INMAN WWTP - Secondary Wastewater Treatment in Holt County, Nebraska

INMAN WWTP is a municipal wastewater treatment facility located in Holt County, Nebraska, in the United States. It serves a small population of 150 residents, reflecting the rural character of the area. The plant operates under secondary treatment standards, which is the baseline requirement for domestic wastewater in the United States under the Clean Water Act. As a secondary treatment plant, INMAN WWTP uses biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 75.71 cubic meters per day, matching its current discharge volume. Secondary treatment typically involves aeration and settling stages to achieve effluent quality suitable for discharge. The treated effluent is discharged into local waterways, contributing to the health of the surrounding watershed. The plant's location in rural Nebraska means its discharge supports local streams and groundwater recharge, ultimately flowing into the Missouri River basin. Proper treatment helps protect aquatic life and downstream water quality in this agricultural region.

The plant discharges into local water bodies within the Elkhorn River watershed, which flows into the Platte River and eventually the Missouri River. This region supports diverse aquatic habitats and is important for migratory birds. Effective secondary treatment helps maintain water quality in these sensitive prairie streams.
