Hampshire Water Transfer and Recycling Project - Design, Build, Finance, Maintain and Operate Contract

Southern Water is seeking a Competitively Appointed Provider (CAP) to deliver the Hampshire Water Transfer and Water Recycling Project (HWTWRP), a major water infrastructure initiative addressing supply shortfalls in Hampshire. This Design, Build, Finance, Maintain and Operate (DBFOM) project will create a sustainable water supply by treating wastewater into purified recycled water and transferring it approximately 42 km to Otterbourne Water Supply Works. Key project components include a water recycling plant, tunnelling works (circa 42 km), pipeline and tunnel connections, a high lift pumping station, intermediate pumping stations, and break pressure tanks. The recycled water will be combined with natural spring water from Portsmouth Water's Bedhampton Springs and stored in the new Havant Thicket Reservoir before treatment to drinking water standards. This strategic resource option will enhance water resilience, improve drought preparedness, and reduce environmental impact. The project will be procured through Ofwat's Direct Procurement for Customers (DPC) model with an open tender process. Suppliers should note that not all referenced CPV code activities may be included in future tender notices.
