GRENOLA WWTP - Secondary Treatment Plant in Grenola, Kansas

GRENOLA WWTP is a municipal wastewater treatment plant located on North Hickory Street in Grenola, Elk County, Kansas. It serves a small population of 234 residents, reflecting the rural character of the community. The facility is part of the local infrastructure managed by the city. The plant provides secondary treatment, a standard biological process that reduces organic matter and suspended solids. With a designed capacity of 94.64 cubic meters per day and a current discharge volume of 75.71 cubic meters per day, the plant operates below its capacity. Under the U.S. Clean Water Act, such facilities must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Kansas Department of Health and Environment, which set effluent limits to protect water quality. The treated effluent is discharged into a nearby unnamed water body that flows into the Elk River, a tributary of the Verdigris River, which ultimately drains into the Arkansas River and then the Mississippi River. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream. The plant's operation helps maintain the ecological balance of the local streams and rivers.
