Mexico's national water authority Conagua has signed an agreement with the Puebla and Tlaxcala state governments to improve wastewater treatment coverage and overall environmental standards.
The agreement, which will require at least 365mn pesos (US$31.5mn), aims to clean up the Atoyac Zahuapan basin, rivers Zahuapan, Atoyac and Alseseca, and the Manuel Ávila Camacho reservoir, also known as the Valsequillo reservoir, benefiting some 70 municipalities.
Work includes repairing and expanding four wastewater treatment plants in Puebla, increasing wastewater treatment in the state to 3.1m/s, treating 90% of the wastewater which is currently channeled into the Valsequillo reservoir. The project will cost 185mn pesos.
Conagua will also build four new wastewater treatment plants in Tlaxcala, each with capacity to treat 220l/s, at a total cost of 180mn pesos, according to a Conagua release.
The project falls under the national government's 2030 water plan, which focuses on cleaning rivers, stabilizing basins, flood relief, and reaching universal potable water coverage.
