Mexico's states grapple with water supply crises

In San Luis Potosí, the state water commission (CEA) distributed more than 30 million liters of drinking water by tanker trucks to neighborhoods where the Interapas supply system failed. Director Pascual Martínez Sánchez said the effort will continue while the intermunicipal service is repaired, and highlighted the El Peaje dam project, a new aqueduct and a potabilisation plant to diversify sources for the metropolitan area.

In Jalisco, legislator Mariana Casillas Guerrero warned that municipal water tests reveal heavy‑metal contamination and that the health secretariat has refused to issue a sanitary alert, calling the official monitoring “insufficient”.

The municipality of Ecatepec (State of Mexico) reported extensive infrastructure upgrades: five new or refurbished wells equipped with telemetry, a master storage tank over five million liters, and deployment of georadar and robots to detect leaks and illegal taps. The projects are part of a joint effort with the federal water agency (Sapase) to improve supply and curb water theft.

In Guanajuato, the municipal water‑service agency SIMAPAG completed urgent pipe‑replacement work at the La Soledad reservoir, using stainless‑steel clamps and neoprene sheets, after CONAGUA inspected a major underground leak. The agency plans similar repairs at other city reservoirs.

Elsewhere, Chihuahua’s health commission (Coespris) intensified campaigns for safe water consumption amid drought, while CONAGUA outlined a “plan B” to interconnect the San José and El Peaje reservoirs, which could raise capital‑area supply by about 20 percent.
