OMAHA, Neb. (AP) — Omaha’s sewage treatment plant is back online after severe flooding forced public works officials to shut it down and pump raw sewage into the Missouri River for a month. The Omaha World-Herald reports that the city’s Papillion Creek Wastewater Treatment Plant was knocked offline March 15, when statewide flooding forced evacuations and led to hundreds of millions of dollars in damages. The plant resumed full treatment last week.

Plant manager Dave Sykora says he thought it would take much longer to restore the plant. The flooding caused $35 million in damages at the plant and forced the Omaha Public Works Department to send raw sewage to the Missouri River for 33 days. The longest time the plant had previously released sewage into the river was for three days in 2017.
