ON THE COVER: (Clockwise) Vinton Street Green Infrastructure, Adams Park Wetlands Improvement Project, Nicholas Street Phase 2 to 23rd and Grace, Spring Lake Park Landscaping and Leavenworth Lift Station.
• Saddle Creek Retention Treatment Basin (RTB) Early Soils Removal Project
neared completion. The purpose of this project is to prepare the site for
the Combined Sewer Overflow (CSO) control facility to be constructed in
the future for CSO 205 for the Saddle Creek Basin.
• Coordination efforts commenced for start-up activities for Leavenworth
Lift Station, Missouri River Wastewater Treatment Plant (MRWWTP)
Projects and South Interceptor Force Main (SIFM) North and South/Central
Segment Projects.
• Extensive efforts were completed to communicate with the contracting
community on the MRWWTP B2 Project, which resulted in a favorable
construction bid.
• Spring-fed water and rainfall runoff began to fill the lagoon at Spring Lake
Park, as originally designed.
• Construction issues were addressed and contractor continued work on
the MRWWTP Bank Stabilization.
• Gilmore Avenue Landscape Improvement Project construction was put

ii Omaha Combined Sewer Overflow Control Program | Implementation Phase
CSO
Solutions
Goal 1:
Regulatory
Compliance.Meet specific regulatory requirements as identified by the EPA and NDEQ.
• Complete
implementation of
CSO solutions within
schedule identified.
• Reduce pollutant
discharge to the Missouri River
and Papillion Creek.
Goal 2:
Economic Affordability.Minimize cost impact to ratepayers by completing CSO control options within or under budget.
Goal 3:
Community Acceptance. Maintain continuous public dialogue, provide information and pursue opportunities for multiple benefits in CSO solutions.
The Program schedule, which began in 2006, is shown below. The final implementation is targeted for 2027. The Program is divided into two groups: major projects and sewer separation projects. Project implementation was selected based on its positive effect on water quality, supporting development, its priority in the construction sequence, and cost. The schedules were further coordinated to allow for concurrent construction. A list of projects by LTCP phase is located in the Appendix.
PROGRAMOVERVIEWIn order to comply with the
requirements of the Clean Water
Act, the United States Environmental
Protection Agency (EPA) Combined
Sewer Overflow (CSO) Control Policy
of 1994 and Administrative Consent
Order with the Nebraska Department
of Environmental Quality (NDEQ),
the City of Omaha developed a
Long Term Control Plan (LTCP)
that outlines the actions to control
overflows from its combined sewer
system. The purpose of the Omaha
CSO Control Program (Program)
Implementation Phase is to ensure
that CSO projects outlined in the City
of Omaha’s LTCP are cost effectively
designed, constructed, and placed
into operation by 2027.
CURRENT CSO PERMIT IS VALID THROUGH
OCTOBER 2020The CSO permit was approved by NDEQ in September 2015 with refined requirements that lower the City’s costs and in support of Omaha’s Program. The next required CSO permit renewal is October 2020.

Projects on Hold
Both the Saddle Creek
Retention Treatment Basin
(RTB) and the Minne Lusa
Stormwater Conveyance
System Projects were put
on hold this quarter due
to significantly increased
costs. These are under
evaluation to find more
cost-effective approaches
and additional information on potential
alternatives will be provided at a later date.

LEGISLATIVE ACTION IN SUPPORT OF THE PROGRAMThe City of Omaha is working with the Nebraska Department
of Natural Resources (NDNR) Grant Award Contract to finance
the construction of CSO projects and the water quality
improvements. Under this action NDNR will provide $2.9 million
in 2016 and approximately $1 million per year from 2017 through
2027. This agreement with NDNR for grant funds appeared
on the City Council agenda in June and July 2016 for the
Council’s approval.
Value Engineering (VE) efforts continue on the Saddle Creek RTB project to assess potential cost savings to the Combined Sewer Overflow (CSO) Program as well as providing benefit to the surrounding community. The outcome and recommendations from this VE effort is expected early fall 2016.
VALUE ENGINEERING TO
IMPLEMENT COST-EFFECTIVE
SOLUTIONS
Economic Affordability is the minimization of the cost impact to the ratepayers.
Construction costs have been contained as shown in the following metrics.
Goal 2: Economic Affordability
CURRENT & COMPLETED PROJECTCONSTRUCTION COSTS
RATEPAYER ASSISTANCEWhen the long term control plan (LTCP) was approved it marked the start of a ratepayer assistance plan to help low income and fixed income households with the rate increases necessary to fund the Program.
From April 2016 through June 2016, over $94,443 has been provided in assistance; to date $4.5 million has
been provided. Ratepayers are eligible if they receive Low Income Heat and Energy Assistance (LIHEAP) from their utility. This has kept administrative costs to a minimum and provided the maximum benefit to those who need it.
For assistance or to apply for Nebraska LIHEAP, call 800-383-4278.
PROGRAM OVERVIEW: GOAL 2
4 Omaha Combined Sewer Overflow Control Program | Implementation Phase
Community Acceptance provides continuous open dialogue with the public along
with timely and accurate project information. The Program is also providing additional
neighborhood benefits, beyond the improved sewer system and water quality enhancements.
PUBLIC INFORMATION
The Combined Sewer Overflow (CSO) Program hosts a
public website and provides updates via Twitter including
up-to-date information to the ratepayers. A Contractor’s
Corner, which identifies upcoming bidding opportunities,
is also on the website.
ADDITIONAL PUBLIC BENEFITSIn addition to the over 56,000 feet of sewer pipe removed,
constructed and/or rehabilitated, the Program construction
projects have provided a total Community Enhancement
value of over $36 million, as identified below.
OUTREACH & STAKEHOLDER ENGAGEMENTInformation is regularly made available to the public

PROGRAM OVERVIEW: GOAL 3
6 Omaha Combined Sewer Overflow Control Program | Implementation Phase
Adams Park outfall structure and wetlands near 36th and Bedford.
Adams Park Wetlands Improvement ProjectThis project consists of wetlands
designed to reduce Combined Sewer
Overflow (CSO) volumes, sewer
backups, improve water quality, and
provide a neighborhood amenity.
The existing combined sewer will be
converted into a sanitary sewer that
will provide sewer separation for the
sub-basin. The new storm sewers
will drain into a new wetland area in
Adams Park.
The Adams Park wetlands and
detention area is designed to provide
the maximum practical stormwater
storage to reduce the size of
future downstream facilities. The
wetlands consist of an area covering
approximately 14 acres, separated
by the park road. A low dam with
an emergency spillway is complete
on the north side of the park,
near Bedford Avenue, to provide
detention volume of up to 77 acre-
feet, which will detain the 100-year
storm event. The wetland facility is
designed to provide water quality
benefits and beautification elements.

for the installation of trees and
landscape features included a
two year maintenance agreement
