Francisco Zarco Wastewater Treatment Plant, Valle de Guadalupe, Baja California

Francisco Zarco is a wastewater treatment plant located in the Valle de Guadalupe region of Baja California, Mexico. It serves the small community of Francisco Zarco, with a population of 1,734, and operates under Mexico's national water regulations. The plant is situated inland, approximately 50 km from the Pacific coast, and plays a role in managing local wastewater in a region known for its wine production and tourism. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 1,296 cubic meters per day and a current discharge volume of 164.16 cubic meters per day, the plant operates well below its capacity. For small communities in Mexico, secondary treatment is typical, and plants are regulated by the National Water Commission (CONAGUA) to ensure compliance with water quality standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Todos Santos Bay area. The Valle de Guadalupe is an ecologically sensitive region, supporting agricultural activities and diverse aquatic life. Proper wastewater treatment is essential to protect downstream water quality and the coastal environment.

The plant discharges into the local watershed that flows toward the Pacific Ocean, specifically into the Todos Santos Bay area. This coastal region supports diverse marine life and is important for local fisheries and tourism. The Valle de Guadalupe is a semi-arid area where water resources are critical for agriculture, including vineyards, making effective wastewater treatment vital for protecting both surface water and groundwater quality.
