Overview
Pueblos Unidos wastewater treatment plant serves 5,924 people in Sinaloa, Mexico. It is located near the Pacific coast and discharges into local water bodies.
Pueblos Unidos is a wastewater treatment plant located in the town of the same name within the municipality of Culiacán, Sinaloa, Mexico. It serves a population of approximately 5,924 residents, placing it in the small-to-medium agglomeration category. The plant is situated near the Pacific coast, within 50 km of the ocean, and its operations are subject to Mexican environmental regulations (NOM-001-SEMARNAT). As a small-scale municipal facility, Pueblos Unidos is expected to provide at least secondary treatment under Mexican standards to reduce organic load and suspended solids before discharge. Plants of this size in Mexico typically employ conventional activated sludge or lagoon systems. The population served suggests a moderate flow. The plant's treated effluent likely discharges into local streams or drainage channels that ultimately flow into the Pacific Ocean via the Culiacán River basin. This coastal discharge requires careful management to protect marine ecosystems, including nearby estuaries and coastal lagoons that support diverse aquatic life and fisheries.
Environmental context
The plant is located in the Culiacán River basin, which drains into the Pacific Ocean via the Gulf of California. The region's coastal waters support important fisheries and migratory bird habitats. Discharge from the plant must comply with Mexican standards to prevent nutrient enrichment and pathogen contamination in downstream water bodies, which are ecologically sensitive due to their role in supporting local biodiversity and economic activities like fishing and tourism.
