Official UK procurement notice
Existing Water Treatment Solutions
Authority: Mining Remediation Authority (Central government)
What is being bought
Published requirement descriptionThe Mining Remediation Authority (MRA) manages the effects of past coal mining, including managing mine water pollution from both coal and metal mines, handling subsidence damage claims which are not the responsibility of licensed coal mine operators, and managing other mining legacy issues.
The MRA seek to understand the current capabilities and limitations of, and opportunities presented by, treatment technologies used to remove saline and other mine water contaminants, opportunities for reducing or repurposing wastes, and opportunities for reducing the energy consumption of treatment plant. This will allow MRA to effectively plan future operational work such as purge- and pumping tests where treatment may be required and will potentially be used in the final design of long term MWTS.
More information on the scope requirements, procurement strategy and how to register your interest and information on the virtual event will be sent to interested parties on receipt of interest.

How Mining Remediation Authority buys Construction works for plants, mining and manufacturing and for buildings relating to the oil and gas industry (CPV 4525), and who usually turns up
Mining Remediation Authority’s own published record, next to the published market for the same work. Frameworks and DPS are kept out: they attract a different number of bids.

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 the winner is registered in the region where that contract was delivered.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside East Midlands.
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 118 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?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.

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.
