Southern Water Littlehampton & Medway Water Recycling Plants
Authority: Southern Water Services Limited (Public body)
What is being bought
Published requirement descriptionSouthern 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.

How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Here, local means registered in South East England (authority’s region).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside South East England.
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced within 79 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
Both shares are minimums: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
