Rastro Municipal Wastewater Treatment Plant, Amanalco de Becerra, Estado de México

Rastro Municipal is a wastewater treatment facility located in Amanalco de Becerra, within the Estado de México region of Mexico. The plant serves a small population of 383 residents, reflecting its role in a rural or semi-urban community. It is situated inland, far from coastal areas, and its operations are part of the local municipal infrastructure. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 86.40 units and a current discharge volume of 36.29 units, the facility operates below its full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and the Federal Law for the Prevention and Control of Environmental Pollution, which set effluent quality standards for discharge into water bodies. The treated effluent from Rastro Municipal is discharged into a local water body, likely a river or stream within the Lerma River basin, which ultimately drains into the Pacific Ocean via the Lerma-Santiago system. The plant helps protect downstream aquatic ecosystems and supports water quality in the region, which is important for agriculture and local biodiversity.

The plant discharges into a local water body within the Lerma River basin, which flows into Lake Chapala and then the Santiago River before reaching the Pacific Ocean. The downstream environment supports diverse aquatic life and is used for irrigation, making effective treatment essential to prevent nutrient pollution and protect ecological health.
