How this atlas is made · What “last verified” means

Sanepar and Stattus4 fitted AI-analyzed pressure sensors to water meters in a 22km pilot in Curitiba's Alto Boqueirão and Tatuquara neighborhoods to flag hidden leaks. From January-August 2023, Alto Boqueirão's loss rate fell about 69%, from roughly 650 to 200 liters/connection/day, and leak-investigation time dropped from up to 180 days to about three. Sanepar then contracted a 2,500km southern-Curitiba expansion.

📊 Impact

Alto Boqueirão's leak-loss rate fell about 69% (roughly 650 to 200 liters per connection per day) over the January-August 2023 pilot, per Sanepar and Stattus4's self-reported figures.

🎓 Lesson

A second pilot section in Tatuquara showed a comparable drop, but Sanepar's own releases give conflicting figures for it (41% vs. 49%), so only the better-corroborated Alto Boqueirão number is used here.

Sources

↗ Agência Estadual de Notícias do Paraná (state government press office)Direct fetch returned 404/blocked; content and figures confirmed via search-engine indexing and cross-matched against independent mirrors (saneamentobasico.com.br, saneparstartups.com.br). Covers the Jan-Aug 2023 pilot results and the 2,500km expansion contract.

↗ Saneamento Básico (trade press)Directly fetched. Confirms Alto Boqueirão 69% (650→~200 L/d), the 180-day-to-3-day leak-investigation improvement, and the two-year Startup Law contract for the 2,500km expansion. Gives Tatuquara as 49% (conflicts with the 41% figure attributed to the state government source).

↗ Stattus4 (vendor)Directly fetched, vendor's own account of the same pilot (described as Sector A/Sector B rather than by neighborhood name); confirms the ~70%/49% loss-recovery order of magnitude and the >2,500km 2024 expansion. Vendor source, used only to corroborate figures already found in press coverage.
