The Hinckley to Hartshill Project forms part of Severn Trent Water’s proposals to decommission its Hinckley Sewage Treatment Works and transfer all sewer flows to its upgraded facility in Hartshill, about 12.5 km north-west of the site.

The transfer will be through a new pipeline route, part of which consists of gravity sewers up to 1050 mm in diameter and in the form of parallel rising mains. The new sewer system will be predominately constructed using a cut and cover approach. At locations where the sewer crosses key third-party assets, trenchless methods were designed. This includes pipe jacking up to 1500 mm internal diameter under Network Rail, Highways England, Environment Agency and Canal & River Trust assets.

The project also includes two major pumping stations with transfer flows up to 430 L/s and associated offline storage of 1600 m³. Resilience is a key design requirement to provide environmental safety and to accommodate climate change. In addition, the project includes full environmental and planning consents with a biodiversity net gain over 15% provided for. The project commission includes all civil, structural, hydraulic, geotechnical, electrical, mechanical and ICA design, as well as all relevant planning, sustainability and environmental consents.
