Fort Sumner STP - Secondary Wastewater Treatment in Fort Sumner, New Mexico

Fort Sumner STP is a municipal wastewater treatment facility located in Fort Sumner, De Baca County, New Mexico. The plant serves a population of approximately 1,390 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 567.81 cubic meters per day and currently treats an average daily flow of 302.83 cubic meters per day. This indicates that the facility operates well within its design capacity, allowing for future growth or seasonal variations. The treatment process is typical for small communities in the arid Southwest, where water conservation and efficient treatment are critical. The treated effluent is discharged to the local watershed, which ultimately drains into the Pecos River. The Pecos River flows through eastern New Mexico and Texas before joining the Rio Grande. The plant's discharge contributes to the river's base flow, supporting aquatic life and downstream water users. Proper treatment helps protect water quality in this semi-arid region where water resources are scarce.

The plant discharges into the Pecos River basin, a major tributary of the Rio Grande. The Pecos River provides critical habitat for fish and wildlife, including the endangered Pecos pupfish. Downstream, the river flows through agricultural areas and eventually joins the Rio Grande near Del Rio, Texas. Maintaining good water quality is essential for irrigation, recreation, and ecosystem health in this water-limited region.
