The San Francisco wastewater treatment plant is located in San Francisco (San Pancho), a coastal town in the municipality of Bahía de Banderas, Nayarit, Mexico. The facility serves a population of approximately 4,268 residents and is situated within 10 km of the Pacific Ocean, making it a coastal plant with potential marine discharge implications. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater before discharge into coastal waters. The designed capacity is 1,036.80 m³/day, with an actual discharge volume of 864.00 m³/day, indicating a utilization rate of about 83%. As a small agglomeration, the plant is subject to national water quality standards that set limits on biochemical oxygen demand, total suspended solids, and other parameters. The treated effluent likely discharges into the Pacific Ocean via a nearby stream or directly through an outfall, affecting the coastal waters of Bahía de Banderas. This bay supports diverse marine life, including sea turtles and migratory fish, and is an important ecological and tourism area. The plant's performance is critical to maintaining water quality in this sensitive coastal environment.
Environmental context
The plant discharges into the Pacific Ocean via the coastal waters of Bahía de Banderas, which ultimately drains into the open Pacific. This bay is an ecologically sensitive area that supports coral reefs, mangroves, and seagrass beds, providing habitat for numerous marine species. The region's tropical climate and tourism-driven development make proper wastewater treatment essential to prevent nutrient pollution and protect coastal ecosystems.
