We are improving water quality in our rivers and streams. To do this, we need to reduce the occurrence of combined sewer overflows to Papillion Creek and the Missouri River.
A combined sewer overflow (CSO) is a discharge of raw sewage mixed with stormwater into local waterways during wet weather events like a rainstorm. Overflows occur when there is too much flow for the combined sewer system to handle. To relieve pressure in the system and minimize backups into homes and businesses, excess sewage sometimes flows into local waterways.
Omaha’s combined sewer system dates back to the 1800s and was designed to move wastewater and stormwater out of urbanized areas to the Missouri River which dispersed and carried pollution away.
Though many projects have been initiated to separate parts of the existing combined sewers, most of the combined sewer system is still in use in the older parts of Omaha (east of 72nd Street).
In order to accomplish the goals of Clean Solutions for Omaha, the City of Omaha has developed a Long Term Control Plan (LTCP) that addresses a plan of action, timeline and anticipated costs to meet the mandate.
