Sewer Collection System Model
In 2003, the City embarked on creating a computer model of its sewer collection system. The primary purpose was to support development of the (2009) CSO Long Term Control Plan (LTCP), by characterizing sewer system components, improving understanding of system operations, and identifying cost effective controls. The model was used to develop the original LTCP in 2009 and for LTCP updates in 2014 and 2021. The model informs CSO project designs by identifying concerns and constraints. As the model evolves, changes to the sewer system are continually incorporated. This allows the team to identify cost-effective controls and answer complex questions.

Adams Park: Construction Time Lapse
This video illustrates construction at the John Creighton Boulevard & Miami / Adams Park Project from September 2014 to June 2016.
Background on the SEB Program
One goal for the CSO Program was to encourage contracting with small and emerging small businesses (SEBs), outreach to youth and to provide opportunities to build a strong workforce.
Beaver Dam
Omaha uses other green infrastructure to reduce stress on its storm sewers, including a structure resembling a beaver dam, which collects water during heavy rain events.

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.

Getting SEBs Involved
CSO reaches out to small and emerging small businesses (SEBs) and contractors through informational events before bids go out and connects them to resources designed to help them bid better in order to grow their businesses.
Green Infrastructure
This two-minute animation, suggested for kids 10 and older, explains what green infrastructure is, where it can be seen in our community, and how it contributes to the CSO Program's goal of reducing bacteria in our rivers and streams.
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.
How the REACH Program Works
CSO does outreach events with the REACH program through the Chamber of Commerce, which aligns projects with work opportunities in the community.
Infraestructura verde
Esta animación de dos minutos, sugerida para niños mayores de 10 años, explica qué es la infraestructura verde, dónde se puede ver en nuestra comunidad y cómo contribuye a la OSC. El objetivo del programa es reducir las bacterias en nuestros ríos y arroyos.
Jim Theiler, Assistant Public Works Director, Environmental Services Talks About the CSO Program
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.

Spring Lake Park
Spring Lake Park, an area once blighted with pollution, became a clean, usable space that matches stormwater retention with public value.
Spring Lake Park: Bringing the Plan to CSO
By creating a dialogue with the neighborhood, the CSO project was designed to suit both the ecological needs of a stormwater retention pond as well as the needs of the community to restore an amenity.

Spring Lake Park: Green Infrastructure
CSO has become a best practice for forward-thinking national change by researching and implementing green infrastructure as part of the community’s solution for improving water quality.
Spring Lake Park: Implementing the Plan
CSO worked with the University of Nebraska - Lincoln’s water resource center to plan solutions for how to keep water clean and design the space.
Spring Lake Park: Inspiring Other Cities
This project serves as a strong example for Omaha and beyond of how cities and people can work together to inspire change in their communities.

Thanks to strong neighborhood involvement before the fact, the timing was perfect for CSO and the community to come together on this project.
Spring Lake Park: The Finished Project
After a picturesque reveal at the project’s news conference with the mayor, the diversity of plants and wildlife present added to the project’s success to create a clean, properly functioning green solution in the park.
Using Local Contractors
Besides the emphasis on working with small businesses, CSO has awarded 80% of contracts to local contractors, which strengthens Omaha’s local economy.
