El Carrizo Wastewater Treatment Plant, Ejido la Ventana, Sinaloa

El Carrizo is a wastewater treatment plant located in the Ejido la Ventana (El Carrizo) area of Elota municipality, Sinaloa, Mexico. The plant serves a small population of 548 residents, reflecting its role in a rural or peri-urban setting. As part of Mexico's wastewater infrastructure, it contributes to local sanitation and environmental protection. The plant operates with secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. Its designed capacity is 77.76 cubic meters per day, with an actual discharge volume of 51.84 cubic meters per day, indicating it is operating below capacity. Under Mexico's national water regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater to meet discharge quality criteria. The treated effluent is discharged into the local environment, likely into a nearby river or stream that drains toward the Pacific Ocean. Sinaloa's coastal plain supports agriculture and fisheries, making proper wastewater treatment essential for protecting downstream water quality and aquatic ecosystems. The plant's operation helps reduce pollution loads in the region's water bodies.

The plant's discharge likely enters a local watercourse that flows through the Sinaloa lowlands toward the Pacific Ocean. This region supports diverse aquatic life and is important for local fisheries and agriculture. Proper treatment is critical to prevent nutrient loading and pathogen contamination in downstream waters, which can affect both human use and ecological health.
