Kier has won a £139 million contract with Severn Trent to upgrade Wanlip Sewage Treatment Works in Leicestershire.
Set to serve 750,000 residents, and designed to meet growing demand and tighter environmental standards, the project will significantly enhance treatment performance, improve water quality, and increase the site’s long-term resilience. Critically, the works will increase dry weather flow capacity by 24 per cent, and full flow to treatment by around 20 per cent.
Wanlip is Severn Trent’s third-largest wastewater treatment facility, and this flagship scheme forms a vital part of Severn Trent’s wider Green Recovery programme, reflecting the strength of a trusted relationship built over more than 20 years between Severn Trent and Kier.
Delivered in close collaboration with Severn Trent and specialist delivery partners, the project builds on a successful early contractor involvement phase, during which enabling works and detailed design development were completed.
The project will commence in summer 2025 and is planned to be completed in 2028.
Andy Lingham, MD of Water within Kier Natural Resources, Nuclear & Networks, stated: “This is a significant project for Severn Trent, and we’re pleased to be bringing our expertise to help deliver it. Our relationship spans more than 20 years, and this is one of many projects we’ll be delivering in this AMP8 cycle. Collaboration will be key to making it a success, with all parties co-located in our new welfare village, working together to ensure safe, efficient, and successful delivery.”
James Jesic, Capital Delivery and Commercial Director at, Severn Trent, said: “It’s exceedingly rare for us to award contracts of this size and it really speaks to the scale of these upgrades at Wanlip and our commitment to improving our infrastructure, delivering a reliable high-performing service for our customers, and protecting the environment.”
This contract award bolsters Kier’s presence in the UK water sector, following recent AMP8 contract wins and renewals with Yorkshire Water, Wessex Water, United Utilities, Southern Water, and Anglian Water.
