Rastro Municipal Wastewater Treatment Plant, Villa Victoria, Estado de México

Rastro Municipal is a wastewater treatment plant located in Villa Victoria, Estado de México, Mexico. The plant serves a small community of 365 people, reflecting its role in managing local domestic wastewater in a rural or peri-urban setting. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. Under Mexican regulations, wastewater treatment plants are governed by NOM-001-SEMARNAT-1996 and subsequent standards, which set discharge limits for pollutants based on receiving water body type. The plant's designed capacity of 172.80 m³/day indicates it is sized for modest flows, with current discharge volume at 34.56 m³/day. The plant discharges treated effluent into local watercourses that ultimately drain into the Lerma River basin, a major watershed in central Mexico. The Lerma River flows into Lake Chapala, Mexico's largest freshwater lake, which supports diverse aquatic life and provides water for irrigation and human consumption. Proper treatment at plants like Rastro Municipal helps protect downstream water quality and ecosystem health.

The plant's treated effluent enters local streams that are part of the Lerma River basin, which drains into Lake Chapala. This watershed supports a variety of aquatic species and is an important water source for agriculture and communities downstream. Protecting water quality in this basin is critical for maintaining ecological balance and human uses.
