Van Milligen MCVM/jh Attachment cc: Barry Lindahl, City Attorney Cindy Steinhauser, Assistant City Manager Bob Green, Water Department Manager Ken TeKippe, Finance Director THE CITY OF Dubuque a Masterpiece on the Mississippi Zoa~ TO: Mike Van Milligen, City Manager FROM: Bob Green, Water Department Manager~~ Ken TeKippe, Finance Director ~~ /~~J~`~'~ SUBJECT: Water Meter Review and Testing Phase II DATE: March 26, 2009 BACKGROUND The enclosed report details information on the Water Meter Review and Testing Phase II completed in March 2009 by HDR Engineering and M.E. Simpson Co. The report is a continuation of the Water Meter Review and Testing Phase I completed in November 2008. This phase of the study focused on reliability of water meters installed in the past five years. The first phase focused on aged water meters. The project included testing samples from all meter sizes in residential, commercial and industrial use. DISCUSSION The Phase I and II results support continuation of a water meter replacement program. The last major water meter change began in the late 70's and was completed in the early 80's. The completion of additional Phase II testing of 152 meters determined a realistic view of the condition of our complete inventory of meters. Retrofitting of our current meters is not desirable. Replacement parts are becoming increasingly difficult to obtain for existing meters. In addition, meter technology is changing so rapidly that our existing meters are becoming obsolete. The combined estimate of Phase I and Phase II test results project a range of annual revenue loss of 5.4% ($530,000) to 6.9% ($676,000). The capital payback range using net present value computation is 10-13 years. The payback changed from Phase I due to the lower revenue loss and using higher 2009 estimated equipment replacement costs: Based on overall age of meters, it is anticipated that the revenue loss is closer to the higher range and thus the payback period closer to a 10 year estimate. The capital payback is detailed in the enclosed executive summary (pages 2-3). Operating costs will be positively impacted by the installation of a fixed radio network meter system. The outsourced monthly meter reading will be phased out (currently $142,000 annually). Accountability will be improved with the fixed radio system due to meter reads in the office versus in the field, on demand meter reading and the option of remote turn on/turn off. Repair costs should dramatically decrease compared to what the City currently experiences. In addition, providing citizens with accurate meter reading will encourage responsible use of water resources. RECOMMENDATION The next phase of the project involves the City soliciting proposals from firms to assist in developing plans and specifications for a water meter change out program. Appendix 7.3 of the report provides a detailed typical consultant draft procurement/implementation project approach. The request to solicit proposals is time sensitive to expidite the project should the City receive stimulus funds. The project funding is planned from the State Revolving Fund Loan. ACTION STEP We are requesting your approval with authorization to proceed with the next step of this program in soliciting a firm in creating the plans and specification with this program. Funding for this program is part of FY'10 and FY'11 CIP budgets. We are available to discuss the report and our recommendation at your convenience. KT/jg Enclosure THE CITY OF L~U~ E Mnsterpieec oii the' is~is~iF~pi Final Water Meter Review and Testing Phase Two March 2009 Prepared by: ' HDR Engineering, Inc. ~ 1.U Executive Summary During July through October of 2007, HDR performed a Water Meter System Evaluation for the City of Dubuque. Recommendations for future improvements and upgrades to the water meter system were developed. A recommendation from the study was to perform testing and evaluation of the existing water meters due to the large portion of the City's meter population nearing or past the expected life span of approximately 15 to 20 years. As meters age, they become worn, which over time reduces or slows the overall registration of the meter. This meter inaccuracy influences water consumption measurement which in turn reduces collected revenue. In order to determine the magnitude of potential meter inaccuracies within the City's meter population, HDR was selected in cooperation with M.E. Simpson to conduct a Water Meter Review and Testing program. The program tested a sampling of Dubuque's meters to identify typical meter inaccuracies resulting from their age and application. Based on the meter testing conducted in September through October of 2008, a significant number of small and large meters failed testing: 35.7% of the small meters (5/8-inch to 1-inch) and 40.3% ofthe large meters (1-1/2-inch to 8-inch) failed, indicating that meter replacement is needed. The test results also indicated that some of the failed meters were less than five years old. To further evaluate the performance of meters less than five years old, a Phase Two meter testing study was conducted in February through March 2009 that focused primarily on mid-sized and large meters less than five years old. The Phase Two testing indicated that 15.4% of small meters (5/8- inch to 1-inch) and 9.7% of large meters (1-1/2-inch to 6-inch) failed. As expected, the number of meters that failed was less than in the Phase One testing, although some results were notable given the low age of the meters. Considering the combined Phase One and Phase Two results, a significant number of relatively new large compound type meters failed, indicating that a meter testing and maintenance program would be beneficial once new meters are installed. It is not cost effective to repair small meters, although testing a sample of the small meter population is useful to determine meter accuracy, lost revenue, and the need for future meter replacement. Large meters measure a much higher consumption volume with higher associated revenue than a small meter. For example, a single turbine meter may measure 500 to 1,000 times more water than a residential meter. Although the number of large meters in the system is small, a regular preventative maintenance and repair program would provide significant benefits through extend meter life, proper accuracy and associated maximized water revenue. The additional testing would require additional staff or outsourcing to a contractor. A revenue analysis was conducted based on the combined Phase One and Phase Two testing results, meter size, and consumption information. The revenue analysis estimates that 138,000 cubic feet of water or 5.4% of annual consumption is not recorded by the water meters. The volume of water not recorded results in a projected loss of water and sewer revenue of approximately $530,000 for fiscal year 2009. This value is likely lower than the actual value since the majority of the meters tested for Phase Two were less than five years old and meter failure and inaccuracy increases with age. The meters tested for Phase One represented a wider range of meter ages and based on the Phase One results 6.9% of annual consumption is not recorded by the water meters, resulting in a projected loss of $&76,000 in lost water and sewer revenues for fiscal year 2009. Over time, lost revenues will increase as meter failure, inaccuracies and water rates increase. HDR Englneering, Int. Dubuque Water A%leter Review and Testing 2 The high number of meters out of specification and the associated annual lost revenue support implementing a meter change-out program. The 2007 Water Meter Plan and System Evaluation recommended installing a fixed radio network meter system as the lowest cost alternative. A fixed radio network allows remote reading of water meters, eliminating the need for labor intensive manual meter reading. From the 2007 Water Meter System Evaluation cost model, the 20 year present value cost of a fixed radio network water meter system will be approximately $6,850,000 (2009 dollars) and includes the cost of new water meters, radio equipment, computers and other hardware. Based on the combined Phase One and Phase Two curl•ent lost revenue and the estimated 2007 cost updated to 2009 dollars for a new fixed network meter system, the payback period would be approximately twelve years. Based on the Phase One meter testing results, the payback period would be approximately nine years. Table 1-1 shows the preliminary payback period for the fixed radio network meter replacement program. The lost revenue figure will be compounded over time as existing meter accuracy decreases and water rates increase. Table 1-1 Revenue Recovery for Fiscal Year 24Q9 Rates The fixed radio system requires fewer employees for meter reading and results in lower operating and total costs than the existing system contracting with Aquila to read the meters. The fixed radio system alternative assumes City staff will be responsible for the radio network, billing and will continue to perform routine meter maintenance and replacement as is currently done. There is not expected to be any change in City staff levels from the current system to the fixed radio network system. However, the cost of contracting with Aquila will be saved. Currently, the annual cost for Aquila is about $142,000 and is expected to increase approximately 3% per year due to anticipated inflation. A limited number of the City's newer meters in good working condition could be retrofitted to work with a fixed radio meter system. Retrofit is not recommended for smaller meters due to the low marginal cost of meter replacement compared to the cost of meter retrofit. In addition, if all small meters are replaced, the system would be standardized around one type of meter with similar age that reduces inventory, and improves scheduling of future replacement. Retrofit and repair could be beneficial for some large meters, although further evaluation will be required to determine if retrofitting is cost effective. In addition to direct cost savings, there are many operational and non-direct financial benefits of moving to a fixed radio network meter system compared to the existing meter system. Fixed radio network meters improve customer service and staff efficiency by allowing real-time meter reading. Water meter remote registers on the side of buildings will be removed and problems with meter accessibility and the need to enter a home or business for meter reading will be eliminated. The large amount of data that can be easily and remotely collected with a fixed radio network system will allow City staff to efficiently develop water system hydraulic models, track water consumption trends and plan for future water system requirements. Parts and repairs for some of the older existing water meters are becoming more difficult and new meters will allow for easier meter repair work. HDR Englneering, Int. Dubuque Water A%leter Review and Testing The high number of meters out of specification, annual lost revenue, and other benefits support implementing a meter change-out program. Based on a meter asset life of twenty years and a payback period of approximately ten years, there is a positive payback period and a meter replacement program is recommended. 2.D Meter Testing Program 2.1 Meter Testing Goals and Objectives The water meter review and testing program was designed to locate inconsistencies in the metering of water and to identify meter accuracy problems resulting from age of meters, and application. The review helps the development of acost-effective replacement schedule for water meters and provides recommendations for the correction of the identified problems. Phase One of the meter testing program was completed in November 2008 and focused on a broad cross section of the meter population based on meter size and age. The results of the Phase One meter testing indicated a higher than expected failure rate among some newer meters. To further evaluate the performance of newer meters, additional meter tests (Phase Two) were conducted that focused primarily on meters less than five years old. Select information for various meter accounts was copied from the City's database for review and evaluation. These data were used to put together a cross section of meters based on their age, size, and type. Based on patterns of consumption and meter record information, an application evaluation was performed. This evaluation compared the historical meter use to American Water Works Association (AWWA) standard specifications relating to proper meter size and application as well as age and wear. 2.2 Description of Water Meter Technologies Tested The following sections briefly describe three common types of water meters. 2.2.1 Positive Displacement Meters Positive displacement meters are typically used in residential and commercial applications with low flow rates and sizes of less than 2-inches. Displacement meters work by using water to "push" or displace a piston or nutating disk connected to a measuring system. Displacement meters are commonly used in applications with flow rates of less than 50 gallons per minute. High flow rates in displacement meters can create high head losses that make their use impractical for large meters. 2.2.2 Compound Meters Compound meters are used for applications that require measurement of a wide range of flow rates. A compound meter consists of two separate meters and a check valve that controls flow to each meter. The low flow meter is usually a positive displacement meter and the high flow meter is often a turbine meter. As flow rates increase, a check valve opens to divert a portion or all of the water to the high flow meter. The readings from each meter are added to determine the total water consumption. Compound meters can experience inaccuracy during "change-over" when the check HDR Englneering, Int. Dubuque Water A%leter Review and Testing valve is partially open and flow is diverted to both meters. It is important to test compound meters over a wide range of flow rates. Compound meters tend to require more maintenance than other meter types. Inaccuracy at high flow rates caused by either a faulty check valve or faulty high flow meter can result in potentially high losses in revenue. 2.2.3 Turbine Meters Turbine meters work by using water to rotate a turbine connected to a registering device. Turbine meters are designed for high flow applications and low head losses. Turbine meters are not very accurate at low or highly variable flow rates and are commonly available in sizes 2-inches and greater. The number of turbine meters used in most cities is typically small compared to other meter types; however a single turbine meter may measure 500 to 1,000 times more water volume than a residential meter per month, making them an important consideration. 2.3 Methodology The meter test methodology used for Phase Two of the water meter testing was similar to the methodology used for Phase One. Small meters up to 1-inch were tested in the City maintenance shop following AWWA standards. The large meter testing program went beyond the stated AWWA meter testing specifications. There are differences between meter testing conducted in the field versus testing meters in a controlled laboratory environment or established meter testing shop using volumetric tanks. Field conditions should be taken into consideration when testing meters in the field. Also the AWWA M-6 meter testing manual has no set "standards" for field testing, only to try to emulate as close as possible the suggested meter testing flow or to follow each meter manufacturer's suggested flow rates. Therefore, the Project Team found it imperative to adhere to a strict method of field testing while taking into consideration the AWWA meter performance standards. This methodology was designed to allow for a systematic diagnosis of the meter's performance based on several flow rates across that specific meter's size and type beyond the AWWA's three tests (minimum, intermediate, and maximum). Meters were tested across a range of flows in order to determine patterns of mechanical wear at various flow rates. The flow rates used are a combination of AWWA recommended flow rates (per M-6 manual of the AV4'WA) and meter manufacturer flow rates. All compound meters were tested at six flows rates, concentrating on the change over rate which is the most critical flow rate in a compound water meter. (AWWA states three tests, the change over rate being one of them. Reference AWWA M5 Manual, 4~' edition -Chapter 5) 1-1/2-inch and larger meters were tested by comparative methods using a certified test meter to test the water customer's meter within its normal operating range or by volumetric methods per AWWA M-6 Manual. Our comparative test meters were Sensus (formerly Rockwell) models that record total volume and current velocity for each of the 4 to 6 tests conducted. The test meters had "Electronic Registers" that were automatically reset to zero after each test. These comparative test meter units are themselves "Tested and Certified Accurate" at least once each year. Certificates of Accuracy were available on the service trucks if questions existed about how the meters were to be tested. There was a minimum of a two person field crew working on the meter testing program at all times, both in the field and during the shop testing of the smaller meters. All meters with a test port were HDR Englneering, Int. Dubuque Water A%leter Review and Testing tested in place. Meter installations where there were no test ports were documented. Each meter was analyzed as to the meter setting (i. e. installed piping connection configuration and service application) to determine if the meter could be tested in place without removal, and without undue inconvenience to the water customer. The Project Team observed each setting for an inlet valve, an outlet valve to be able to isolate the meter from use during testing, and a test port of correct size as well as position to attain enough flow velocity to test the meter across the range of flow rates for that specific meter. If a by-pass line was available, it was flushed prior to testing to insure no water service interruption for a critical customer such as a hospital. During each test, proper meter application and sizing were confirmed by visual inspection of the general area and observed meter readings to ensure the correct meter was in place and the setting is correct for the application (the meter setting is important because improper configurations can adversely affect meter accuracy). Some of the 1-1/2-inch and 2-inch displacement meters were able to be tested in place by using available test ports of existing backflow preventors. Here it was critical to achieve at least 14% or more of the lower operating range of that particular meter to be able to qualify as a valid meter test (per AWWA M-6 manual). Some of the 1-1/2-inch and 2-inch meters were tested at a sink using a calibrated small meter. Again, the flow tests used were at or over the lower 10% of the operating range of the meter. Shutdowns were limited when possible to minimize inconvenience for water customers. For Phase Two, testing of small meters (5/8-inch to 1-inch) included meters installed during or since 2442. Testing of large meters focused primarily on meters installed during or since 2442, although a small number of older meters were tested to provide additional information. Meters were randomly selected from this pool of candidates. A total of 152 meters were tested, ranging in size from 5/8- inch to 6-inches as follows: • 5/8-inch meters: 9 tested • 3/d-inch meters: 14 tested • 1-inch meters: 16 tested • 1-1/2-inch meters: 28 tested • 2-inch meters: 29 tested • 3-inch meters: 3 turbine meters and 32 compound meters were tested • 4-inch meters: 3 turbine meters and 15 compound meters were tested. • 6-inch meters: 1 compound meter and 2 fire line (6"x2") meters were tested The Project Team maintained an interactive role with the City Staff. The field staff met with assigned City Staff as needed. The Project Team worked with the City and water customers for all test scheduling and two (2) person teams were used to perform the work. Frequent communication was maintained with City Staff so problem meters and/or issues with water customers could be addressed in a timely manner. The Project Team conducted short interviews with staff about the "particulars" of the selected meter locations such as changes in the occupancy of the buildings, age of the meters, meter reading systems, etc. This provided a greater understanding of ho~~~ meters were functioning, allowing priorities to be assigned to particular segments of the work. City personnel were not required to assist field technicians except where there were issues with gaining entry due to security or other concerns. In some cases, City personnel helped the field crews and their help was genuinely appreciated. HDR Englneering, Int. Dubuque Water A%leter Review and Testing 3.0 Phase Two Meter Test Results 3.1 Phase Two Small Meter Test Results A total of 39 small meters were selected for testing ranging from 518-inch to 1-inch. 9 518-inch meters, l4 314-inch meters, and 161-inch meters were tested. Appendix 7.1 shows details of the test results for the small meters. The test results were subjected to two weighted averages, one was the 15%70%-15% as set by AWWA and the other weighted average was set at 5%90%5%. The percentages refer to the weighting given to the test results at low flow, intermediate flow and high flows. The highest weighting is given to intermediate flows since small meters usually do not operate at lo~v or high flows for extended lengths of time under normal usage. AWWA recommends 15%70%-15% as a weighted average to help figure usage patterns for residential meters. The 5%-90%-5%has been found to be more representative for some customers. The results using both weighted averages have been included with the results in Appendix 7.1. There was little variation between the two weighted averages, in both cases 15.4% of the meters failed. 'Ihe overall accuracy of the small meters at the 15%-70%15% average was 98.17% and 98.64% at 5%-90%-5%. Without detailed monitoring of the actual usage of each meter, it is impossible to know the actual weighted average of the meter. Given the similar results for both weighted averages, the AWWA recommended 15%-70%15%weighted average will be used for the purposes ofthis report and as was done for the Phase One report. Figure 3-1 shows the small meter test results.

DWugae WaterAleterReuiew ardTesting As expected, the percentage of meter failures was lower than the 33 percent observed in Phase One of the meter testing due to the lower age of the meters tested in Phase Ttvo. However, there were still some failures that were notable given the age of the meters. Ivleters tend to fail with increased age and are often covered by manufacturer warrantee for 5 years. With increasing age, meter failures and inaccuracy will increase fiu~ther. 3.2 Phase Two Large Meter Test Results Appendix 7.2 presents detailed summaries of the large meter testing results. Results of the Commercial/Industrial testing indicate there is loss of revenue occurring due to meters not performing to accepted standards. By the AWWWA standards, this is considered "Non-Revenue Water". Since water meters are the "cash registers" for the water system, the City of Dubuque is losing money with these meters as well. Figure 3-2 shows the large meter test results. Large meters make up a smaller portion of the meter population than the small meters, but convey much higher flow rates per meter and are potentially sources of significant revenue loss. A 4-inch meter will typically produce revenues of greater than $10,000 per year. Failure of a single large meter is equivalent in lost revenue to marry small meter failures. The failure rate of the meters tested for Phase Ttvo was lower than the Phase One meter tests. However, the failure rate was higher than expected given the low age of the meters. Of the 11 large meters that failed, 9 were less than five years old and 2 were eight years old. Table 3-1 shows the large meter tested accuracy by age.

The test results indicate that 14% of the 1-1/2-inch and 3.4% of the 2-inch meters failed testing. Relatively few new meters failed testing and meter repair and/or retrofit if cost effective may be an option for meters less than five years old instead of replacement. 3.2.3 Compound Meters Tested Compound meters are designed to operate over a wide range of flow rates. Typical consumption recorded by compounds should indicate 30-40% of usage on the low side, and 60-70% on the high side. 32 3-inch, 15 4-inch and 1 6-inch compound meters were tested. Based on the evaluations conducted by the Project Teain, the compound meters appear to be properly sized for the accounts that were visited. 6% of 3-inch, 13% of 4-inch and 0% of the 6-inch compound meters failed testing. Given the size and age of these meters, the failure rate is higher than expected among the 4-inch meters. 3.2.4 Turbine Meters Tested Three 3-inch, three 4-inch, and two 6-inch turbine meters were tested. These meters appear to be large revenue generators for the City. Most are installed in settings where water usage is fairly consistent. The Project Team tested for "start" flows of the turbine meters. This allowed the team to observe wear patterns for each meter. If the "start" flow was close to the minimum flow and the minimum flow was testing "slow", this indicated the probability of the meter registering "high" at the high flow. This is due to the mechanics of the meter. Relatively fe~v new meters failed testing and meter repair and/or retrofit if cost effective may be an option for meters less than five years old instead of replacement. 4.0 Summary of Phase One and Phase Two Results The results from the Phase One and Phase Two meter testing were combined to show a broader indication of meter performance. The meters tested for Phase One represent a wide cross section of meter sizes and ages, while the majority of the meters tested for Phase Two are less than five years old. The combined Phase One and Two results are therefore more heavily weighted to~~vards ne~~ver meters. HDR Englneering, Int. Dubuque Water A%leter Review and Testing Table 4-1 shows the combined results ofthe small meter tests ranging from 518-inch to 1-inch. A large number of 518-inch meters failed testing.

A single large meter conveys a much higher volume of water and associated revenue than many small meters the acceptable failure rate is less than for small meters. Replacement is recommended for the majority of the large meters. The 4-inch meters are of particular concern given the high failure rates for both old and new meters and volume of water conveyed. Some ofthe large meters known to be in acceptable condition would not necessarily need to be replaced, and could be retrofitted to work with the fixed radio system. HDR Engineering, Inc.

The analysis is based on meter size and consumption information provided by the City. Meter age was not considered for the revenue analysis since consumption information was not available based on meter age. Meter age can be considered in evaluating revenue in terms of availability of parts to repair meters. As meters age, accuracy tends to decrease leading to higher lost revenue.

A 9% increase is projected for fiscal year 2009 resulting in total revenue of $9,796,133. Analysis of the Phase One and Two meter testing showed that approximately 5.4% of total water consumption was not recorded due to meter inaccuracy, resulting in aprojected loss in revenue of approximately $530,000 for fiscal year 2009. The Phase Two meter tests focused on meters less than 5 years old. Given the large number of older meters in the City as shown in Table 5-1, it is likely that the lost revenue figure is somewhat higher than 5.4%. Based on the Phase One meter testing that randomly selected from a wider range of meter ages, approximately 6.9% or $676,000 in lost revenue was projected. The lost revenue figure will be compounded over time as existing meter accuracy worsens and water rates increase. HDR Engineering, Inc.

Based on the recommendations of the 2007 Meter Plan and System Evaluation and the results of the recently completed Water Meter Review and Testing, the following recommendations constitute the preferred strategic plan. • 112eter Reading Technology: Fixed Radio. After preliminary consideration of many meter technologies and detailed consideration of several potential meter options, the automatic meter reading (AMR) alternative of a fixed radio network was identified as the best option for implementation by the City. A fixed radio network allows remote reading of water meters, eliminating the need for meter reading labor for monthly billing readings. It is recommended that specific meter brands and options be re-evaluated once bids are solicited and costs are updated. • Meter Replacement, Repair or Upgrade. o Small meters (5/8-inch to 1-inch). It is re...,~~~~~~.,~~.:ed that all meters 5/8-inch to f - inch be replaced. Retrofit is not recommended for smaller meters due to the low marginal cost of meter replacement c.,~~~Y~ ed to the cost of meter retrofit. In addition, if all small meters are replaced, the system would be standardized around one type of meter with similar age that reduces inventory, and i~~~~,~., ves scheduling of future replacement. o Large meters (1-1/2-inch to 8-inch). It is recommended that all meters over five years old be replaced or repaired if cost effective and retrofitted to work with a fixed radio HDR Englneering, Int. Dubuque Water A%leter Review and Testing 13 system. It is recommended that meters less than five years old be evaluated for the potential for retrofit to work a fixed radio system. Deployment Time Period: Short (Contractor Installed). A short time period is recommended for deployment of new meters and meter reading technology. With contractor installation, City-wide meter replacement could occur within two years. The deployment period would likely increase to approximately ten years if the City were to deploy new equipment with existing City staff. Deployment Strategy: Opportunistic and Geographical. The recommended meter deployment approach is a combination of opportunistic and geographical strategies. Early opportunistic deployment will allow the City to first replace large meters with known accuracy problems and significant loss of revenue followed by geographical replacement «~hich is most efficient when working with Aquila for the meter system replacement. • Meter Maintenance/Management: o Before Meter Replacement: Contractor-Managed Meter Testing: This report details the results of the water meter review and testing program. The results of the testing helps the development of a cost-efTective replacement schedule for water meters and provides recommendations for the correction of the problems located. During Meter Replacement: City-Managed: It is recommended that the City establish a new meter testing protocol. A statistical sampling of one-half to one percent of all new meters would establish base-line data and confirm accuracy. This phase of meter management would be managed by the City, but the actual meter testing would conducted by the contractor as part of the meter replacement program. After Meter Replacement: City-Managed: The most important aspect of a water meter plan is the long-term management of the meters to ensure reliability and accuracy. It is recommended that the City develop a routine testing program to track trends in accuracy and maintenance. It is likely that a meter testing program would require some additional number of staff depending on the meter technology selected, which will influence the number of required field staff to an extent. Testing and maintenance is especially important for larger meters since relatively little labor can save significant loss in revenue. Regular testing of compound and turbine meters 3- inches and above and less frequent testing of smaller meters is recommended. 6.1 Implementation Considerations -Next Steps The following are key steps that will aid in implementation of the recommendations outlined above. These next steps will require considerable effort by the City and assistance by an experienced consultant is advised. Based on successful meter replacement projects, a draft consultant procurement/implementation project approach can be found in Appendix 7.3. • Site Visits: Visit other utilities to observe their experiences with water meter replacement programs and meter reading technology to better understand how these systems function, what is involved in a successful deployment, how the utilities are coping with integrating the new technology into day-to-day operations. Several regional utilities identified during the Water Meter System Evaluation have recently implemented new meter systems. • Meter System Procurement: Based on the Water Meter System Evaluation, Phase 1 & 2 Meter Testing and Review reports, site visits, current circumstances, operating environment, and staffing and resources, the City should define procurement issues and strategies. Once procurement requirements are defines, develop RFP/Bid specifications for water meter replacement. HDR Englneering, Int. Dubuque Water A%leter Review and Testing 14 • Solicit Responses from Qualified Vendors: Advertise RFP/Bid, along with conducting a mandatory pre-proposal meeting summarizing the City's objectives and requirements. • Vendor Evaluation and Selection: The procurement process involves making a defensible selection among qualified proposals using weighted multiple criteria to select a short list. • Re-evaluate Return on Investment: Once vendor RFP/Bids are received for water meter replacement, the information should be evaluated using the tools such as the cost model to evaluate the total life-cycle cost associated with each proposal to facilitate the City's final selection. • Contract Negotiation: Contracts for metering systems should be fair and equitable for all parties involved. Most of the performance requirements have been defined in the RFP/Bid specifications and the vendor's response. Contract negotiations usually focus on installation protocols and performance requirements. • Start-up Implementation and Administration: Proper project start-up is required for a timely and orderly installation of meters and meter-reading equipment, including adoption of new business processes to capture the benefits of any technology, and assure that the vendor and equipment are performing as stipulated in the contract. Once start-up is completed and accepted by the City, full implementation can begin. The 2007 Water Meter Plan and System Evaluation recommended installing a fixed radio network meter system as the lowest cost alternative. A fixed radio network allows remote reading of water meters, eliminating the need for labor intensive manual meter reading. From the 2007 Water Meter System Evaluation cost model, the 20 year present value (2009 dollars) capital cost of a fixed radio network water meter system will be approximately $6,850,000 and includes the cost of new water meters, radio equipment, computers and other hardware. Based on the combined Phase One and Phase Two current lost revenue and the estimated 2007 cost updated to 2009 dollars for a new fixed network meter system, the payback period would be approximately twelve years. The meters tested for Phase One represent a wide cross section of meter sizes and ages, while the majority of meters tested for Phase Two are less than five years old. The combined Phase One and Phase Two results are more heavily weighted towards meters less than five years old and may under-report the overall failure and accuracy rates since meter failures and inaccuracy tends to increase with meter age. Based on the Phase One meter testing results, the payback period would be approximately nine years. Table 6-1 shows the preliminary payback period for the fixed radio network meter replacement program. The lost revenue figure will be compounded over time as existing meter accuracy decreases and water rates increase. Table 6-1 for Fiscal The fixed radio system requires fewer employees for meter reading and results in lower operating and total costs than the existing system contracting with Aquila to read the meters. The fixed radio system alternative assumes City staff will be responsible for the radio network, billing and will continue to perform routine meter maintenance and replacement as is currently done. There is not expected to be any change in City staff levels from the current system to the fixed radio network system. However, the cost of contracting with Aquila will be saved. Currently, the annual cost for HDR Englneering, Int. Dubuque Water A%leter Review and Testing 15 Aquila is about $142,000 and is expected to increase approximately 3% per year due to anticipated inflation. A limited number of the City's newer meters in good working condition could be retrofitted to work with a fixed radio meter system. Retrofit is not recommended for smaller meters due to the low marginal cost of meter replacement compared to the cost of meter retrofit. In addition, if all small meters are replaced, the system would be standardized around one type of meter with similar age that reduces inventory, and improves scheduling of future replacement. Retrofit and repair could be beneficial for some large meters, although further evaluation will be required to determine if retrofitting is cost effective. In addition to direct cost savings, there are many operational and non-direct financial benefits of moving to a fixed radio network meter system compared to the existing meter system. Fixed radio network meters improve customer service and staff efficiency by allowing real-time meter reading. Water meter remote registers on the side of buildings will be removed and problems with meter accessibility and the need to enter a home or business for meter reading will be eliminated. The large amount of data that can be easily and remotely collected with a fixed radio network system will allow City staff to efficiently develop water system hydraulic models, track water consumption trends and plan for future water system requirements. Parts and repairs for some of the older existing water meters are becoming more difficult and new meters will allow for easier meter repair work. The high number of meters out of specification, annual lost revenue, and other benefits support implementing a meter change-out program. Based on a meter asset life of twenty years and a payback period of approximately ten years, there is a positive payback period and a meter replacement program is recommended. HDR Englneering, Int.

Dubuque Water A%leter Review and Testing 27 7.3 Typical Consultant Draft Procurementllmplementation Project Approach Project Approach Based on successful water meter replacement projects, the following proposed approach to assisting the City with procurement and initial implementation of an AMR system consists of three project phases: defining procurement requirements, performing procurement, and implementing of a start-up phase of AMR deployment before frill implementation proceeds. Amore detailed description of these tasks is provided below. Task 1-Define Procurement Requirements Objective: Reaffirm current and future metering needs of the City, which will in turn inform a procurement strategy that best meets the City's requirements. From the residential metering plan and drawing on our significant experience, consultant will identify current and anticipated future meter reading needs. Working with City staff, the consultant will establish system requirements, including installation, support and training, warranties and maintenance. New or modified business processes and operating procedures resulting from implementing an AMR system will also be considered. The consultant will develop a set of technical requirements that would be incorporated into a Request for Proposals/Bid for a water meter system. These include system component characteristics and performance requirements, meter interfaces, communication infrastructure, system controller hardware and software, installation procedures, and interfaces to City's other systems, along with the required demonstration process to be performed by the short-listed vendors. The consultant will compile a list of system technical and operational requirements and desirable features, as well as installation provisions, and review and revise these with the City's internal meter system procurement team in a work session. Task 2 -Procurement Process Management Objective: Provide an orderly procurement process that leads to the selection of the best AMR system for the City, including execution of a fair and equitable contract with the most qualified vendor or vendors. Approach: The following subtasks will comprise Task 2: • Task 2.1 Develop procurement document • Task 2.2 Construction/Installation Management • Task 2.3 Solicit responses from qualified vendors • Task 2.4 Evaluate and select the most qualified vendor or vendors • Task 2.5 Negotiate and execute a fair and equitable contract The consultant will support the City throughout the procurement process, it is important to have the City be actively involved with the entire evaluation and selection process. To assure this HDR Englneering, Int. Dubuque Water A%leter Review and Testing 28 involvement, the consultant will work with the City Management to establish a Selection Committee. It is suggested that the Selection Committee be limited to no more than seven people, including Account Services & Billing, Meter Maintenance, Meter Readers, and Customer Service staff. During the evaluation and selection period the consultant will act as an advisor to the City, coordinating and facilitating the selection process. The consultant will work with the Selection Committee to expedite the selection process and to confirm that the process follows the City procurement requirements. Task 2.1 -Develop Procurement Document The consultant, working with the Selection Committee, will prepare technical and bidding specifications based on the requirements identified in Task 1. The bid specifications will ensure that the City's goals and objectives are achieved while providing flexibility to vendors to present the most advantageous technology. The bidding document will present meter and meter reading requirements, as well as the procurement rules and guidelines. This will include procurement instructions, project description, minimum qualifications, technical and business requirements of the vendor (or vendors), evaluation criteria and selection methodology, proposal forms, and project schedule. The consultant will also work with the City's Purchasing and Legal Departments in preparing the proposal document so that it conforms to City requirements. The consultant will provide the "technical" requirements of the bid package, namely the technical specifications, suggested implementation timeline, and a draft contract. The City will be responsible to compile this information into a bid package that will include all the standard forms and bid requirements such as insurance requirements, affirmative action, equal employment opportunity, etc. Task 2.2 - ConstructionlInstallation Management Determine what assistance is required by the City during start-up implementation and management for full implementation. This scope of services should include at a minimum the following: • Control and Monitoring • Construction Schedules • Quality Management • Field Document Control • Construction Cost Control • Progress Payments • Safety/Security Programs • Training • Presentations and Reports • Monthly Invoices • Close-Out and Acceptance Services These services will be provided throughout the duration of the implementation process. Task 2.3 -Solicit Responses from Qualified Vendors The consultant will plan for and conduct aPre-proposal Conference. This will include preparing a summary of the City's objectives and requirements, scheduling and logistics for the Conference, and responding to any questions and data requests presented at the Conference. After the Conference, the consultant will continue to support the City in responding to questions and data requests. It is suggested that a master list of any requests be maintained in a database in order to ensure that all HDR Englneering, Int. Dubuque Water A%leter Review and Testing 29 responses are addressed and that all respondents have received the response. During the proposal phase the consultant will respond in writing to questions from prospective bidders. Task 2.4 -Evaluate and Select the Most Qualified Vendor(s) The consultant will assist with initial proposal review, creating a matrix that can be used as a checklist of submission requirements, and measurement of the respondent's ability to address meter and meter reading requirements. This matrix will allow the Selection Committee to rank the respondents in the major aspects of the proposal review, including submittal requirements, technical capability, knowledge of metering and AMR, water utility business acumen, and price. The consultant will prepare a technical memorandum summarizing the features and benefits included in the proposals, and recommend up to three firms that will be invited for vendor presentations. We will assist with respondent interviews for up to three selected vendors, including scheduling interviews, establishing interview guidelines, developing a presentation script, and moderating the process. The consultant will assist with reference checks of the highest ranked respondents. Reference checks should be thorough and comprehensive as it is through this process that the truly outstanding firms and systems are made apparent. The consultant will conduct due diligence on the selected vendors' financials, experience and qualifications. A list of questions will be developed and we will attempt to contact three current customers. If required, the consultant will an•ange for site visits with selected references to continn a respondent's capabilities through observation and open dialog with other companies and utilities using vendors' equipment. We will schedule and attend up to three site visits with the City staff of other utilities currently using the system. Finally, and perhaps most importantly, the consultant will assist with vendor demonstrations. For up to three short-listed vendors an AMR system demonstration will be performed in a selected area of the City. The results of the demonstration will be evaluated and be part of the final selection process. After the demonstrations, the consultant will prepare a technical memorandum to summarize the evaluation and selection process. While this summary will be drafted by the consultant, it is the Selection Committee that will rank the proposals and recommend a preferred vendor. Task 2.5 -Negotiate and Execute a Fair and Equitable Contract The consultant will provide advice and guidance to the City during its negotiations with the lead respondent. We will expedite negotiations in support of the implementation start date by developing a negotiation schedule, assisting with developing a draft contract, and acting as a liaison between the lead respondent and City. An important element of contract negotiation is fairness and equity. The consultant will work to protect the interest of the City, but will advise Dubuque when certain conditions and restrictions prove too onerous. A contract that fairly protects the interests of both parties provides the best environment for a lasting and beneficial relationship. The consultant will work with the parties to create a detailed statement of work (DSOW), which will be attached to the contract and serve as the "manual of practice" for the parties during the project deployment/implementation. The DSOW covers meters and meter reading system installation and HDR Englneering, Int. Dubuque Water A%leter Review and Testing 30 testing procedures, project control and invoicing, communications and documentation between the vendor and the utility, etc. Upon successful contract negotiation, the consultant will assist the City in a presentation to City Council should one be required to gain final approval. Task 3 -Start-up Implementation and Administration Objective: To provide project start-up support for a timely and orderly installation of meters and meter-reading equipment, including adoption of new business processes to capture the benefits of AMR, and assure that the vendor and equipment are performing as stipulated in the contract. Once start-up is completed and accepted by the City full implementation can begin. Approach: The following subtasks will comprise Task 3: • Task 3.1 Manage initial program implementation • Task 3.2 Monitor vendor and equipment performance Task 3.1 -Manage Initial Program Implementation The consultant will evaluate the vendor's implementation schedule, monitor implementation progress, and present regular reports to City management. Our overriding objective will be to support the City and vendor so that the AMR operational start date will be achieved as planned. Communication is very important during implementation. Both internal and external constituents need to be apprised of the implementation plan, and potential problems that could occur during implementation and startup. It is also important that the City have in place a response program in the event that the implementation does not proceed according to plan. The consultant will provide reports to the City Management on a regular basis identifying successes, as well as deficiencies. In its operational startup support role, the consultant will work to promote the new AMR, and minimize any negative impact that results from its implementation. Once start-up implementation has been accepted by the City, full implementation will begin with the selected contract manager assuming full implementation responsibilities. Task 3.2 -Monitor Vendor and Equipment Performance The consultant will provide project administration support to the City through the start-up implementation project. This will include confirmation of the vendor's compliance to the contract, and assessing performance of the AMR system to verify it meets specified requirements. The consultant will also help develop auditing tools and reports that will allow the City to track the vendor and equipment performance on an on-going basis. Also included are the necessary project supervision, direction and coordination with the City's management and staff. We will review correspondence, project activities, billings, conduct reviews, prepare status reports, and conduct discussions with the City's staff as necessary. HDR Englneering, Int. Dubuque Water A%leter Review and Testing 31 Task 4 - On-going Implementation Assistance The consultant will be pleased to provide, as an optional supplemental service, any additional ongoing assistance that maybe requested by the City. We have extensive experience with training, inspection of vendor installations, and procurement of support components. HDR Englneering, Int.
