier's Natural Resources, Nuclear & Networks division has been awarded a £20.9 million AMP8 contract by Severn Trent to design, construct and commission major upgrades at the company's Worcester Sewage Treatment Works.
The project to increase the plant’s capacity and reduce storm overflows 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.
The upgrades will improve operational efficiency, support environmental sustainability, and ensure compliance with 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.
Rob Campbell, operations director for Kier Natural Resources, Nuclear & Networks commented:
"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."
Kaung Set Thar, Severn Trent Water Project Manager added:
“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.”
The project strengthens Kier's long-standing partnership with Severn Trent, having successfully delivered vital water infrastructure improvements for them over the past 20 years.
The contract award also builds on Kier’s proven expertise in the water sector, supporting the delivery of resilient and sustainable infrastructure.
Kier continues to be a trusted partner in the industry, recently securing appointments to Yorkshire Water’s £850 million Complex Non-Infrastructure Works Framework and Southern Water Services’ £3.1 billion Strategic Development Partnership Framework.
