Hinckley Wastewater Treatment Plant, Utah - Secondary Treatment for Small Community

The Hinckley wastewater treatment plant is located in Hinckley, Millard County, Utah, serving a small population of 693 residents. The facility operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 378.54 megaliters and an annual discharge volume of 302.83 megaliters, the plant operates within its capacity. As a small inland facility, it is not subject to coastal discharge regulations. The treated effluent is discharged into local waterways that drain into the Great Basin, an endorheic basin with no outlet to the ocean. The plant's operations help protect the fragile desert ecosystem and groundwater resources in this arid region of Utah.

The plant discharges into the Great Basin, a closed drainage basin where water flows into terminal lakes or evaporates. This arid region relies on careful water management to sustain local wetlands and wildlife. The treatment plant helps protect the Sevier River system and the Great Salt Lake ecosystem from nutrient pollution and pathogens.
