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
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

src-bc2f84a67e939c1f'Se han concluido 484 de los 847 sectores' previstos para 2024, con una inversión de 955 millones de pesos ('484 of the 847 sectors planned for 2024 have been completed', 955 million pesos invested). Same piece: 'Para finales de ese año se preveía un portal de acceso público con mediciones principales de la ciudad' ('a public portal with the city's main measurements was expected by the end of that year') — that portal was not found in 2026. Most other sources give the plan total as 830, not 847.
src-eede65a00950007fDates the start of the programme to 2019, beginning in Álvaro Obregón and Benito Juárez under that year's Sacmex works plan. Basis for yearStart.
src-f0196077f3db909f'Rehabilitación de 35 estaciones de medición y telemetría, así como la implementación de 30 nuevas estaciones' ('rehabilitation of 35 measurement and telemetry stations, plus 30 new stations'), a 30 million peso investment permitting real-time monitoring. The same article's figure of 9,270 litres per second recovered covers wells, springs and pumping plants generally and is deliberately not used here.
src-524a22a68aa0009419 billion pesos for water and drainage in 2026, an increase of 26.7 percent; the works contemplate 'medición, automatización y telemetría' to 'incrementar la eficiencia de la infraestructura hidráulica' ('metering, automation and telemetry' to 'increase the efficiency of the hydraulic infrastructure'). Evidence the programme is still live and funded.
src-d0eb02f88a03520a'Triplicar la reparación de fugas, lo que permitiría recuperar 300 litros por segundo' ('triple leak repairs, which would allow 300 litres per second to be recovered') and 'inteligencia satelital y georradar terrestre, capaces de supervisar 800 kilómetros de infraestructura subterránea' ('satellite intelligence and ground-penetrating radar, able to survey 800 kilometres of underground infrastructure'). Strongest recent source on current state.
src-08385970aaf20ab7Public lookup returning a neighbourhood's water source and scheduled supply hours. The page is a JavaScript single-page app and served no readable content to an automated fetch; existence and function corroborated by press coverage below. It publishes schedules, not measurements, and offers no download or API.
src-54501ed7544594a3Independent corroboration of what the portal does: select borough and neighbourhood to get the water source and the hours when supply is scheduled.
src-3bf462f37ab09e44'CdMx pierde 40 por ciento de agua por fugas en redes, revela Sacmex' ('Mexico City loses 40 percent of its water to network leaks, Sacmex reveals'). The figure is the utility's own, reported consistently by El Universal, Crónica and Aristegui Noticias since 2015; it is attributed here rather than asserted. Note: the city's own indicator portal (indicadores.cdmx.gob.mx) is reported to record 52.19 percent unaccounted-for water for 2022, a materially higher figure, but that page returned HTTP 503 on every attempt during review and the number is therefore not used.
src-c91cdcc8f0181e59Peer-reviewed. '73% of surveyed households in those five boroughs reported receiving water intermittently', 'with an average of 87 hours a week, or roughly 12 hours a day'; '61% of surveyed households reported having experienced an outage of their water supply in the last three years'. Survey of 2,595 individuals in Gustavo A. Madero, Venustiano Carranza, Iztacalco, Iztapalapa and Tláhuac.
src-b02c2cfc68dbfd13'Con 65 votos a favor se avalaron cambios al Artículo 16 de la Constitución capitalina' so that 'el Sistema de Aguas de la Ciudad de México (Sacmex) pasará a ser la Secretaría de Gestión Integral del Agua' ('with 65 votes in favour, changes to Article 16 of the city constitution were approved' so that Sacmex 'will become the Secretariat for Integrated Water Management'). The change was completed in December 2025; Segiagua is the operator today, Sacmex the name under which most of this work was done.
