The Missouri River Water Resource Recovery Facility (MRWRRF) was built in 1964. Before improvements were completed, the MRWRRF could treat approximately 50 million gallons of wastewater per day during wet weather events. Upgrades now allow the MRWRRF to treat 150 million gallons per day during wet weather flows, ultimately reducing the amount of untreated wastewater sent to the Missouri River. The MRWRRF CSO improvement were completed in three major phases or schedules (A, B1, B2). In addition, a separate project to replace the pumps to ensure reliability is currently under construction.
These improvements, when combined with other projects that are being built to deliver additional wet weather flows to the MRWRRF, will result in a significant reduction in bacterial loading to the Missouri River, consistent with the goals of the Long Term Control Plan.
*As of August 2017, the Missouri River Wastewater Treatment Plant (MRWWTP) Improvements Project is now known as the Missouri River Water Resource Recovery Facility (MRWRRF) Improvements Project.
The second wastewater pump was installed in March 2021. Testing of this pump and the first stormwater pump occurred in April 2021.
