Campo Grande

Campo Grande has the third-lowest water losses of any Brazilian state capital, and the more interesting fact is that the curve has stopped falling. Since taking over the concession in 2006 the operator has built a network data layer rather than relying on pipe replacement alone: the distribution network is split into virtual sectors so each block reports on itself, with 197 network sensors tracking pressure, 185 modernised bulk meters measuring what enters each sector, 62 pressure-reducing valves and 381,800 household meters replaced, over an operations centre running anomaly-detection software that flags pressure swings and invisible leaks against expected behaviour. An independent study of 2024 national returns puts distribution losses at 20.69 per cent against a capital average of 39.30. An earlier edition of the same study put the city at 19.74 on 2021 data. After roughly fifteen years the sensor layer is holding a plateau at about a fifth of the water rather than driving it lower, which is a different achievement from the headline reduction and the one the city will have to defend against a national ceiling in 2033.

The bus fleet has reported its position since 2016, and the record it generated took nine years to bite. Every bus transmits from a control room the concessionaire runs inside the regulator's own mobility centre, and passengers see the same feed in an app covering 169 lines; the regulator reads it the other way round, booking a penalty notice whenever the start, the end or the whole of a scheduled trip goes unrecorded. A special municipal commission counted 21,910 such notices between 2021 and 2025, rising year on year, alongside an average fleet age of 7.6 years against a five-year contractual limit and a vehicle-inspection failure rate climbing from 5.4 to 18.6 per cent. In June 2026 the city placed the concession under intervention and removed the consortium's management. The same report lists the trackers, cameras and turnstiles among the equipment that was frequently defective — the sensors generating the compliance record are owned and maintained by the party being measured, so a missing trip and a broken tracker look alike in the data.

The two newest rooms show where a camera stops being a technical question. The mobility agency opened an integrated control centre in 2022 and rebuilt it at the end of 2025, taking cameras from 20 to 85 and putting about 200 signal sets on automatic fault alerts with remote re-timing, funded as a contract counterpart from the consortium that won the radar tender. Its most consistent measurable output is a maintenance queue: 2,048 signal-fault call-outs in 2025 and 348 records of theft, attempted theft and vandalism against signal equipment. Meanwhile the security secretariat's 112 downtown cameras include ten fitted for facial and plate recognition, and only the plate half works — the municipal guard holds no image database, so face matching would mean drawing on police records, which under Brazil's data-protection act requires a formal agreement that has not been signed. Two years on, the city states plainly that the system does not operate automatically. Reading a number plate touches no personal-data regime; reading a face does.
