Santa Clara Pueblo Wastewater Treatment Plant, New Mexico

The Santa Clara Pueblo wastewater treatment plant is located in Santa Clara Pueblo, New Mexico, within Rio Arriba County. It serves a small community of 980 residents, reflecting the rural character of the area. The plant is situated near the Rio Grande, which is the primary watercourse in the region. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. It has a designed capacity of 757.08 cubic meters per day and discharges a similar volume. Under the National Pollutant Discharge Elimination System (NPDES), such facilities must obtain permits that set effluent limits to protect water quality. The treated effluent likely discharges into the Rio Grande or a tributary, which flows southward through New Mexico and Texas, eventually reaching the Gulf of Mexico. The Rio Grande supports diverse aquatic life and is a critical water source for agriculture and communities in the arid Southwest. The plant's operations help maintain water quality in this important river system.

The plant discharges into the Rio Grande basin, which drains into the Gulf of Mexico. The Rio Grande is a vital water source in the arid Southwest, supporting riparian habitats, migratory birds, and endangered species such as the Rio Grande silvery minnow. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream ecosystems and water users.
