CSO Perspectives: Managing Risk — All Projects Have Risk
All projects have elements of risk. As the City works to deliver the many projects that make up the CSO Program, managing risk is critical to success. The CSO Program proactively manages risk on a project-by-project basis by identifying, understanding, and mitigating risks that could impact budget and schedules.

CSO Facilities

This video explains the steps of combined sewage treatment at the Missouri River Water Resource Recovery Facility and how other area facilities work to improve the water quality of our river and streams.

CSO Projects Funded by NET, Part 1

Despite being a mandated program, CSO projects explored numerous methods to create rain gardens, bioswales and other solutions to improve how wastewater is handled.

CSO Projects Funded by NET, Part 2

By implementing various ecological solutions, Omaha can keep stormwater in more natural ecosystems rather than forcing it into wastewater treatment plants.

Engaging EEIP

CSO works to encourage small businesses, to create opportunities within CSO projects and to educate youth through its Economic Inclusion Plan.

How Much Has Already Been Done

Accounting for all completed projects, as well as projects actively underway, it is estimated that, when completed, the Program will capture 80% of combined sewage overflow to the Missouri River watershed.

How Omaha Pays

Projects are financed through the sale of 30-year bonds, as needed. The bonds are repaid through sewer usage fees from residents, businesses and wholesale users.

Omaha Compared to Other Cities

Omaha is one of the largest cities with a combined sewer system, producing eight billion gallons a year of combined sewage that must be processed at a program cost of $2 billion.

Outreach: World O' Water

By promoting education about stormwater and its impact on communities, people can better understand the need for green infrastructure and why they are worth the investment long-term.

Overview of CSO

Omaha’s older sewer system east of 72nd street combines wastewater from homes with rain from weather events, meaning that in overflow, sewage leads to Omaha’s watersheds, causing pollution.

Program Overview

Clean Solutions for Omaha works to make our rivers and streams cleaner and safer for everyone in Omaha. Check out this video to learn more about our goals and the impact of our projects in the community.

Working with Regulators

Omaha maintains a positive relationship with regulators which allows the city to have some flexibility to manage changes in the project.
