Las Delicias o Barranca Blanca is a wastewater treatment plant located in Tepic, the capital city of Nayarit state in western Mexico. The plant serves an estimated population of 86,638 people, placing it in the medium-to-large agglomeration category for Mexican wastewater infrastructure. As a plant serving over 50,000 people, it is subject to Mexico's official standards NOM-001-SEMARNAT-1996 and NOM-002-SEMARNAT-1996, which set maximum permissible limits for pollutants in wastewater discharges. These regulations require secondary treatment or equivalent to reduce organic matter and suspended solids. Facilities of this scale typically employ biological treatment systems such as activated sludge or aerated lagoons. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Santiago River basin. The region's tropical climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and coastal water quality. The plant plays a key role in maintaining public health and environmental standards in the Tepic metropolitan area.
