Theresa Street STP - Lincoln, Nebraska Wastewater Treatment Plant

Theresa Street STP is a major wastewater treatment facility located in Lincoln, Nebraska, serving a population of around 198,000. As a large municipal plant, it plays a critical role in managing the city's wastewater and protecting public health. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater. Plants of this scale typically employ advanced secondary or tertiary treatment to meet NPDES permit limits. The treated effluent is discharged into the Salt Creek watershed, which flows into the Platte River and eventually the Missouri River. This drainage system supports diverse aquatic life and provides water for agricultural and recreational uses downstream.

The plant discharges into Salt Creek, a tributary of the Platte River, which flows into the Missouri River and ultimately the Mississippi River system. The Platte River is a critical migratory corridor for sandhill cranes and other waterfowl, and supports diverse fish populations. The watershed is ecologically sensitive, with nutrient management being a key concern to prevent downstream eutrophication.
