Asset Optimization Secures 40% Cost Saving and Contract Award at Leicestershire STW Project
Barhale and Severn Trent have collaborated to unlock a £2M saving on the Ravenstone Sewage Treatment Works upgrade through early contractor involvement (ECI). Following the successful ECI, civil engineering, infrastructure and tunnelling specialist Barhale has been appointed to deliver the main works design and build contract. Rather than constructing new assets, the scheme will refurbish and optimise existing infrastructure. Severn Trent Water identified the need for an upgrade at Ravenstone after close monitoring of dry weather flows over a six-year period. The scheme will increase the STW’s hydraulic and treatment capacity while also tightening final effluent standards, including meeting the requirements of a new ammonia permit. During ECI, Barhale carried out hydraulic assessments to understand how the existing assets could perform. This work showed that key structures could be retained, removing the need for additional construction and reducing mechanical complexi...
