Rastro is a municipal wastewater treatment plant located in the Santa Fe neighborhood of Zapopan, within the Jalisco region of Mexico. The facility serves a population of approximately 4,564 residents, classifying it as a small-scale treatment plant under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard biological treatment required by Mexican environmental law (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 432 cubic meters per day and a discharge volume matching that figure, the plant operates at full capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Santiago River basin. This region is part of the Lerma-Chapala-Santiago hydrological system, one of Mexico's most important water systems, supporting diverse aquatic life and agricultural activities downstream.
Environmental context
The plant's discharge enters the Santiago River watershed, which flows through Jalisco and empties into the Pacific Ocean near San Blas, Nayarit. This basin supports a variety of aquatic species and is used for irrigation and recreation. The downstream environment includes the Santiago River, which is ecologically sensitive due to industrial and agricultural runoff from the Guadalajara metropolitan area.
