Rancho Nuevo Wastewater Treatment Plant, Chihuahua, Mexico

Rancho Nuevo is a municipal wastewater treatment plant located in the small community of Rancho Nuevo, within the municipality of San Francisco de Conchos, Chihuahua, Mexico. The plant serves a population of 456 and provides secondary treatment, which is appropriate for a small agglomeration in an inland setting. With a designed capacity of 103.68 volume units and a daily discharge volume of 43.20, the plant operates under Mexico's federal water law (Ley de Aguas Nacionales) and is subject to NOM-001-SEMARNAT-1996 standards for wastewater discharge. Secondary treatment ensures removal of organic matter and suspended solids, meeting regulatory requirements for inland discharge. The plant's treated effluent likely discharges into a local arroyo or tributary that flows into the Conchos River, a major tributary of the Rio Grande (Rio Bravo). The Conchos River supports diverse aquatic life and is an important water source for agriculture and communities in the region. Downstream, the Rio Grande flows to the Gulf of Mexico, making the plant's treatment performance relevant to both local and transboundary water quality.

The plant discharges into the Conchos River basin, which drains into the Rio Grande and ultimately the Gulf of Mexico. The Conchos River is a vital water source for Chihuahua's agricultural and urban areas, supporting species such as the Rio Grande silvery minnow and various migratory birds. Proper secondary treatment helps protect downstream ecosystems and water quality in this semi-arid region.
