Hartville WWTP - Secondary Treatment Plant in Hartville, Wyoming

Hartville WWTP is a municipal wastewater treatment facility located in Hartville, Platte County, Wyoming. The plant serves a small population of 62 residents, reflecting the rural character of the community. It operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required for most municipal facilities in the U.S. to reduce organic matter and suspended solids. The designed capacity is 45.42 megaliters per year, with an actual discharge volume of 22.71 megaliters per year, indicating operational headroom. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a tributary of the North Platte River, which flows through the region. The North Platte River eventually joins the Platte River in Nebraska, contributing to the Missouri River watershed. This system supports diverse aquatic life and provides water for irrigation and recreation downstream.

The plant discharges into a local stream that drains into the North Platte River, a major tributary of the Platte River system. The North Platte River flows through semi-arid terrain in Wyoming and Nebraska, supporting riparian habitats and migratory birds. Downstream, the Platte River is a critical stopover for sandhill cranes and other waterfowl along the Central Flyway. The plant's secondary treatment helps protect water quality in this ecologically sensitive river system.
