Welcome to the City of Omaha’s combined sewer overflow (CSO) program
website. This site will help you understand what an overflow is
and steps Omaha is taking to reduce raw sewage from overflowing
into the Missouri River, Papillion Creek. An overflow, called a
CSO, happens during wet weather (rains or snowmelts) when stormwater
enters the sewer system along with sanitary sewage and the capacity
is inadequate. Currently this occurs about 58 times a year in Omaha.
We plan to reduce that number to four times a year.
Omaha is working hard to meet the unfunded Federal mandate to control
CSOs. Solutions to control the overflows have been identified. Refinements
to those solutions are in progress.
Browse around this site to learn more about the CSO!, Clean Solutions
for Omaha program. We've tried to anticipate your questions on the
Frequently Asked Questions (FAQ) page. Numerous maps, photos and
publications will tell you what general areas may be directly affected
by the construction over the next 20 years and what guided the city
to select the solutions proposed. And you'll find newspaper articles,
TV and radio stories as well as individual basin newsletters in
the Newsroom.
If you have specific questions, call our CSO Hotline at 402-341-0235 or email us.
