El Rodeo Wastewater Treatment Plant, San Juan del Río, Querétaro

El Rodeo is a wastewater treatment plant located in San Juan del Río, Querétaro, Mexico. It serves a small population of 1,369 people, reflecting its role in a smaller community within the region. The plant operates with secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 259.20 cubic meters per day and a current discharge volume of 129.60 cubic meters per day, the plant operates at roughly half its capacity. As a Mexican facility, it falls under national water quality regulations, including NOM-001-SEMARNAT-1996, which sets limits for pollutants in wastewater discharges. For a plant of this scale, secondary treatment is typical and meets the required standards for protecting water resources. The treated effluent is likely discharged into a local watercourse that eventually drains into the San Juan River, a tributary of the Pánuco River system. This river system flows into the Gulf of Mexico, making the plant's performance important for downstream aquatic ecosystems and coastal water quality.

The plant's discharge enters the San Juan River watershed, which flows into the Pánuco River and ultimately reaches the Gulf of Mexico. This region supports diverse aquatic life and is ecologically sensitive due to its role in maintaining water quality for downstream communities and habitats. Proper treatment helps prevent nutrient loading and contamination that could affect the river's health and the Gulf's coastal ecosystems.
