Caesb Water Network Pressure Telemetry

Caesb, the Federal District's publicly owned water and sanitation company, began fitting wireless sensors to the control valves on its main distribution networks in November 2023, under a R$5.2 million contract covering 754 measurement points. The readings are watched from the control rooms of Caesb's Centro-Norte and Oeste-Sul network operation and maintenance superintendencies, and the diagnostic is simple: if flow rises while pressure falls, that indicates a burst; if pressure is uniformly low, an area is about to run dry. By May 2024, 378 of the 754 points had been installed — half the contract — and the company said the rest would follow by that July. The telemetry sits on top of a longer loss-reduction programme financed with a R$170 million Inter-American Development Bank loan, which sectorised the distribution network into metered control districts, georeferenced the pipe register and put pressure-reducing valves under remote control. A separate and earlier Caesb programme put IoT consumption telemetry on the meters of large customers from 2019; that is a different contract with a different purpose.
