Kier's Natural Resources, Nuclear & Networks division has been awarded a £20.9 million contract to design, construct, and commission significant upgrades at the Worcester Sewage Treatment Works on behalf of Severn Trent Water.

The project is designed to increase the plant's capacity, reduce storm overflows, and enhance the quality of life for local residents.

This contract is part of the Asset Management Period 8 (AMP8) investment cycle and reinforces Kier's two-decade-long partnership with Severn Trent in delivering vital water infrastructure improvements.

The scope of work for Kier includes the delivery of a new activated sludge plant (ASP) chemical dosing system, an additional final settlement tank (FST), and improvements to the sludge treatment process. These upgrades are intended to improve operational efficiency, support environmental sustainability, and ensure compliance with new phosphorus discharge permits.

Kier commenced Early Contractor Involvement (ECI) work with Severn Trent in March 2024 and is now transitioning into the full construction 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."

This contract award further solidifies Kier's expertise in the water sector, building on recent appointments to Yorkshire Water's £850 million Complex Non-Infrastructure Works Framework and Southern Water Services' £3.1 billion Strategic Development Partnership Framework.
