The utility has been cutting its network into metered sectors and has finished 484 of them, 58 percent of the plan. It still loses around 40 percent of its water, and the promised public dashboard never appeared.

Mexico City's water utility has been carving its distribution network into roughly 830 metered sectors since 2019, fitting macro-meters, control valves and pressure regulators so leaks can be isolated and pressure managed. It reported 484 sectors finished by August 2022, 58 percent of the plan, and the goal of covering the whole city by 2024 was missed. Telemetry and SCADA stations watch wells, tanks and pumping plants, and residents can look up their neighbourhood's water source and rationing schedule online. What the city does not publish is the measurements themselves: a promised public dashboard of network readings, due at the end of 2022, never appeared.

Live 📅 since 2019

📊 Impact

484 of 847 planned hydraulic sectors were built by August 2022 — 58 percent of the programme by the count in La Razón's report of the utility's progress; most other sources put the plan total near 830 — for 955.5 million pesos, which the utility credited with recovering 550 litres per second across seven boroughs. Sacmex has repeatedly put losses at around 40 percent of supply. A 2023 PLOS Water study surveying 2,595 residents found 73 percent of households in the five eastern boroughs receive water only intermittently, averaging 87 hours a week, and 61 percent had suffered an outage in the previous three years.

🎓 Lesson

Cutting a network into metered sectors only pays if the sectors are then operated and the readings are published. Mexico City has built more than half of them, still loses roughly 40 percent of its water by its own account, and gives residents a schedule lookup instead of the data.
