Norte Tangamanga II Wastewater Treatment Plant, San Luis Potosí, Mexico

Norte Tangamanga II is a wastewater treatment plant located in San Luis Potosí, Mexico, serving the city's municipal wastewater needs. The plant is situated in the Centro Histórico area and serves a population of approximately 71,626 people, placing it in the medium agglomeration category under Mexican water management frameworks. As a Mexican wastewater facility, Norte Tangamanga II operates under the national regulatory framework overseen by CONAGUA (Comisión Nacional del Agua), which sets discharge standards and water quality criteria. Plants serving populations of this scale are typically required to provide at least secondary treatment to meet environmental standards for receiving water bodies. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Pánuco River basin and flows toward the Gulf of Mexico. This region faces water quality challenges due to industrial and urban runoff, making effective wastewater treatment critical for protecting downstream aquatic ecosystems and human health.

The plant discharges into the Pánuco River basin, which flows through central Mexico and empties into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. Effective treatment is essential to prevent nutrient loading and contamination that could harm the sensitive coastal ecosystems of the Gulf.
