Omaha Combined Sewer Overflow Control ProgramImplementation Phase

MRWWTP was built in 1964 and treats an overall average of 25 MGD of wastewater. When the CSO Program improvements are completed, this facility will handle up to 150 MGD.

New Municipal Headworks for the Missouri River WWTP Improvements–Schedule B1 project

Significant improvements to Missouri River Wastewater

Treatment Plant (MRWWTP) have been completed to

improve water quality in the Missouri River. Two of the

three construction projects are nearly complete. When

all three projects are complete, the MRWWTP will

provide treatment for high-strength industrial waste

during wet weather events (Schedule A), the primary

and secondary treatment capacities will be increased to

150 MGD and 64 MGD (Schedule B1), and flows above

64 MGD will be disinfected and dechlorinated prior to

discharge to the Missouri River (Schedule B2). In addi-

tion to the significant improvements to water quality,

the project will also reduce odor impacts to the public

and achieve resources recovery/energy generation from

the additional solids removed from the waste stream,

and replace aging plant infrastructure. Schedule A is in

operations, Schedule B1 is 98% complete, and Schedule

B2 will be in operation by mid-2019.

With the maximizing of flow to the MRWWTP from

upstream projects, disinfection of the discharge from

Combined Sewer Overflow (CSO) 102, and separate

treatment of the high-strength industrial waste, the

reduction in pollutant loading to the Missouri River is

approximately 50%.

In addition to the direct improvements to the MRWWTP,

the Bank Stabilization project received construction

notice-to-proceed in March. This project is necessary to

stabilize the bank to prevent damage to the treatment

plant as well as allow for construction of the treatment

elements under the B2 project in this area.

Additional information on this project can be found in the Appendix.

PROJECT SPOTLIGHT

1st Quarter 2016

HIGHLIGHTS » Saddle Creek RTB Value Engineering analysis is projected to be complete

in April to identify cost saving opportunities. Bids were opened for the

Saddle Creek Early Soils construction project, which was substantially

under the engineer’s estimate. Construction NTP was given in March.

» All work at Lauritzen Gardens is complete. Final paperwork is being

processed for the pond lining project.

» Hitchcock Park Green Infrastructure Project was broken out of the 42nd

and Q Street project and is expected to bid late this fall for a summer 2017

construction notice to proceed (NTP.) This has opportunity for increased

small emerging business (SEB) participation and cost savings.

» Gilmore Avenue Detention Pond & Albright Park Landscaping is expected

to bid late this fall, for a spring construction NTP.

» Communicated with Nebraska Department of Environmental Quality

(NDEQ) regarding concerns related to higher project costs for Missouri

River Waste Water Treatment Plant (MRWWTP) Improvements, Minne Lusa

Stormwater Conveyance Sewer, and Saddle Creek Retention Treatment

Basin (RTB.)

Adams Park Landscaping Improvement project is nearing final completion. The above rendering depicts the completed project with plant selections.

HIGHLIGHTS

2020

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 3: Community Acceptance.

Maintain continuous public dialogue,

provide information and pursue

opportunities for multiple benefits in

CSO Solutions.

Goal 2: Economic Affordability.

Minimize cost impact to ratepayers

by completing CSO Control Options

within or under budget.

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.

GOALSIn order to comply with the

requirements of the Clean Water

Act, the United States Environmental

Protection Agency (EPA) CSO Control

Policy of 1994, and Administrative

Consent Order with the NDEQ, the

City of Omaha developed a Long

Term Control Plan (LTCP) that outlines

an action plan 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 constructed, operational and

are implemented in a cost effective

manner by 2027.

CSO PERMIT IS VALID THROUGH OCTOBER 2020

The CSO permit was recently approved by

NDEQ in September 2015 with a reduction

in requirements that reduce the cost to the

city and in support of Omaha’s Program. The next required CSO permit renewal is in October 2020.

CONSTRUCTION COST STATISTICS

LEGISLATIVE ACTION IN SUPPORT OF THE PROGRAMLB 413 was recently passed to allow NDEQ to consider financial capability, affordability, future growth, other investments and other relevant economic/ social/ environmental conditions when issuing an National Pollutant Discharge Elimination System (NPDES) Permit. This will be evaluated for its benefit to the CSO Program.

VALUE ENGINEERING TO IMPLEMENT COST-EFFECTIVE SOLUTIONSAdditional funding sources have been identified along with identified construction cost savings.

RATEPAYER ASSISTANCEWhen the 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 January 2015 through March of 2016, over $930,000 has been provided in assistance. 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.

Economic Affordability is the minimization of the cost impact to the ratepayers.

Construction costs have been contained, as shown in the following metrics.
