The purpose of the Saddle Creek Retention Treatment Basin (SCRTB) Project is to capture combined sewage and store or treat it during wet weather events. Combined sewage will be diverted from the Saddle Creek Sewer and conveyed to the SCRTB headworks, where large materials like cans, rocks, tree branches and floatable solids are removed using a grit pit and mechanical screens. Directly following screening, a disinfectant will be added to the combined sewage flows to kill or inactivate pathogenic bacteria. For small wet weather events, the combined sewage will be fully captured (retained) in the underground basin. For larger events, the underground basin will completely fill up and then a dechlorination agent will be added just prior to flows discharging through an overflow channel to the Little Papillion Creek. Once completed, the RTB will capture and treat a combined sewage flow rate of up to 160 million gallons per day. The headworks and chemical storage and feed systems were designed to accommodate peak instantaneous flow rates up to 320 million gallons per day to allow for large flow variations into the basin and also the potential for treating higher flows in the future. The RTB will use dewatering pumps to empty the facility after a wet weather event has ended. These pumps will convey captured combined sewage volume into the downstream Papillion Creek Interceptor sewer for treatment at the Papillion Creek Water Resource Recovery Facility (PCWRRF)
Construction is currently ~93% complete with final completion expected in Summer of 2023. Stephen D'Alecy, project construction manager with Wade Trim, will be leading the presentation. City of Omaha project engineers Jake Hansen and Michael Zelensky will also be in attendance to answer questions.
