Ecatepec mayor asks Supreme Court to modify costly water‑supply amparo

The municipal government of Ecatepec, Mexico, petitioned the Supreme Court of Justice of the Nation (SCJN) to suspend or modify the public resolution of amparo case 13/2026. Mayor Azucena Cisneros Coss argued that complying with the proposed measures would require more than six billion pesos, a cost she described as technically and financially unviable.

Cisneros detailed recent improvements to the city’s water system, including rehabilitation of wells, main distribution networks, construction of the Tanque Maestro in Ciudad Cuauhtémoc, leak repairs and anti‑theft actions. The resolution calls for installing water meters in the Quinta Zona (about 682,000 residents) at an estimated cost of two billion pesos, and upgrading hydraulic infrastructure to meet the NOM‑127‑SSA1‑2021 water‑quality standard at an additional four billion pesos. The mayor noted that many obligations are already being met, such as daily water deliveries of 100 liters per household via tankers and expanded network coverage.

She requested that the court either remove the immediate requirement to comply with the NOM‑127‑SSA1‑2021 norm or grant a twelve‑month period to begin implementation, citing the historical lack of maintenance and the financial strain on the municipal budget.
