TROPIC Wastewater Treatment Plant, Tropic, Utah | Secondary Treatment Facility

TROPIC wastewater treatment plant is located in Tropic, Garfield County, Utah, United States. It serves a small population of 530 residents, providing essential wastewater management for this rural community. The plant operates under the regulatory framework of the US Clean Water Act, which mandates secondary treatment as the minimum standard for municipal wastewater facilities. The plant has a designed capacity of 870.64 cubic meters per day and currently treats a discharge volume of 234.70 cubic meters per day. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. This level of treatment is appropriate for the small population served and helps protect downstream water quality. The treated effluent is discharged into local water bodies that drain into the Colorado River Basin, a critical water resource for the arid southwestern United States. The plant's operations contribute to maintaining the ecological health of the region's streams and rivers, which support diverse aquatic life and provide water for agriculture and recreation.

The plant discharges into local streams that are part of the Colorado River Basin, ultimately flowing into the Colorado River and then to the Gulf of California. This watershed is ecologically sensitive, supporting species such as the Colorado pikeminnow and razorback sucker. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this arid region.
