Palos Verdes Wastewater Treatment Plant, Sinaloa, Mexico

Palos Verdes is a municipal wastewater treatment plant located in the community of Palos Verdes, within the municipality of Guasave, Sinaloa, Mexico. The plant serves a population of 2,008 people, reflecting its role in managing domestic wastewater for a small agglomeration in this coastal region of northwestern Mexico. The facility provides secondary treatment, which is the standard biological treatment level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharges to water bodies. With a designed capacity of 207.36 cubic meters per day and an actual discharge volume of 190.08 cubic meters per day, the plant operates at a high utilization rate, indicating consistent demand for its services. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Gulf of California. The region's semi-arid climate and agricultural activities make proper wastewater management critical for protecting downstream water quality and supporting local ecosystems.

The plant discharges into the Sinaloa river basin, which flows into the Gulf of California, a biologically rich marine environment. The Gulf supports diverse aquatic life, including commercially important fish species and migratory birds. Effective secondary treatment helps reduce nutrient and pathogen loads, safeguarding water quality in this ecologically sensitive coastal zone.
