Overview
La Lagunita wastewater treatment plant in Durango, Mexico, serves a small community of 374 people with secondary treatment. It discharges 35.42 cubic meters per day, operating within national water quality standards.
La Lagunita wastewater treatment plant is located in the rural community of El Terrero, within the municipality of Santiago Papasquiaro, Durango, Mexico. The plant serves a small population of 374 residents, reflecting its role in managing domestic wastewater for a compact settlement in the Sierra Madre Occidental region. The facility provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 42.34 cubic meters per day and an actual discharge volume of 35.42 cubic meters per day, the plant operates below its capacity, indicating adequate headroom for current demand. As a Mexican wastewater facility, it falls under the national regulatory framework, including NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is likely discharged into a local stream or arroyo that feeds into the San Lorenzo River basin, ultimately draining into the Pacific Ocean via the Presidio River. The surrounding watershed supports semi-arid ecosystems and agricultural activities, making proper wastewater treatment essential for protecting downstream water quality and community health.
Environmental context
The plant discharges into a local watercourse within the San Lorenzo River basin, which flows through the Sierra Madre Occidental into the Presidio River and eventually reaches the Pacific Ocean. This semi-arid region relies on limited surface water resources for irrigation and domestic use, so the plant's secondary treatment helps reduce organic pollution and protect aquatic habitats in the downstream ecosystem.
