An electrical problem at a waste water treatment plant in Bellevue caused untreated sewage to pour into the Missouri River.

The city of Omaha says the problem began about 4 p.m. Friday at the Papillion Creek Wastewater Treatment Plant, just south of Offutt Air Force Base. The electrical problem caused about 115 cubic feet per second of sewage to be discharged into the river.

Workers were able to fix the problem within about four hours.

Before the problem was resolved, Omaha Public Works advised people to stay out of the river south of the confluence with Papillion Creek and several miles downstream. Officials lifted that advisory after the flow or untreated sewage stopped.
