LOS ALAMOS STP - Wastewater Treatment Plant in Los Alamos, New Mexico

LOS ALAMOS STP is a municipal wastewater treatment facility located in Los Alamos, New Mexico, serving a population of about 19,600. Situated in the high desert of the southwestern United States, the plant manages wastewater from the community and nearby areas. As a US facility, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the New Mexico Environment Department. For a population of this size, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The treated effluent is discharged into the local watershed, which ultimately drains into the Rio Grande, a major river system that flows through New Mexico and Texas before reaching the Gulf of Mexico. The plant plays a key role in protecting water quality in this arid region, where water resources are critical for both ecological health and human use.

The plant discharges into the Rio Grande basin, a vital water source in the arid Southwest. The Rio Grande supports diverse aquatic life and provides irrigation and drinking water for millions. Downstream, the river flows through the Rio Grande Valley and into the Gulf of Mexico, making the plant's treatment performance important for both local ecosystems and downstream water quality.
