Mescalero Lagoon Wastewater Treatment Plant, Mescalero, New Mexico

Mescalero Lagoon is a wastewater treatment facility located in Mescalero, New Mexico, serving a population of approximately 2,371 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring effective removal of organic matter and suspended solids. The plant has a designed capacity of 454.25 units and a discharge volume matching that figure, indicating full utilization. As a US facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the New Mexico Environment Department or the US EPA, governing effluent limits and monitoring requirements. The treated effluent is discharged into the local watershed, which ultimately drains into the Rio Grande basin. This region supports diverse aquatic life and is important for water supply in the arid Southwest. The plant's inland location reduces direct marine impact, but its discharge contributes to the health of downstream ecosystems.

The plant discharges into the local watershed within the Rio Grande basin, a major river system that flows through New Mexico and Texas before reaching the Gulf of Mexico. The receiving waters support sensitive aquatic habitats and are crucial for regional water resources. The arid climate means that effluent quality is vital for maintaining streamflow and ecological balance in downstream environments.
