Michael C. Van Milligen City Manager 4 2.0 Introduction 2.1 BACKGROUND The City of Dubuque, Iowa is under a Consent Decree according to Case 2:11-cv-01001-EJM, United States of America and the State of Iowa v. the City of Dubuque, IA (N.D. Iowa), Civil Action Number 2008V00041, DOJ Case Number 90-5-1-1-09339, effective June 27, 2011. 2.2 PURPOSE The purpose of this report is to satisfy Section V, Paragraph 12 of the Consent Decree. Paragraph 12 requires the City to submit a corrective action plan for Sewershed 5 by December 31, 2014. Prior to June 27, 2011, the City experienced several discharges of untreated or partially treated wastewater. These events were caused by sharp increases in flow within the sanitary sewer system during and immediately following a rainstorm. To better locate the sources of this issue, the City placed flow meters throughout the city. Depending on location, the meters measured the flow of water from each sewershed over a one to eleven month period of time. Five of the twelve sewersheds metered, including Sewershed 5, were identified as receiving elevated flows during and directly after a precipitation event, leading the City to believe the source is from direct inflow from a pipe or pumped discharge or infiltration resulting from pipe separation/condition issues, allowing infiltration of groundwater. Under the Consent Decree, the City has agreed to investigate five sewersheds over a period of five years (Figure 2-1) with the goal of reducing the sources of inflow and infiltration (I&I). 2.3 CORRECTIVE ACTIONS Per the Consent Decree, the City has employed numerous methods to investigate sources of inflow and infiltration (I&I) including: private property inspections; sanitary sewer smoke testing; manhole condition identification; sanitary sewer closed circuit televising (CCTV) and pipe condition prioritization using the NASSCO assessment and certification program guidelines; and extensive sanitary sewer flow monitoring. Corrective actions based on the techniques and methods identified in this report are provided in subsequent sections of this plan. Section 3 presents the evaluation methods in greater detail, sections 4 through 7 details the corrective actions determined from the source investigation methods; and section 8 provides the budgetary estimates for the prescribed corrective actions. 5 Figure 2-1 Map of Priority Sewersheds for Inflow&Infiltration A, OIE5EL0 pO�EYNR Inflow &I iltration Program _Sanitary Sewers heds To Be Inspected a � 4 KENNEDY RD a—� 5 a a _ '.RE—ST Ti, •. n .,,,__.DERBY GRANGE ,D ebW A- �rYe BypOHYCR Y OIYMPVC HTB SZ � �nn P T S W32'NDgT4 j Sew �Q a fi R s gR sTc 61115' W kG4t1FMANN AVE1T w a VO "09 'WI o_ �� D � s p raiawnr oR "' 9 Q MLLCREST RD i SUHHrvrw - V S - '{ 'MER OR Rr ggy }.

In addition to determining improvements based on the structural integrity of the sanitary sewer system, it has become equally important to reduce the volume of inflow and infiltration (I&I) into the collection system. I&I can have a detrimental effect at the wastewater treatment facility, lift stations operations, and can cause significant damage and create health and safety issues in private properties. The end goal of any I&I reduction method is to see a measurable improvement. The following outlines eight methods that will enable the City to chart a course to successfully monitor and ultimately reduce sanitary sewer overflows, damage to private properties, lift station maintenance, and treatment plant surcharges complementing the actions described in the approved City of Dubuque CMOM. Improvements outlined in later sections of this report are the result of many of the following methods, and will continue to be used to develop future improvements. In addition, a greater emphasis will be placed on flow monitoring to gauge the performance of improvements. 3.1.1 'Low Hanging Fruit' The City of Dubuque's collection system was at one time a combined system with storm sewer flows. The most likely remaining cross connections are floor, driveway, and roof drains; and while not direct, storm sewers located within the same trench or within close proximity to the sanitary sewer are also likely candidates. 3.1.2 Sewer Capacity Evaluation Prior to performing rehabilitative techniques in any of the sewersheds the dry weather flow will be compared to the design capacity of the sanitary sewer, rehabilitating an existing sewer that is already under capacity for the area may not necessarily reduce sanitary sewer overflows. This information will be used to perform further analysis in areas where surcharging still occurs after the initial capital improvement. 7 3.1.3 Clean and Closed Circuit Televise(CCTV)Sanitary Sewers To fully understand the condition for replacement or rehabilitation of the collection system, the sewers are cleaned followed by a CCN inspection. The schedule and frequency is covered in the CMOM program. 3.1.4 Documentation In addition to performing the cleaning and televising, the televising reports are reviewed in detail with documentation of the review catalogued. During an inspection or review of any collection system rehabilitative program it is important to be able to provide evidence of the condition assessment. 3.1.5 Applicability of Techniques Accepted rehabilitative techniques such as sanitary sewer lining and vertical lining of manholes have proven to be successful in reducing inflow and infiltration and while the lining product is a structural product not necessarily an I&I product the industry is recognizing its use in I&I reduction. Care must be taken to obtain and review shop drawings and samples of products to be used. Contract documents and specifications must be written in a manner clearly outlining the intended use and results expected of the products. Sanitary sewer replacement may be necessary if pipe capacity or significant structural deterioration or defects are beyond the capabilities of a structural liner. Storm sewers should also be addressed at this time to ensure sufficient capacity is present with an adequate number of inlets to accommodate the increased local storm and groundwater that may be present where sanitary sewers are lined. 3.1.6 Collection System Flow Monitoring:Permanent and Mobile Units The City is working to understand how flow travels through the City's collection system using flow meters both permanent and mobile units. This is assisting the City in determining key locations in need of improvement and can be used to monitor the area post improvement. While sanitary sewer hydraulic models are used to determine surcharging in a collection system under set parameters, calibration of a model is still required from actual flows. Flows change and are dynamic in nature, and while a model snapshot may provide interim data, a model does not necessarily allow for active management of how and when an overflow may occur, allowing for possible timely prevention. Collection system flow monitoring will take flow metering data and relay in real time system problems, such as fouling of the meter, pipe/manhole surcharging, or other issues that may cause interruptions in service or a health and safety issue. While it will not prevent all sanitary sewer overflows, permanent flow monitoring sites may provide for some level of warning. 8 3.1.7 Private Property Improvements Private property inspections for illicit discharges, not including the service lateral, are currently being conducted under the,Consent Decree and those that were performed under other studies are invaluable in determining to what extent the private sector may be contributing I&I to the collection system. For an external source of I&I coming from a private property, such as a driveway, the area draining to the driveway may determine the level of contributing risk. In some cases, a private property driveway drain may not easily be disconnected as it may drain a large drainage area due to lack of inlets and storm sewers and disconnecting the drive way drain may lead to significant private property damage. The City has approved a financial assistance program which combined with "green" technology efforts may present long term solutions for private property improvements. Private sanitary sewer service laterals making up almost half of any collection system need to be addressed in tandem with local public sewer improvements. Based on soil, natural spring locations, and groundwater elevations, public sewer improvements can lead to greater problems for a private service lateral. Lateral replacement or rehabilitation can be very costly, and so with any public sewer lining contract consideration should be made as to whether is beneficial to install a partial or tee liner especially where there is a non-factory lateral connection. 3.1.8 Ordinance and Policy The Sanitary Sewer System, Capacity, Management, Operation and Maintenance Program (CMOM) as adopted by the City of Dubuque, covers much of what is described in the above Techniques. CMOM also includes applicable City of Dubuque ordinances and policies, it is important to keep these relevant, up to date, and enforceable for new and existing development in the City's continued efforts to reduce inflow and infiltration. 3.2 SANITARY SEWER EVALUATION METHOD FOR REHABILITATION/REPLACEMENT In addition to the previous methods, the City is supporting a sanitary sewer priority grading system based on accepted industry procedures offering a proactive approach to eliminating sanitary sewer overflows (SSOs). The system allows City staff to pinpoint areas within the gravity sanitary sewer pipes that need a more thorough investigation due to the critical nature of the location, physical attributes of a pipe section, the structural integrity of the pipe, and operation and maintenance needs of the pipe. 3.2.1 Condition Grade The condition grade of a pipe is determined using structural and operation and maintenance (0&M) grades acquired by closed circuit television (CCN) evaluation of the pipe. As a pipe is televised, City staff uses the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and 9 Certification Program (PACP) to code the pipe. Any structural and 0&M deficiencies in the pipe are noted by certified PACP operators. Since 2010, the condition coding for any pipe recorded by CCTV is automatically done by PipeTech°software which uses the PACP condition grading system. The PACP grading system code matrix can be found in the NASSCO PACP manual and ranges from 0 to 5. A grade of 0 means there is no structural or 0&M deficiency noted for the pipe whereas a grade of 5 would indicate a structural deficiency possibly combined with an operation and maintenance deficiency such as excessive calcification or roots. The condition grade is the maximum of the structural and 0&M grades assigned to the pipe. 3.2.2 Criticality Grade The criticality grade is split into two categories: "Probability of Failure" and "Consequence of Failure." Specific analysis is performed on each category before they are combined into the criticality grade. Eleven factors are divided among the Probability and Consequence categories: 1. Material 2. Age 3. Pipe slope 4. Maintenance 5. Proximity of the pipe to a recorded SSO 6. Pre-defined road capacity levels 7. Priority locations within the City 8. Proximity of the pipe to rivers and water bodies 9. Proximity of the pipe to railroad tracks 10. Pipe diameter 11. Pipe is located under a building. 3.2.3 Priority Grade The priority grade is the final grade for the pipe and determines the order in which the pipes should be investigated further. These investigations include but are not limited to further observation of the pipe, repairs, or replacement. The priority grade is dependent on both the condition grade and the criticality grade. The condition grade has been assigned greater emphasis than the criticality grade because the condition of the pipe provides more information on if the pipe is likely to fail due to structural issues. The pipe priority grade follows the recommendation in "Guidelines for Condition Assessment and Rehabilitation of Large Sewers" paper published in 2001 by the National Research Council of Canada. 10 :3.2.4 Corrective Actio►►s In prior Corrective Action reports for Sewersheds 11 and 12, the City made recornmendations to improve or replace pipes with priority grades of four and five. This follows the recommendation established by the National Research Council of Canada in "Guidelines for Condition /Assessment, and Rehabilitation of Large Sewers". This information is now aligned with the results and analysis obtained from the flow monitoring data. The corrective actions listed in this report are based on the procedures listed herein, with the first priority given to grade four and five pipes that have been identified for improvement or replacement within an area determined by flow metering to have excessive inflow and/or infiltration. 11. 4.0 Private Property Inspections 4.1 INSPECTIONS There are 1,572 private properties in Sewershed 5 per the City's records. City inspectors have conducted 1,554 (98.85%) private property inspections to identify roof drain discharge locations, the presence of any stairwell or driveway drains, and the presence of a sump pit/pump on site. A passing inspection would indicate no connections of clear water to the sanitary sewer system. A failed inspection would indicate an improper connection of clear water into the sanitary system, which could include roof drains connected to the sanitary sewer; a stairwell or driveway drain which is connected to the sanitary sewer; or a sump pump or floor drain plumbed directly to the sanitary sewer. In Sewershed 5, of the original 1,572 properties 18 have not been inspected. The City follows a multi-step procedure to provide many opportunities for the property owner to arrange an inspection. The first step is a letter notifying the property owner of the Inflow &Infiltration Reduction Program, a pamphlet is included explaining the program. If the City is not contacted, the second step is a follow up phone call, and the third is a door hanger and 'cold-call'. If after the three attempts to contact the owner, the City is not successful, a Final Notice letter is sent along with a second copy of the pamphlet explaining the nature and necessity of the program. The Final Notice letter also informs the property owner that the City may obtain an Administrative Search Warrant to complete the inspection. If no response, the City sends the property owner a Notice to Obtain an Administrative Search Warrant, and finally the City will obtain the search warrant to complete the inspection. 4.2 PRIVATE PROPERTY CORRECTIVE ACTIONS Each improper connection observed during a private property inspection results in a failure notice. The property owner then has 30 days to correct the improper connection, at which point a re-inspection of the property is conducted to verify that the improper connection is eliminated. If the improper connection is not corrected, City inspectors remind the property owner of the required work; request a timeline to correct the improper connection; and offer suggestions on how to efficiently and economically correct the connection. If a property owner chooses not to correct an improper connection, the City will pursue legal action against the property owner pursuant to City of Dubuque Code of Ordinance Sections 13-2A-1, 13-2-9. 12 In Sewershed 5, there were 68 failed private property inspections; these are listed in Table 4-1, of which 58 have been corrected. The Sewershed also presented a new issue, a sump pit without a sump pump. The area was more recently developed and properties were permitted to have pits installed without sump pumps. The City has deliberated the risk of having a pit without a pump and has prepared a document for property owners where options are presented. The proposed options are as follows: a. Install a sump pump and properly plumb piping to the exterior of the home, subject to City of Dubuque inspection and documentation, b. Provide the City of Dubuque with a certified Professional Geologist soils and groundwater report determining the soil types and natural or seasonal groundwater levels for which a complete drain tile or pipe system is not required. c. Execute an agreement acknowledging the existence and requirements of the consent decree between the City of Dubuque and the Environmental Protection Agency, that the sump pit located within their home has never been used nor is it their intent to ever use the sump pit, they understand the City ordinances on illegal discharge, and they understand the risks associated with illegal discharge. There are 75 properties that have a pit without a pump. In the event, all properties were to opt for option C, the City would continue to flow monitor directly downstream of the subdivision and analyze flow data for 'pumped' flow indicative of a pump being installed in a pit, at which time option C would be no longer valid and the property owner would be required to install a sump pump with fixed piping discharged to a location that would not negatively impact the surrounding area. Table 4-2 lists those with a sump pit and no pump. Some improper connections, such as stairwell drains, can require complex and costly corrections for property owners. The City is sensitive to the economic hardship these corrections may cause and the need to eliminate these significant connections to the sanitary sewer. Therefore, a cost-share program has been established for the City to partner with property owners. City staff will continue using the cost-share program to balance property owner costs and Consent Decree requirements. (The City retains the right to rescind the cost-share program at any time for good cause including funding availability). City staff continues to work with property owners to address those improper connections not yet corrected below, therefore no specific schedule for correction is shown. 13 Table 4-1 Failed and

In August of 2012, two crews consisting of three to five city employees conducted smoke testing. They identified both private property and public sewer utility issues including possible sanitary sewer system joint and pipe failures, possible storm sewer catch basin connections, along with possible cracks, leaks or breaks in a property owner's sanitary service laterals. As smoke testing is a widely visible inspection of the sanitary sewer system, the City conducts an extensive public relations effort to prevent concern or confusion associated with visible smoke. Public information notices are published in the local newspaper and on the City of Dubuque's website prior to testing. Along with the public notices, each resident in the area being smoke tested receives a letter in the mail along with a door hanger 24 hours prior to testing. The information is distributed to inform residents of the smoke testing's purpose and timing.The notice also reminded residents to fill unused drains with water to avoid having smoke enter their homes. Fifteen gallons of liquid smoke was used at key manholes throughout Sewershed 5. At each location, a blower was placed over the opening of the manhole, introducing air and smoke into the sanitary sewer system,thereby forcing smoke through the connected sewer lines. The supply of smoke was continuous until the area was thoroughly examined and any defects recorded. Each smoke testing site was able to cover a range of approximately 500-1000 linear feet in each direction. The weather during testing was overcast and sprinkles were in the area.The soil conditions were dry and winds were calm. 5.2 OBSERVATIONS AND CORRECTIVE ACTIONS In Sewershed 5, smoke testing manholes in and around the Carter Road detention basin was found to have the most defects.Throughout the residential areas, smoke was observed coming from cracked and missing cleanout covers and across lawns where there is the possibility of broken or cracked sanitary sewer laterals. Smoke was also detected in and around manholes in timber areas and at manholes with open pick-hole lids. One hundred and thirty seven (137) defects were identified in Sewershed 5. Of the 137 defects 25 were on private property and 112 were in the public right of way. Photos were taken of each and mapped. City staff has classified the results into categories to be further investigated and repaired: 21 private property investigation and repairs; private property lateral investigation and repairs, and public sanitary sewer investigation and repairs; 5.2.1 Private Property Table 5-1, lists the 25 private property sites showing possible private property defects along with the observations made during smoke testing and the corrective action required. Identifying the source of I&I in a sanitary sewer lateral can be especially difficult and expensive for an individual property owner, three (3) of the 25 were determined to have smoked due to private sanitary sewer lateral issue. In the City's budget, funds may be available for financial assistance for work completed on a private sanitary sewer lateral, each year a request is made to fund these line items, however they are subject to availability and are on a first come first served basis.

Table 5-2 shows sanitary sewer system defects where there are possible broken or cracked pipes, vented manhole lids, and possible inadequately sealed manholes. Section 6 of this report outlines sanitary sewer manhole improvements. Further evaluation of the system beyond those defects detected during smoke testing presented manholes improvements due to the location of the manhole, this is further explained ins Section 6. Sanitary sewer replacement or rehabilitation is detailed in Section 8 and is based on the smoke testing observations, CCN sanitary sewer reports, and flow monitoring data.

Manholes listed in this section were either observed as having defects during smoke testing, a visual inspection, or both. All observations are recorded in the City's GIS database. Smoke testing and visual inspections enable City staff to document faulty characteristics including manhole lids with open pick holes and locations where sealant material was either missing or had deteriorated over time allowing smoke to come to the surface. Key areas identified during smoke testing and flow metering are at the Carter Road detention basin and in sub basin 5-4. Unlike Sewersheds 7, 11, and 12, Sewershed 5 consists of newer development with concrete manholes. No brick manholes were noted during smoke testing or visual inspections. 6.2 CORRECTIVE ACTIONS Of the 530 manholes in Sewershed 5, one hundred and twenty-two (122) were determined to be in need of repair. The City will begin repairs or rehabilitation of 100 manholes per Table 6-1, with a tentative completion date set for the following budget cycles and as funding permits. Twenty-two manholes are located in the Carter Road detention basin area and have been separated into Table 6-2 with a sooner completion date.

The City continues to flow monitor Sewershed 5 at a master meter location at 45 W. 32nd Street to observe any changes not originally detected during the required observation time period. The Sewershed 5 sanitary sewer drainage area was established per the area shown below with flow exiting at Carter Road and W. 32nd; however, the Sewershed would not enter another Sewershed until it reached the intersection of Central Avenue and W. 32nd Street hence the revised map showing the master meter location at 45 W. 32nd Street.

In two cases, flow meters were doubled in sub-basins 5-1 and 5-3 as sewer lines converged prior to leaving a key area such as the Carter Road detention basin which was monitored at Carter&W. 32nd flow meter in sub-basin 5-1. 7.2 SEWERSHED 5 FLOW DATA ANALYSIS Documentation supporting the following analysis may be found in Appendix A and B. Appendix A includes a location map showing the flow meter sites and metered flow data for the April 18th rain event and Appendix B includes the metered flow data for the July 8th rain event. Six flow meters were deployed into Sewershed 5, one master and five upstream at locations that would intercept main feeds prior to the master meter. The master meter is labeled 45 W. 32nd Street. The meter at 1951 W. 32nd measures flow from sub-basin 5-2 and part of 5-1; and the meter at Carter & W. 32nd measures flow from the two meters flanking the Carter Road Detention basin which takes flows from sub-basins 5-5, 5-4, and 5-3. In 2013, data was collected between April and October. Throughout the data collection period a seven-day dry timeframe was captured providing a summer average dry weather flow (ADF) rate of 0.51MGD for the master meter at 45 W. 32nd; the summer ADF for Carter & W. 32nd is 0.42MGD; and the summer ADF for 1951 W. 32nd is 0.02MGD. During that time, two measurable storm events were captured; one on April 18th and a second on July 8th where the detention basin was in operation and the sanitary sewer manholes were below standing storm water. The following is a summary of the data collected: Summer April 18th,2013 July 8th,2013 Average Dry (Rain Event: Total (Rain Event: Total Location 2.65in Peak 0.1in Peak 0.45in Weather Flow � � 1.89in� ) Rate ADF(MGD) Max.

This is common for raw or unaltered flow data. There may be several reasons for the discrepancy, such as adjustments made in setting the flow line level (depth of flow in the pipe); variations in diameter measurement as some ovality of the pipe may exist and typically diameters are entered as whole values; or there is a significant amount of exfiltration. As such, the data is analyzed in terms of magnitude along with the numeric flow data and the meters are inspected weekly for debris and any changes in flow depth. This enables the data to more closely reflect actual conditions in the field and calibration to occur as frequently as needed. In both storm events, the peak flow is relatively instantaneous, which is typically indicative of direct inflow. At sub-meter Kaufmann and Trygg the area monitored is sub-basin 5-4. The area is largely residential with business and light commercial. During both storm events, the increase in flow rate was approximately 1.OMGD, indicative of inflow based on the trending; however review of the televising reports shows moderate but not excessive joint or pipe issues. A focus on the manholes in the sub basin is the direction taken during this reporting and corrective action period, this work is reflected in Section 6.. The flow from 5-4 proceeds through sub basin 5-3 and is measured again as it passes through the meter at Carter Rd DB South. During the April rain event, the meter at Carter Rd DB South measured 3.16MGD. The July event was presumed to not record correctly as it registered 1.84MGD. It is speculated to not be accurate as a filter in the flow meter was not functioning correctly and had plugged, upon further review this may explain the increase in flow shown on the April 18th rain data for Carter Rd DB South. At the time readings were taken in both April and July, the filter problem was not detected until the winter months, when the flow meter was showing incorrect level (depth of flow) readings. In speaking with the manufacturer, Teledyne ISCO, there was a flaw in the filter that allowed moisture to enter the cap where the filter was housed causing it to plug, and in the winter, freeze. When the filter defrosted and dried, the levels returned to normal but made for erratic data collection and calibration errors. The manufacture has since redesigned the cap which allows air to pass through the filter and the pressure sensor to work and maintain the depth of flow measurement correctly in the pipe leading to increased reliability in using the flow data. The newer flow meters purchased during 2013 and 2014 had the newer style cap and did not show any filter issues. As flow data is collected from 5-5 at Carter Rd DB West the flows increase, but not to the same magnitude as flows from the south. With final data collection at Carter & W32nd downstream of the Carter Road Detention Basin, the flows reflect significant inflow increasing an additional 3.OMGD, assuming a 0.2-0.5MGD inflow from basin 5-5, the detention basin area is estimated to be adding 2.5MGD of inflow. As such, efforts during the 2014 construction season were directed to address the sanitary sewer system as it passes beneath the detention basin. Further corrective actions based on these findings, the smoke testing results, private property inspections, and the NASSCO pipe results are reported in Section 8 Sanitary Sewer Rehabilitation. 38 8.0 Sanitary Sewer Rehabilitation and Replacement 8.1 SANITARY SEWER INVESTIGATION There are approximately 107,757.00 lineal feet or 20.4 miles of sanitary sewer in Sewershed 5. In evaluating the sanitary sewers in terms of the NASSCO pipe condition rating, smoke testing data, local knowledge, and flow monitoring data, the area most critical in terms of inflow was the area located directly beneath the Carter Road Detention Basin, sanitary sewers downstream of the basin along Carter Road and sub basin area 5-3 upstream of the detention basin. The flow monitoring data in addition to the local public works knowledge and smoke testing provided sufficient information with which a capital improvement plan could be derived for the Corrective Action listed in Section 8.2 below. Further corrective actions may be necessary as continued flow monitoring may identify additional improvements, which will be placed on future budget cycles. 8.2 CORRECTIVE ACTIONS Based on the sanitary investigations, the City is recommending the rehabilitative technique of cured-in-place-pipe (CIPP) for approximately 13,444 lineal feet along with any necessary point repairs and sanitary sewer lateral liners. Table 8-1 lists the location and pipe lengths scheduled for rehabilitation. The table includes all work scheduled for the upcoming budget periods and the work completed during the 2014 construction season.

The plan is subject to approval by the US EPA and Iowa DNR. 9.1 FUNDING The Capital Improvement Program (CIP) Budget represents the City of Dubuque's five year physical development effort. The CIP attempts to address a variety of needs, which the City must meet if it is to maintain its physical facilities, meet its service commitments, and provide for its future development. The CIP Budget reflects the City's comprehensive plan and the goals and priorities established by the City Council. The first year of the five-year CIP Budget goes into the budget for the next year and deserves the most attention. The CIP Budget is updated each year so the City Council has the opportunity to change the next four years and add a new year. At this time, the CIP Budget request is sufficient to fund the corrective actions identified in this plan. However, the City reserves the right to adjust or remove corrective actions from this plan based upon funding, further investigation, and future I&I-related priorities in other sewersheds. 9.2 BUDGET The following table, Table 9-1, lists the associated costs of the work necessary to progress toward reducing inflow and infiltration into the sanitary sewer system.
