Villa Ignacio Zaragoza Wastewater Treatment Plant, Baja California Sur, Mexico

Villa Ignacio Zaragoza is a municipal wastewater treatment plant located in Villa Ignacio Zaragoza, within the municipality of Comondú, Baja California Sur, Mexico. The plant serves a small population of 548 residents, reflecting its role in a rural or small community setting. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 432.00 cubic meters per day and an actual discharge volume of 86.40 cubic meters per day, the plant operates well below its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges into national waters, ensuring compliance with federal water quality standards. The treated effluent is discharged into the local environment, contributing to the protection of groundwater and surface water resources in the Baja California Sur region. The plant's inland location, over 50 km from the coast, means its discharge does not directly impact marine ecosystems but supports the arid region's water quality and public health.

The plant is situated in the arid Baja California Sur region, where water resources are scarce and sensitive. The treated wastewater likely infiltrates into local aquifers or flows into ephemeral streams that drain into the Gulf of California. This inland discharge supports groundwater recharge and prevents contamination of downstream water bodies, which are critical for local agriculture and wildlife. The region's ecosystems, including desert oases and coastal lagoons, depend on maintaining water quality.
