The Saddle Creek RTB: A Storage and Treatment Solution for CSO

The City of Omaha Public Works Department is undertaking a major water quality improvement program called Clean Solutions for Omaha, or CSO! which will improve water quality in Omaha’s rivers and streams by capturing or treating 85% of the average annual combined sewage volume through a series of projects. One of the major projects as part of this program is the Saddle Creek Retention Treatment Basin. 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. This paper describes how wet weather storage and treatment technology was applied to attenuate excessive flows for the purposes of meeting the Long-Term Control Plan requirements for control of combined sewer overflows.
