Exhacienda Delicias Wastewater Treatment Plant, Rosales, Chihuahua

Exhacienda Delicias wastewater treatment plant is located in the Rosales municipality of Chihuahua, Mexico, serving a population of 1,369. The plant provides secondary treatment, a standard level for small communities in Mexico, and has a designed capacity of 172.80 m³/day with an average discharge volume of 129.60 m³/day. As a secondary treatment facility, Exhacienda Delicias meets the basic requirements for organic matter and suspended solids removal. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. Plants serving small populations like this one are typically subject to less stringent monitoring than larger urban facilities. The treated effluent is discharged into local watercourses that drain into the Rio Conchos basin, a tributary of the Rio Grande (Rio Bravo). The Rio Conchos is an important water source for agriculture and ecosystems in the Chihuahuan Desert. Proper treatment helps protect downstream water quality and supports the region's water sustainability.

The plant discharges into the Rio Conchos basin, which flows into the Rio Grande (Rio Bravo) and ultimately reaches the Gulf of Mexico. The Chihuahuan Desert ecosystem relies on these water bodies for habitat and agricultural irrigation. Effective secondary treatment reduces organic pollution and helps maintain water quality in this arid region, where water resources are scarce and ecologically sensitive.
