LYMAN WWTP - Lyman, Nebraska Wastewater Treatment Plant

LYMAN WWTP is a municipal wastewater treatment facility located in Lyman, Nebraska, a small town in Scotts Bluff County. The plant serves a population of 421 residents, providing essential sanitation services to this rural community in the Great Plains region. The plant employs secondary treatment, which is the standard biological treatment process required by the US Clean Water Act for municipal wastewater. With a designed capacity of 227.12 cubic meters per day and an actual discharge volume of 189.27 cubic meters per day, the facility operates at approximately 83% capacity. As a US plant of this scale, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit issued by the Nebraska Department of Environment and Energy. The treated effluent from LYMAN WWTP is discharged into the local watershed, which ultimately drains into the North Platte River system. The North Platte River flows eastward across Nebraska, joining the Platte River, a critical water source for agriculture and wildlife in the central United States. The plant's secondary treatment ensures that the discharge meets federal and state water quality standards, protecting downstream aquatic habitats and recreational uses.

LYMAN WWTP discharges into the North Platte River basin, a tributary of the Platte River system that flows through Nebraska and eventually joins the Missouri River. The North Platte River supports diverse aquatic life and is an important migratory corridor for birds along the Central Flyway. The plant's secondary treatment helps maintain water quality in this semi-arid region, where water resources are critical for irrigation and ecosystem health.
