What is being bought

Southern Water is advancing two strategic water recycling schemes, Medway and Littlehampton, to deliver up to 33.4 million litres per day of purified recycled water during drought conditions. These schemes will reduce abstraction from sensitive river systems, support environmental destinations, and ensure resilient water supplies for future generations. The Projects respond to Environment Agency directives to reduce abstraction and to regional forecasts of supply deficits under Water Resource South East (WRSE) and Water Resource Management Plan 2024 (WRMP24) planning scenarios. The schemes are essential to meeting Southern Water's obligations under the Water Industry National Environment Programme (WINEP) and are expected to contribute to achieving environmental destination outcomes in sensitive catchments.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 45. The category anchor is Water-treatment work (45232430); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 4510,6484 median · 26 average (2,824 of 10,648 with a bid count)3.7 average (3,104 of 10,648 with named award suppliers)Not published
Same buyer8Not publishedNot publishedNot published

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
