    Project Spotlight

    Improvements continue at the Missouri River Wastewater Resource Facility. When combined with other projects being built to deliver additional wet weather flows to the plant, improvements will result in a significant reduction in bacterial loading to the Missouri River and help meet Program goals.

    In July, the City celebrated the opening of the Spring Lake Park Pond and the completion of the Phase 1 Sewer Separation Project. Construction of Phase II of the sewer separation project will begin this fall and includes separation and improvements south of F Street and through the golf course.

    Community Acceptance

    CSO Program staff attended the annual World 'O Water event in September, which is a fun, annual event for people of all ages to learn about the important role that water plays in our lives and community.

    Current Construction

    Construction work continues on the South Interceptor Force Main North Segment. The new tunnel boring machine completed excavation on Aug. 15, and has been removed from the tunnel shaft; the old tunnel boring machine was also removed after encountering a geologic anomaly in 2016. Substantial completion for the project is expected in the fourth quarter.

    Public Involvement

    A public meeting was held for the Lake James to Fontenelle Park Lagoon and Sewer Separation Project to provide an update on the current lagoon construction and the schedule for both the lagoon and sewer separation construction


The CSO Program is designed to improve the water quality in our local rivers and streams.

Today, approximately 52 times each year, raw sewage mixed with stormwater flows into the Missouri River and the Papillion Creek. Through the CSO Program, we will reduce that number.

CSO Program Partners with Omaha Chamber, Engages SEB Community

The CSO Program values the inclusion of the Small and Emerging Small Business Program (SEBs) in the construction of the Program’s projects. Partnering with Omaha Chamber REACH Program, whose mission is to help SEBs build capacity, outreach meetings are planned in coordination with current construction bid opportunities. The Lake James to Fontenelle, Paxton Basin Upstream Sewer Separation construction project was advertised for construction bid earlier this month, and a REACH plan room meeting held on Nov. 16. This meeting took place at REACH’s Metropolitan Community College campus plan room, which provided a one-on-one opportunity for SEBs to meet and talk with both the project design team as well as general contractors. These REACH plan room events will be held in conjunction with all the construction bid opportunities in the future. The City values SEB inclusion, and CSO’s partnership with REACH provides an additional way to further educate and engage the SEB community.

NDEQ, NDHHS Tour Omaha CSO Projects

The City of Omaha staff, with assistance from Program Management Team, provided an overview of the CSO Program to approximately 19 individuals with the Nebraska Department of Environmental Quality (NDEQ) and the Nebraska Department of Health and Human Services (NDHHS). While the NDEQ has been involved in the CSO Program for many years, they have recently begun sharing staff with NDHHS for efficiency. The purpose of the overview and tour was to educate staff members of both agencies, many of whom are new, about the efforts the City is taking to address combined sewer overflows. The NDEQ is anticipating a significant number of retirements in the near future, and requested the overview to begin educating replacement staff.

The overview included a presentation on the history of the Omaha collection system, the status of implementation of the CSO Long Term Control Plan, its positive impact on water quality, and an overview of the work being done at the Missouri River Water Resource Recovery Facility. A tour of some of the CSO projects followed the information sessions. These projects included the MRWRRF Improvements, Leavenworth Lift Station, South Interceptor Force Main, Gilmore Avenue Sewer Separation, Adams Park, Fontenelle Park Lagoon, and the South Omaha Industrial Area (SOIA) Lift Station. Positive feedback was received from participating departments.

Value Engineering to Implement Cost-Effective Solutions

The CSO Program continues its fiscal vigilance by looking for multiple ways to reduce the impact on ratepayers. The City’s effort on the Environmental Protection Agency’s Water Infrastructure Finance and Innovation Act (WIFIA) application continues. The WIFIA Program provides low interest loans for eligible projects, and the City’s Saddle Creek Retention
Treatment Basin project was recently selected as one of 12 nationally funded projects for a loan amount of up to $55 million. This loan will provide significant cost savings for the City on this project due to the lower interest rate, and the delayed repayment term. The current plan is to submit the WIFIA Application by the end of the year with plans and specifications to be submitted at a later date.

CSO Program Staff Attends World 'O Water to Promote Learning

CSO Program staff recently attended the World 'O Water event. This is an annual event for families at Chalco Hills to learn about stormwater, wastewater, clean air and other environmental issues. The CSO Program developed a Wheel of Water game where kids were asked questions like "How can you keep water from going into the sewer when you brush your teeth?" If answered correctly, they were given a reusable water bottle and a kid friendly handout about things they could do to help.

Missouri River Wastewater Treatment Improvements

Missouri River Wastewater Treatment Plant (MRWWTP) Improvements Project was identified as an early action project in the Combined Sewer Overflow (CSO) Long Term Control Plan. Improvements are needed to treat a higher flow rate of combined sewage during wet weather events and provide separate treatment of industrial wastewater to keep contaminants out of the Missouri River. Improvements will allow the MRWWTP to accept and treat up to 150 million gallons per day. This is accomplished through a combination of new facilities and maximizing the use of existing facilities.

Although the MRWWTP Improvements Project is designed to treat wastewater, other CSO projects are needed to deliver wastewater to the plant for treatment. It is estimated that treatment and conveyance projects working together will reduce E. coli loading to the River by approximately 50%. The $140M expended at the MRWWTP provides a substantial return on investment in terms of E. coli reduction. (Read more.)
