Benito Juarez Wastewater Treatment Plant, Baja California Sur, Mexico

The Benito Juarez wastewater treatment plant is located in the municipality of Comondú, Baja California Sur, Mexico. It serves a small population of 351 residents, providing secondary treatment for municipal wastewater. The plant is situated inland, away from coastal areas, and operates as part of the local water infrastructure. The plant employs secondary treatment processes, which are standard for small communities in Mexico. With a design capacity of 864.00 m³/day and an actual discharge volume of 259.20 m³/day, the facility operates well below its capacity. Mexican regulations for wastewater treatment are governed by NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is discharged into local water bodies, contributing to the protection of the region's arid ecosystem. Baja California Sur's watersheds are characterized by seasonal streams and limited surface water, making proper wastewater management critical for preserving groundwater quality and supporting local biodiversity.

The plant discharges into the local watershed of Baja California Sur, a region with arid climate and limited surface water. The receiving water body ultimately drains into the Pacific Ocean, supporting coastal ecosystems. Proper treatment helps protect groundwater recharge areas and downstream habitats from nutrient pollution and pathogens.
