What is being bought

Published requirement description

Supply (including design, assembly, supply, delivery and co-commissioning) of an integral modular primary and secondary treatment system(s) to be implemented as sidestream solutions at multiple sewage treatment works (STWs) across AMP8.

Severn Trent Water requires integral solutions - primary settlement, biozone/ biological treatment and humus/ final settlement - all to be contained within a singular modular 'roll on roll off' unit - with lifting points for cranage where required.

Potential for a limited number of alternative configuration units may be required depending on site requirements - e.g.) biozone only, biozone + humus settlement zone, primary settlement + biozone.

The units required are to be deployed at small to medium size treatment works. With the aim being to install an independent side stream to increase the treatment capacity. Allowing for an increase of Flow to Full Treatment (FFT). The flow will be proportionally distributed between the existing assets and modular sidestreams based upon the maximum treatment flow.

  • Solution can be either SAF or MBBR
  • Automated sludge removal is to be provided from the humus and primary zones.
  • Adjusted aeration is to be provided to the biological treatment zone, to allow for optimisation and scouring (as required).
  • Lamella units are not a preferred settlement process (for primary or humus), due to previous operational issues requiring excessive operational intervention.

Question for the bid
This buyerSEVERN TRENT WATER LIMITED · all categories
What to do with it
How often do SMEs win?
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.

Last 36 months.

Buyer: 4 of 20 known-size awards · market: CPV 4461 · UK-wide, n=10
20%100%

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
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.

Last 36 months.

Buyer: 15 of 17 known-location awards · market: CPV 4461 · UK-wide, n=15
88%27%

Most of this buyer’s recorded winners are registered in West Midlands.

How long to a decision?
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.

Last 36 months.

Buyer: 15 decided notices · market: division 44 · UK-wide, n=46
146 days77 days

Half of these awards were announced within 146 days of the bid deadline.

How often single-bid or direct?
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.

Last 36 months.

Buyer: at least 1 of 15 procurements with awards had no recorded rival · market: CPV 4461 · UK-wide, n=8
7%13%

Missing bid counts may hide more single-bid awards. This share is a minimum.

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.

Past bids do not predict this tender.

How did awards compare with estimates?

i

Where winning prices landed against estimates.

Each colour shows awards below, close to or above the published estimate, one lot at a time.

On a framework or DPS, prices are agreed when work is called off.

Past prices are a guide, not a bid price.

Last 36 months.

Not comparable on a framework or DPS. The notice sets up a supplier panel and a ceiling value; what the work actually costs is agreed later, on each call-off or mini-competition, and those publish as contract notices of their own. The award-vs-estimate record of this market therefore sits on the call-offs; this page shows it on the contracts, not on the panel that frames them.

How many bids this lot may attract.

The forecast uses similar past competitions. The bar shows either that forecast or past bid counts; the line below says which.

Each lot shows its own forecast based on its own category; forecasts for different lots of the same notice are not comparative. The bar shows 26 past lots.

Commercial price forecast
i

Where the award price may land.

The forecast uses similar awards and the buyer’s estimate. The band covers the middle half of likely prices.

No comparable awards for this lot yet.

A statistical guide from past awards, not a price to bid.

—Priced at call-off
On a framework or DPS the price is agreed on each call-off, so there is no award price to forecast here: the published figure is a ceiling.

Who has supplied this buyer on similar work?
i

Who has done similar work for this buyer.

Past contracts are matched by buyer, title and type of work.

A past supplier may not bid again.

No earlier contract of this buyer matches this lot on the published record.

Who could compete for this lot?

Who could compete for this lot?

Firms with relevant past wins. On a framework, we show firms on that agreement.

None is confirmed as a bidder.

Candidate suppliers for this notice have not been worked out yet, so this is not a verdict that nobody fits.

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.
