MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: Stephan M. Brand, Public Works Utility Bureau Manager
DATE: June 18, 2018
RE: Approve and Submit 2017 Wisconsin Department of Natural Resources (WDNR) Compliance Maintenance
Annual Report/Wastewater Treatment Plant
BACKGROUND
The City of Oshkosh is required by the WDNR as part of the Wisconsin Pollution Discharge Elimination System Permit to
complete a Compliance Maintenance Annual Report. This report outlines the performance of the Wastewater Treatment
Plant and sanitary sewer collection system for the previous year. The results reflect the dedication of the Wastewater Utility
staff and their commitment to protecting the community's public health and water environment. This report needs to be
formally approved by the Common Council for submittal to the WDNR by June 30, 2018.
ANALYSIS
The report is broken down into sections that address specific areas of performance for the wastewater system. Based on
the responses in each section, a score is determined and a letter grade is given based on the score. This grade is used by the
WDNR to determine the need for improvements to the wastewater treatment system. A letter grade of A or B does not
require any action be taken based on the information provided. The following is a brief summary of each section:
Influent Flow and Loading: This section looks at plant flow capacity and treatment ability based on the design of the
facility. Our highest flow month for 2017 was April with a monthly average flow of 17.42 million gallons per day, which is
49.8% of our design flow of 35 million gallons per day. Normal months are closer to 36% of design flow with an average of
12.7 million gallons per day. The treatment capacity is based on Biochemical Oxygen Demand (BOD) in pounds per day.
Our highest influent loading monthly average was 15,871 pounds in the month of June. Our design loading is 33,360
pounds, which puts us at 47.6% of our design loading for the facility. This section also includes questions on flow meter
calibration, the Sewer Use Ordinance, Septage Receiving (Hauled Waste Delivered to the Plant), and the Pretreatment
Program. No issues were identified in any of these areas. Based on these responses and the available capacity of the facility,
this section scored a letter grade A.
Effluent Quality — BOD, TSS (Total Suspended Solids) Ammonia and Phosphorus: These sections look at the quality
of our treatment individually for each of these parameters based on our permit requirements and testing and analysis. All
reported values were within required permit limits. The sections for BOD, TSS, Ammonia, and Phosphorus each scored a
letter grade A.
Biosolids Management: Solids are generated from the treatment process due to the growth of microorganisms that are
used for the treatment of wastewater. There is a separate process used to treat this material as it is removed and turn it into
a product that can be beneficially re -used as fertilizer on approved agricultural land. This section of the report evaluates
the treatment process and management of the biosolids in compliance with the permit requirements. All requirements
were met and this section scored a letter grade A.

18.docx
Staffing and Preventative Maintenance: This section asks general questions about plant maintenance procedures, record
keeping, and staffing levels. There were no issues identified with either plant maintenance or staffing and this section
scored a letter grade A.
Operator Certification and Education: The WDNR requires wastewater facilities have state -certified operators on staff to
operate and manage the facilities to meet the requirements of the Wisconsin Pollutant Discharge Elimination System Permit.
Certified operators are required to attend approved conferences and training to meet continuing education requirements
for the certification renewal every three (3) years. We have certified operators on staff who are certified at the appropriate
levels for the wastewater treatment facility. This section scored a letter grade A.
Financial Management: This section looks at the financial aspects of the utility and is done with the assistance of the
Finance Department. In addition to rates, it looks at the funding in the Equipment Replacement Fund, which is required
as a condition of the Clean Water Fund when financing projects through the Clean Water Fund Financial Assistance
Program. We have also started including projects listed in the Capital Improvements Program (CIP) in the Future Planning
section to show future potential spending requirements. There were no issues identified and this section scored a letter
grade A.
Sanitary Sewer Collection Systems: This section is completed using information provided by the Streets Division and
Engineering Division, based on the activities reported for sanitary sewer maintenance and construction in 2017. Based on
the activities reported, this section scored a letter grade A.
Efforts continue to reduce clear water entry into the sanitary sewer system. Flow monitoring and inspection of manholes
for rehabilitation continues, along with televising to identify sanitary sewers in need of replacement. Sanitary sewer repair
and replacement projects are ongoing and are reflected in the CIP. The Capacity Management Operations and Maintenance
program has been fully implemented and continues to provide opportunities to update and refine operations and
maintenance activities related to the sanitary sewer system. The System Evaluation and Capacity Assurance Plan has also
been completed and includes a City-wide sanitary sewer model. This model continues to be used to analyze the capacity
of the sanitary sewer system in specific areas under various dry and wet weather scenarios to determine where there may
be capacity issues and to look at corrective action opportunities. It is also being used extensively in CIP planning and area
planning studies for future sewer requirements.
FISCAL IMPACT
There is no fiscal impact to the City related to this report.
RECOMMENDATIONS
I recommend approval of the 2017 Compliance Maintenance Annual Report for submittal to the WDNR.
Approved,
Mark A. Rohloff
City Manager
