Contracts signed and value contracted under each code, counted from Portugal's open register across every procedure type. Each row is the deepest code carrying data, because a whole division is credited with everything beneath it and would take the list.

## What the notices look like

These contracts are long and recurring, which means the incumbent advantage is real and the re-tender date is the opportunity. The notices themselves are often mundane; the money is in multi-year service contracts renewed on a known cycle.

## Who publishes these tenders

The registry classifies buyers by type (health, state enterprise, regional, defence, donor) and this sector is not one of those types, so no sector-buyer count is published here. Its notices come from the general public buyers of each country; the country pages show where those publish.

## Frequently asked questions

**Which CPV codes cover water and waste tenders?**

Water and environmental procurement runs under CPV division 90, sewage, refuse, cleaning and environmental services, and division 41, collected and purified water, with treatment and network construction procured under the construction divisions. Equipment for treatment plants appears under the industrial machinery codes, so the sector's real footprint is wider than its two headline divisions.

**Who publishes water and waste tenders?**

Usually the operator rather than the state: municipal water companies, regional utilities and waste authorities, most of them publishing on their own channels alongside the national portal. In the TRINTA registry these appear as state-owned enterprises and regional buyers, the two largest categories of source outside the national channels.

## How contested it is, measured in Portugal

- 7.6% of open procedures drew a single bid
- 7.1 bids on average
- 607 open procedures behind these figures
- CPV 90, Sewage, refuse, cleaning and environmental services: 7.6% single bid across 607 procedures

Portugal publishes its complete contract register as open data, so competition is counted there rather than estimated. These are Portuguese figures for January to July 2026, covering only open procedures whose bidder list was reported; direct awards are excluded, because there the buyer chooses who bids.
