Fraccionamiento URBI Wastewater Treatment Plant, Tonalá, Jalisco, Mexico

Fraccionamiento URBI is a municipal wastewater treatment facility located in Tonalá, within the state of Jalisco, Mexico. The plant serves a population of approximately 9,127 residents, classifying it as a small to medium agglomeration under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required for urban wastewater in Mexico under the official standard NOM-001-SEMARNAT-1996. With a designed capacity of 864 cubic meters per day and a discharge volume matching that figure, the facility 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 Santiago River basin. The Santiago River flows westward through Jalisco and eventually reaches the Pacific Ocean near San Blas, Nayarit. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this region.

The plant discharges into the Santiago River basin, which flows through the state of Jalisco and empties into the Pacific Ocean. The downstream environment includes the Santiago River, which supports diverse aquatic life and is used for irrigation and recreation. The region's semi-arid climate and growing urban population make effective wastewater treatment critical for maintaining water quality and ecological balance in the watershed.
