State of Mexico expands sustainable water treatment with new facilities

The municipal government of Tecámac in the State of Mexico is operating six wastewater treatment plants that produce high‑quality reclaimed water, aiming to secure Zero‑Discharge certification from the national water commission. If approved, the municipality could receive up to 31 million pesos in annual discounts for discharge fees, funds it plans to use for a new drinking‑water plant. The facilities treat roughly 20 million cubic metres of water each year, recharging aquifers and supporting a local lagoon and artificial wetland.

In Toluca, the Organismo Agua y Saneamiento (OAyST) marked its 46th anniversary, highlighting financial self‑sufficiency and a historic increase in water‑service revenue. Under the 2025‑2050 Water Plan, the agency has completed about 130 infrastructure works, brought 16 of 21 new water sources into operation, rehabilitated 28 wells, and recovered a flow of 675 litres per second, improving supply for thousands of households.
