Águas Guariroba: Sectorised Network Telemetry and a One-Fifth Loss Rate
This overview was generated with AI from the public sources listed below and checked against them before publication. It has not had a complete human fact-check — treat it as a starting point and follow the sources.
How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page
Since taking over Campo Grande's water and sewerage concession in 2006, Águas Guariroba has run a loss-reduction programme built on a network data layer rather than on pipe replacement alone. The distribution network is split into virtual sectors so each block reports on itself; 197 network sensors track pressure, 185 modernised bulk meters measure what enters each sector, 62 pressure-reducing valves hold pressure down, and 381,800 household meters have been swapped. An operations control centre runs the Israeli TaKaDu software, in use by 2022, which flags anomalies — pressure swings, invisible leaks, supply interruptions — against expected network behaviour rather than waiting for a visible burst.
what does this mean?
The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →📊 Impact
Instituto Trata Brasil's Perdas de Água 2026 study, analysing SINISA 2024 returns with GO Associados, puts Campo Grande's distribution losses at 20.69% — third lowest of Brazil's 27 capitals, against a capital average of 39.30% — and 172.03 litres lost per connection per day against a capital average of 547.63. The operator reports the rate fell from 56% when it took over in 2006.
🎓 Lesson
The curve has flattened rather than continued down. Trata Brasil's earlier edition put Campo Grande at 19.74% on 2021 data; the 2024 data give 20.69%, and the concessionaire's own 2024 figure was 19.7%. After roughly fifteen years the sensor layer is maintaining a plateau at about a fifth of the water, not driving it lower — which is a different achievement from the headline reduction, and the one the city will have to defend against the 25% ceiling that national rules impose by 2033.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
