Improving Water Quality in Omaha’s Rivers and Streams

KAI provided construction management services for improvements to the Missouri River Wastewater Treatment Plant (WWTP), including construction of new headworks/preliminary screening, flow sampling and measurement, primary and secondary treatment and disinfection, through chlorination and dechlorination.

Capacity at the plant was 35 MGD (million gallons per day). Improvements included increasing capacity to 150 MGD to help meet Omaha’s projected future demand growth and provide immediate protection against wet weather overflows.

Further benefits included in the Schedule B project were reduction of odor from the existing plant and reduction of bacterial and pathogenic concentrations in the outflow to the Missouri River. Biosolids from plant processes were used to produce energy at the Missouri River Wastewater Treatment Plant (WWTP).

KAI’s construction management role included monitoring and evaluating work for quality and conformance to plans and specifications, field coordination of construction activity with plant operations, evaluation of schedule progress, and coordination with the design team to assure that design intent was communicated to the field operation.

The project for the Missouri River Wastewater Treatment Plant (WWTP) was a component phase of Omaha’s CSO (Clean Solutions for Omaha) long-term improvements plan, which has an overall cost of $1.7 billion and expected to be completed in 2027.
