ACOMA PUEBLO LAGOON Wastewater Treatment Plant, Lake Valley, New Mexico

ACOMA PUEBLO LAGOON is a wastewater treatment plant located in Lake Valley, Sierra County, New Mexico, United States. It serves a small population of 226 residents, reflecting its role in a rural community. The plant is situated near New Mexico State Road 27 in a sparsely populated area. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. Its designed capacity is 113.56 volume units, and the current discharge volume matches this figure. As a small facility, it operates under the regulatory framework of the US Environmental Protection Agency (EPA) and the New Mexico Environment Department, which issue National Pollutant Discharge Elimination System (NPDES) permits to ensure compliance with water quality standards. The treated effluent is discharged into local waterways that ultimately drain into the Rio Grande basin, a critical water source for the arid Southwest. The downstream environment supports diverse aquatic life and provides water for agricultural and municipal use. The plant's location inland, far from the coast, reduces direct marine impact, but its discharge contributes to the overall health of the regional watershed.

The plant discharges into the Rio Grande basin, which flows south through New Mexico and Texas, eventually reaching the Gulf of Mexico. This watershed is ecologically sensitive, supporting species such as the Rio Grande silvery minnow and providing habitat for migratory birds. The arid climate makes water quality and conservation particularly important for downstream communities and ecosystems.
