Taxco de Alarcon Wastewater Treatment Plant, Taxco, Guerrero, Mexico

The Taxco de Alarcon wastewater treatment plant is located in Taxco, a historic city in the state of Guerrero, Mexico, known for its silver mining and colonial architecture. The plant serves a population of approximately 89,986 people, making it a medium-sized municipal facility that handles the domestic and commercial wastewater from the urban area. As a Mexican wastewater treatment plant, it operates under the national regulatory framework established by the Ley de Aguas Nacionales and the Normas Oficiales Mexicanas (NOMs), which set discharge standards for wastewater. For a plant serving nearly 90,000 people, secondary treatment is typically required to reduce organic matter and suspended solids before discharge. It is expected to meet the standards set by the Comisión Nacional del Agua (CONAGUA). The treated effluent from the plant is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Balsas River basin. The region's mountainous terrain and seasonal rainfall patterns influence the hydrology, and proper treatment is essential to protect downstream aquatic ecosystems and water quality in the Balsas River watershed.

The plant discharges into the Balsas River basin, which flows through Guerrero and Michoacán before reaching the Pacific Ocean. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The region's tropical climate and steep topography make it sensitive to erosion and pollution, so effective wastewater treatment is critical to maintaining water quality and ecological health in the river system.
