Abiquiu Lagoon Wastewater Treatment Plant, Abiquiu, New Mexico

Abiquiu Lagoon is a municipal wastewater treatment facility located in Abiquiu, New Mexico, within Rio Arriba County. The plant serves a small population of 169 residents, providing secondary treatment to manage domestic wastewater from the community. As a secondary treatment plant, Abiquiu Lagoon meets the standard requirements under the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater to reduce organic pollutants and suspended solids. The plant's designed capacity is 75.71 volume units, with a similar discharge volume, indicating it operates at full capacity for its small service area. The treated effluent from Abiquiu Lagoon is discharged into the local environment, contributing to the Rio Chama watershed, which flows into the Rio Grande. This river system supports diverse aquatic life and provides water for irrigation and recreation downstream. The plant's location inland, far from the coast, reduces direct marine impact.

The plant discharges into the Rio Chama basin, a tributary of the Rio Grande, which ultimately flows into the Gulf of Mexico. The Rio Chama supports a variety of fish species and provides critical habitat for migratory birds. The arid climate of New Mexico makes water quality management essential for maintaining the ecological health of this river system.
