Osiris Wastewater Treatment Plant, Colonia Osiris, Zacatecas | Mexico

Osiris is a wastewater treatment plant located in Colonia Osiris, Guadalupe, Zacatecas, Mexico. It serves a population of approximately 46,321 people, placing it in the medium agglomeration category. The plant is part of the municipal wastewater infrastructure for the Guadalupe area. As a Mexican wastewater facility, Osiris operates under the framework of the Ley de Aguas Nacionales and Normas Oficiales Mexicanas (NOMs), which set discharge standards for municipal wastewater. For a plant serving this population size, secondary treatment is typically required to meet environmental regulations. The plant's treatment processes and capacity are managed to comply with these standards. The treated effluent from Osiris is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Río Grande de Santiago system. The plant plays a key role in protecting downstream water bodies, including rivers and reservoirs in Zacatecas, by reducing pollutant loads before discharge.

Osiris discharges into the local drainage network within the Río Grande de Santiago basin, which flows through central Mexico to the Pacific Ocean. The watershed supports diverse aquatic life and is used for agriculture and recreation. Effective treatment at Osiris helps prevent eutrophication and protects water quality in downstream ecosystems, including reservoirs and coastal areas.
