August 29, 2006 City of Atlantic Beach Attn: Donna Kaluzniak 1200 Sandpiper Lane Atlantic Beach, FL 32233 Dear Ms. Kaluzniak: Hughes Supply, Inc.,U tility Services Group (Hughes) i s pleased to submit the enclosed Final Report on leak detection services recently completed. A total of approximately 11.16 miles (estimated by Field Technician) have been surveyed including all intersecting lines. Approximately 40.84 hours of fieldwork were spent during this project. A total of eight (8) le aks were pinpointed. Additionally, o ne 1( )c o nsumer side leaks were noted, a s detailed in this Final Report. The water loss due to leakage was estimated to be, excluding undefined and consumer side leaks, approximately 24,480 GPD. Details of this information are enclosed. Please note that leakage that was detected and pinpointed may be larger or smaller than estimated. Estimates are based on several variables including type and size of pipe, pressure and interpretation of correlation filter results. As you review this Final Report, please pay close attention to the Field Technician's remarks and field observations in the Project Observation section of this report. These may assist you in determining the best course of action regarding specific leaks. We strongly suggest you contact us prior to excavating any leak that we have labeled with "CAUTION" for further explanation. The leak detection survey is productive since we pinpointed leakage that, when repaired, can reduce your water loss, saving the City of Atlantic Beach dollars now and in the future. We appreciate your confidence in Hughes. If you have any questions, call us at (800) 621 -9292 or (206) 725 -3441. 7relY Rob Mes ton Manager EXECUTIVE SUMMARY Summary of Survey and Pinpointing Report Client: City of Atlantic Beach, FL Date: 0207/0268/Period Covered: July 24, 2006 through July 28, 2006 TOTAL ANNUAL WATER LOSS General Area Covered: Southeast and West formula: leak.GPM x min/hour x hours/day x days/year) 1 2800,.9035, GALLONS SURVEY DATA Distance Surveyed : 58900.000 feet , 11.160 miles Time Spent Surveying : 23.92 hours I Points Surveyed Access Points Requiring further investigation Hydrants 82 points that are returned to for pinpointing or elimination) Valves 90 Leak sounds on: Valves 0 Services 1310 Hydrants 0 Other 0 Services 13 Total 1482 Other 0 Total 13 PINPOINTING DATA f LEAK TYPE NUMBER TIME SPENT TOTAL, TOTAL, LARGEST, LARGEST, SMALLEST, SMALLEST, AVERAGE of LEAKS PINPOINT-GALLONS GALLONS PER GALLONS GALLONS PER GALLONS GALLONS PER LEAK SIZE ING (hours) PER MIN DAY PER MIN DAY PER MIN DAY GPM MAIN LINE VALVE 6 1.00 1.7 2520.0 0.5 720.0 0.25 360.00 0.29 HYDRANT METER 1 0.17 0.2 360.0 0.2 360.0 0.25 360.00 0.25 CURB STOP SERVICE LINE SERVICE CONN 1 1.25 15.0 21600.0 15.0 21600.0 15.00 21600.00 15.00 OTHER UNDEFINED TOTALS 8 2.42 17.00 24480 n. a. n. a n. a n. a 2.130 Sites Investigated for Pinpointing 13 Other Time Spent on Project (includes pinpointing false leak sounds) 14.50 hrs. FL125 Job# i PROJECT OBSERVATIONS PROJECT OBSERVATIONS Water Distribution Lines) GENERAL On July 28, 2006 Hughes completed a 5 d-ay leak detection survey on the southeast and west sections of the water distribution system for the Atlantic Beach, FL. The notes below have been generated by our Field Technician and have been included as part of the Executive Summary. SPECIFICS The survey was broken down in two different phases: 1. Survey Phase — sounding of appurtenances and recording leak type noises that were detected. 2. Pinpointing Phase — pinpointing noises that were detected during the Survey Phase. 1. Survey Phase Information The entire area surveyed consisted of PVC pipe material and as such was conducted by making contact with all available appurtenances. Appurtenances were found in mostly good condition. Any anomalies have been noted in the Observation Section of the Area Survey Reports. 2. Pinpointing Phase Information As a result of our survey, we were able to locate and pinpoint nine (9) leaks, one (1) of which is a suspected consumer side leak. Leak specific information follows: Leak Report #8 —Th is large leak was pinpoint to a service connection. The leak was repaired. Consumer Side Leak Report #A —Th is suspected consumer side leak will require additional investigation by the customer. CONCLUSION We were able to locate and pinpoint leakage, indicating that leaks do not readily surface in the system. Make note of any discrepancies in our estimates as they may have a substantial effect on non -revenue water calculations. Also, if you have any questions on any noted Leak Reports, please contact our office for further details and specific action. We look forward to working with the City of Atlantic Beach on future conservation projects.

We utilized the latest in leak detection technology available. We employed extremely sensitive sound amplification instruments for the survey and a computer based correlator for leak pinpointing whenever possible. Our field technician, Eric Kelsay, used and appreciated the information provided to expedite and provide an accurate survey. The survey was accomplished in the following steps: 1. The first step in our survey was to review the distribution maps of our City of Atlantic Beach system for familiarization of the pipe network and available appurtenances valves, services, hydrants, etc.)to be used as contact points. 2. Hughes then conducted a comprehensive survey by making physical contact with all available appurtenances (valves, hydrants, and services). Hughes used a sonic leak detection sound amplification instrument designed for this purpose. 3. When normal contact points were not available or could not be created within a reasonable distance, as described in Paragraph D, we made an attempt to use a sonic ground listening instrument, making physical ground contact at intervals no greater than 6 feet directly over the pipe. If conditions did not allow this procedure, our Field Technician advised City of Atlantic Beach at time of project and detailed in the Final Report. If excessive ambient noise precluded the effectiveness of the ground listening device in an area during daytime hours, we scheduled this portion of the survey for nighttime hours. We pre-approved these situations with City of Atlantic Beach. (Ground listening devices are employed when ground cover is pavement, cement, or a similar had surface.) Direct contact to the main line at intervals outlined in Preparation for Service result in the most thorough survey possible. 4. When ground cover was not a hard surface, probe rods were used at 6 feet intervals when normal contact points are not available. A sound amplification instrument with 3VG or greater (volts per "G"t)ra n sducer was used on probe rods. Probe rods were driven into the ground a minimum of 6 inches, directly over the pipe, when ground conditions allow. 5. A detailed report of decibel levels at suspected leak sound locations and observations were compiled during the survey for reinvestigation and possible pinpointing at a later time. This reinvestigation was to increase the speed of the survey and it eliminated correlating on most false leak sounds (i.e. Service draw). 6. All indications, of leaks found during survey, were verified a second time, after which the leakage was pinpointed with a computer based leak sound correlator when possible. Pinpointing leak locations through interpretation of sound intensity, either by ear, decibel metering, or other like methods, was not used when contact points are available for use with the correlator. 7. The equipment utilized does not normally require valves to be operated during surveying and pinpointing. However, on occasion, services or valves were operated to eliminate service draw noises or to change velocity noise. 8. The correlator equipment used had the capability to prompt the operator to input the variables when different pipe sizes and /or pipe material were encountered in the same span to be investigated. This is necessary to insure accuracy of results based on the automatic computation of the correct leak sound velocity in leak pinpointing operations. Our correlators have the capability of correlating up to seven various pipe sizes and types at one time in a given space. To insure effective performance in all field environments encountered in the distribution system (i.e. traffic noise, draw, pump opperation, industrial noise, etc.), c o rrelator equipment prroovviiddeess 12 multir-ang9ea HHiig9h and Low Pass filters. 9. We provided a copy of leak reports, when pinpointed, which included leak locations and estimated GPM loss. These leak reports included a leak priority classification. These classifications are as follows: Class I. Any leak which is hazardous in terms of potential undermining, possibly resulting in surface collapse, encroachment and /or damage to nearby utilities, commercial or private properties or leaks severe enough to warrant immediate repair. Class II. All leaks that display water losses significant enough to be monitored on a regular repair schedule. Class III. Relatively small leaks that should be repaired as workload permits. 10. Whenever any leak detected by Hughes was repaired prior to completion of the field work, Hughes resurveyed that section of the system, to be sure no very quiet leaks were missed due to an over powering noisy leak sound. Hughes furnished a trained field technician, leak detection instruments, equipment and tools to complete the survey and leak pinpointing as outlined in our proposal. After reviewing all records relating to this project we feel certain that we have performed our best effort to pinpoint all existing leaks within the areas of the water system we surveyed. We strongly recommend that City of Atlantic Beach maintain some type of on -going leak detection program. Only through a continuing leak detection program can your City of Atlantic Beach expect to keep the incidence of leakage under control. Such a program will definitely prevent future leak losses from becoming a major contributor to the system's unaccounted for water losses. In our effort to provide the most comprehensive service possible, we requested in advance to have your personnel prepare the areas to be surveyed by taking measures to ensure that the majority of main line valves were accessible. Efforts were made in this advance preparation. This was greatly appreciated.

LEAK SURVEY CONCLUSION Our thanks to Donna Kaluzniak and all persons involved with this project for their assistance in gathering all the necessary paperwork and personnel to create, with Hughes, a mutually beneficial leak detection project. With this survey you have demonstrated concern for prudent water utilization and conservation. Capitalizing on the most advanced leak detection technology available today, Hughes has successfully completed this Leak Detection Survey. The contents of this Final Report provide the City of Atlantic Beach with a permanent record of the activities performed to complete a Leak Survey along with the results achieved. An important characteristic of this Leak Report is that the facts contained herein can be used in formulating a database for decision making regarding: the need for possible future meter programs, rehabilitation and pipe line replacement and /or the investigation of new water sources, etc. These types of decisions, regarding your utilization of water, now can be predicated more on facts rather than supposition or conjecture. Prompt repair of any leaks reported provide an immediate benefit to the City of Atlantic Beach, which includes recovery of most water revenue and water conservation, etc. Having achieved these results, we recommend that you continue to set up the infrastructure necessary to continue investigating leakage in the water distribution system. Implementation of any on -going leak survey program will ensure that leak losses are kept to a minimum, and the added enhancement of saving costs due to emergency call outs. Hughes Supply, Inc., Utility Services Group is proud to have served the City of Atlantic Beach in this way and we wish to thank you for your substantial assistance and cooperation in this project. If you or your staff has any questions regarding this Final Report, please feel free to call us at (800) 621 -9292 or (206) 725 -3441.

A total of approximately 19.19 miles have been surveyed including all intersecting lines. Approximately 40 hours were spent on this project. A total of ten 1( 0) le aks were pinpointed, as detailed in this Final Report. The water loss due to leakage was estimated to be approximately 20,520 GPD. Details of this information are enclosed. Please note that leakage that was detected and pinpointed may be larger or smaller than estimated. Estimates are based on several variables including type and size of pipe, pressure and interpretation of correlation filter results. As you review this Final Report, please pay close attention to the Field Technician's remarks and field observations in the Project Observation section of this report. These may assist you in determining the best course of action regarding specific leaks. We strongly suggest you contact us prior to excavating any leak that we have labeled with "CAUTION" for further explanation. Page one of our Leak Report section contains a legend of information detailed in the leak diagram. We hope you will also find the Leak Report Summary and graph of leakage helpful in your water conservation efforts. The leak detection survey is productive since we pinpointed leakage that, when repaired, can reduce your water loss, saving the City of Atlantic Beach dollars now and in the future. We appreciate your confidence in Hughes. If you have any questions, call us at (800) 621 -9292 or (206) 725 -3441.

PROJECT OBSERVATIONS Project Observations Water Distribution Lines) GENERAL From May 03, 2004 through May 07, 2004 Hughes Utility Services completed a leak detection survey on various sections of the water distribution system for City of Atlantic Beach, FL. The notes below have been generated by our Field Technician and have been included as part of the Executive Summary. SPECIFICS The survey was broken down in two different phases: 1. Survey Phase — sounding of appurtenances and recording leak type noises that were detected. 2. Pinpointing Phase — pinpointing noises that were detected during the Survey Phase. 1. Survey Phase Information Excellent preparedness combined with excellent field assistance helped to greatly expedite the survey. The older lines throughout the distribution system were targeted for the survey. The majority of pipe type was PVC with limited AC and Iron also checked. All PVC and AC lines surveyed were checked point t-o-p oint, making contact with all available appurtenances. Appurtenances were found in mostly good condition. Any anomalies have been noted in the Observation Section of the Area Survey Reports. 2. Pinpointing Phase Information As a result of our survey, we were able to locate and pinpoint ten (10) leaks. Leak specific information follows (note not all leaks have been detailed below. Refer to the Leak Reports for further details). Leak Report #3 —Thi s leak is most likely near the meter box although the exact location could not be determined. Use caution. Leak Report #5 —W ater in the box indicates the leak is most likely a coupling or meter nut. Further investigation may be required by pumping out box and investigating. Leak Report #6 —W ater in the box indicates the leak is most likely a coupling or meter nut. Further investigation may be required by pumping out box and investigating. Leak Report #8 -Water in the box indicates the leak is most likely a coupling or meter nut. Further investigation may be required by pumping out box and investigating. Leak Report #9 —Un able to pinpoint exact leak location. Noise was detected over the entire length of the service line with the portable unit. Since water is entering the meter box, we suggest you start digging there, moving towards the service connection. Use caution. CONCLUSION We were able to locate and pinpoint leakage, indicating that leaks do not readily surface in the system. Make note of any discrepancies in our estimates as they may have a substantial effect on non -revenue water calculations. Also, if you have any questions on any noted Leak Reports, please contact our office for further details and specific action. I would like to thank Virgil Rosario for his field assistance, which proved invaluable. We look forward to working with the City of Atlantic Beach on future conservation projects.

We utilized the latest in leak detection technology available. We employed extremely sensitive sound amplification instruments for the survey and a computer based correlator for leak pinpointing whenever possible. Our field technician, Jeff Ruppel, used and appreciated the information provided by Virgil Rosario to expedite and provide an accurate survey. The survey was accomplished in the following steps: 1. The first step in our survey was to review the distribution maps of our City of Atlantic Beach system for familiarization of the pipe network and available appurtenances valves, services, hydrants, etc.)to be used as contact points. 2. Hughes then conducted a comprehensive survey by making physical contact with all available appurtenances (valves, hydrants, and services). Hughes used a sonic leak detection sound amplification instrument designed for this purpose. 3. When normal contact points were not available or could not be created within a reasonable distance, as described in Paragraph D, we made an attempt to use a sonic ground listening instrument, making physical ground contact at intervals no greater than 6 feet directly over the pipe. If conditions did not allow this procedure, our Field Technician advised City of Atlantic Beach at time of project and detailed in the Final Report. If excessive ambient noise precluded the effectiveness of the ground listening device in an area during daytime hours, we scheduled this portion of the survey for nighttime hours. We pre-a pproved these situations with City of Atlantic Beach. G( round listening devices are employed when ground cover is pavement, cement, or a similar had surface.) Direct contact to the main line at intervals outlined in Preparation for Service result in the most thorough survey possible. 4. When ground cover was not a hard surface, probe rods were used at 6 feet intervals when normal contact points are not available. A sound amplification instrument with 3VG or greater (volts per "G ") transducer was used on probe rods. Probe rods were driven into the ground a minimum of 6 inches, directly over the pipe, when ground conditions allow. 5. A detailed report of decibel levels at suspected leak sound locations and observations were compiled during the survey for reinvestigation and possible pinpointing at a later time. This reinvestigation was to increase the speed of the survey and it eliminated correlating on most false leak sounds (i.e. Service draw). 6. All indications, of leaks found during survey, were verified a second time, after which the leakage was pinpointed with a computer based leak sound correlator when possible. Pinpointing leak locations through interpretation of sound intensity, either by ear, decibel metering, or other like methods, was not used when contact points are available for use with the correlator. 7. The equipment utilized does not normally require valves to be operated during surveying and pinpointing. However, on occasion, services or valves were operated to eliminate service draw noises or to change velocity noise. 8. The correlator equipment used had the capability to prompt the operator to input the variables when different pipe sizes and /or pipe material were encountered in the same span to be investigated. This is necessary to insure accuracy of results based on the automatic computation of the correct leak sound velocity in leak pinpointing operations. Our correlators have the capability of correlating up to seven various pipe sizes and types at one time in a given space. To insure effective performance in all field environments encountered in the distribution system (i.e. traffic noise, draw, pump operation, industrial noise, etc.)th, e correlator equipment provides 12 multi r-ange High and Low Pass filters. 9. We provided a copy of leak reports, when pinpointed, which included leak locations and estimated GPM loss. These leak reports included a leak priority classification. These classifications are as follows: Class I. Any leak which is hazardous in terms of potential undermining, possibly resulting in surface collapse, encroachment and /or damage to nearby utilities, commercial or private properties or leaks severe enough to warrant immediate repair. Class II. All leaks that display water losses significant enough to be monitored on a regular repair schedule. Class III. Relatively small leaks that should be repaired as workload permits. 10. Whenever any leak detected by Hughes was repaired prior to completion of the field work, Hughes resurveyed that section of the system, to be sure no very quiet leaks were missed due to an over powering noisy leak sound. Hughes, Utility Services Group furnished a trained field technician, leak detection instruments, equipment and tools to complete the survey and leak pinpointing as outlined in our proposal. After reviewing all records relating to this project we feel certain that we have performed our best effort to pinpoint all existing leaks within the areas of the water system we surveyed. We strongly recommend that City of Atlantic Beach maintain some type of on -going leak detection program. Only through a continuing leak detection program can your City of Atlantic Beach expect to keep the incidence of leakage under control. Such a program will definitely prevent future leak losses from becoming a major contributor to the system's unaccounted for water losses. In our effort to provide the most comprehensive service possible, we requested in advance to have your personnel prepare the areas to be surveyed by taking measures to ensure that the majority of main line valves were accessible. Efforts were made in this advance preparation. This was greatly appreciated.

The following pages outline exactly how those two phases progressed and the results of each. Any leaks pinpointed will be detailed in the attached Leak Reports. PROJECT OBSERVATIONS PROJECT OBSERVATIONS Water Distribution Lines) GENERAL On March 11, 2011 USA completed a 5 -day leak detection survey on various sections of the water distribution system for the City of Atlantic Beach, FL. The notes below have been generated by our Field Technician and have been included as part of the Executive Summary. SPECIFICS The survey was broken down in two different phases: 1. Survey Phase — sounding of appurtenances and recording leak type noises that were detected. 2. Pinpointinq Phase — pinpointing noises that were detected during the Survey Phase. 1. Survey Phase Information Excellent preparedness combined with good sound travel and access helped to greatly expedite the survey. The survey this year, focused on the following areas: Beach to Seminole Ocean Walk Atlantic to Ocean Breeze Levy to Dutton Island Mayport to Paradise The lines along Fleet Landing had very limited access. Because they are PVC, it is very possible that a quieter leak noise could have easily gone undetected along this line. It should be noted that we discovered several valve and meter boxes that were damaged or missing altogether. Whenever these are discovered, they should be replaced to reduce or eliminate possible liability issues. We also discovered about 20%of the valve boxes that were compacted with debris and /or could not be accessed using a probe rod. 2. Pinpointing Phase Information As result of our survey, we were able to locate and pinpoint eighteen (18) le aks. More information follows on specific leaks. For additional information and a drawing on each leak, please refer to the Leak Report section of this Final Report: Leak Report #18 We suspect this leak is at or near the meter. Correlations were week. Although we confirmed the leak is not on the customer side, we were not able to pinpoint the exact location. We suggest you expose the meter and fillings and if no leak is found, excavate towards the main. CONCLUSION Overall, the portions of the system surveyed appear to be in good condition. However, leakage was detected and identified indicating that not all Teaks surface. Make note of our estimates when repairing the Teaks as this may have a significant impact when calculating water Toss figures. For future surveys we suggest that you have the valves boxes cleaned before we arrive. This will allow for a more efficient and comprehensive survey to be complete. We look forward to working with City of Atlantic Beach on future conservation projects. Compiled from field notes respectfully submitted by: Jeff Benjamin Field Technician SURVEY PHASE REVIEW SURVEY PHASE REVIEW Water Distribution Lines) The first step in our survey was to review the distribution maps of the system for familiarization of the pipe network and available appurtenances to be used for contact points. Since the system is comprised of mostly PVC, we then conducted a comprehensive survey by making physical contact with all available appurtenances (valves, hydrants, services, etc.). USA used a sonic leak detection amplification instrument designed for this purpose. Appurtenances Surveyed Hydrant 170 Valves 199 Services 1,211 Other 0 Total 1,580 When normal contact points were not available or could not be created within a reasonable distance, we made an attempt to use a sonic ground listening instrument to make physical ground contact at intervals no greater than 6 feet directly over the pipe. If conditions did not allow this procedure our Field Technician advised you at time of project and notes of such are included in the Project Observations. Ground listening devices are employed when ground cover is pavement, cement or similar hard surface. When ground cover was not a hard surface and normal contact points were not available, we made an attempt to use probe rods or a specially designed sounding plate at 6 f-oot intervals. A sound amplification instrument with 3VG or greater transducer was employed in conjunction with this equipment, directly over the pipe. If conditions did not allow this procedure our Field Technician advised you at time of project and was detailed in the Project Observations section of this Final Report. Direct contact to the main line at intervals outlined in Preparation for Service resulted in the most thorough survey. A detailed report of decibel levels at suspected leak sound locations and observations were compiled during the survey for reinvestigation and possible pinpointing at a later time. This reinvestigation increased the speed of the survey and eliminated correlating on most false leak sounds.

Pinpointing leak locations through interpretation of sound intensity, either by ear, decibel metering or other like methods was not used when contact points were available for use with the correlator. However, ground listening devises were used as a quick double check on pinpointed leaks. The equipment used did not normally require valves to be operated during surveying and pinpointing. However, on occasion, services or valves were operated to eliminate service draw noises or to change velocity noise. The correlator equipment used had the capability to prompt the operator to input the variables when different pipe sizes and /or pipe material were encountered in the same span to be investigated. This is necessary to insure accuracy of results based on the automatic computation of the correct leak sound velocity in leak pinpointing operations. Our correlators have the capability of correlating up to seven various pipe sizes and types at one time in a given space. To insure effective performance in all field environments encountered in the distribution system (i.e. traffic noise, draw, pump operation, industrial noise, etc.)th,e correlator equipment provides 16 auto filter options and /or infinite manual filter options. We provided a copy of leak reports, when pinpointed, which included leak locations and estimated GPM loss.

Please note that leakage that was detected and pinpointed may be larger or smaller than estimated. Estimates are based on several variables including type and size of pipe, pressure and interpretation of correlation filter results.

With this survey you have demonstrated concern for prudent water utilization and conservation. Capitalizing on the most advanced leak detection technology available today, USA has successfully completed this Leak Detection Survey. The contents of this Final Report provide the City of Atlantic Beach with a permanent record of the activities performed to complete a Leak Survey along with the results achieved. An important characteristic of this Leak Report is that the facts contained herein can be used in formulating a database for decision making regarding: the need for possible future meter programs, rehabilitation and pipe line replacement and /or the investigation of new water sources, etc. These types of decisions, regarding your utilization of water, now can be predicated more on facts rather than supposition or conjecture. Prompt repair of any leaks reported provide an immediate benefit to the City of Atlantic Beach, which includes recovery of most water revenue and water conservation, etc. Having achieved these results, we recommend that you continue to set up the infrastructure necessary to continue investigating leakage in the water distribution system. Implementation of any on -going leak survey program will ensure that leak losses are kept to a minimum, and the added enhancement of saving costs due to emergency call outs. Utility Services Associates, LLC, is proud to have served the City of Atlantic Beach in this way and we wish to thank you for your substantial assistance and cooperation in this project. If you or your staff has any questions regarding this Final Report, please feel free to call us at 877) 585 -5325 or (206) 244 -0370.

A total of approximately 15.23 miles (estimated by Field Technician) have been surveyed including all intersecting lines. Approximately 38.75 hours of fieldwork were spent during this project. A total of sixteen (16) Teaks were pinpointed. Additionally, two (2)c o nsumer side leaks were noted, as detailed in this Final Report. The water loss due to leakage was estimated to be, excluding consumer side leaks, approximately 32,400 GPD. Details of this information are enclosed. Please note that leakage that was detected and pinpointed may be larger or smaller than estimated. Estimates are based on several variables including type and size of pipe, pressure and interpretation of correlation filter results. As you review this Final Report, please pay close attention to the Field Technician'sremarks and field observations in the Project Observation section of this report. These may assist you in determining the best course of action regarding specific leaks. We strongly suggest you contact us prior to excavating any leak that we have labeled with "CAUTION" for further explanation. The leak detection survey is productive since we pinpointed leakage that, when repaired, can reduce your water loss, saving the City of Atlantic Beach dollars now and in the future. We appreciate your confidence in Hughes. If you have any questions, call us at (800) 621 -9292 or (206) 725 -3441.

PROJECT OBSERVATIONS PROJECT OBSERVATIONS Water Distribution Lines) GENERAL On January 14, 2005 Hughes completed a leak detection survey on the Northeast sections of the water distribution system for City of Atlantic Beach, FL. The notes below have been generated by our Field Technician and have been included as part of the Executive Summary. SPECIFICS The survey was broken down in two different phases: 1. Survey Phase — sounding of appurtenances and recording leak type noises that were detected. 2. Pinpointing Phase — pinpointing noises that were detected during the Survey Phase. 1. Survey Phase Information Excellent preparedness combined with excellent field assistance helped to greatly expedite the survey. A point -to -point survey was completed. Appurtenances were found in mostly good condition. Any anomalies have been noted in the Observation Section of the Area Survey Reports. 2. Pinpointing Phase Information As a result of our survey, we were able to locate and pinpoint sixteen (16) Teaks. In addition, we have noted two (2) su spected consumer side Teaks. Leak specific information follows. N (ote not all leaks have been detailed below. Refer to the Leak Reports for further details). Leak Report #2 —Th is leak is most likely near the meter box although the exact location could not be determined. Use caution. Leak Report #7 —Th is visible leak is so small that it was not estimated. Leak Report #12 —Th is is a fairly good size main leak on 2"g alvanized line. The leak is surfacing in the ditch line at the point indicated on the drawing. Consumer Side Leak Reports # A & B — These suspected leaks will require further investigation. CONCLUSION We were able to locate and pinpoint leakage, indicating that leaks do not readily surface in the system. However, overall, the lines inspected appear to be in good condition with many of the leaks being relatively small. Most should be easily repairable based on their locations (many were in meter box). Make note of any discrepancies in our estimates as they may have a substantial effect on non -revenue water calculations. Also, if ou have anyy questions on any noted Leak Reports, please contact our office for further details and specific action. would like to thank Barrion Hill for his field assistance, which proved invaluable. We look forward to working with the City of Atlantic Beach on future conservation projects.

We utilized the latest in leak detection technology available. We employed extremely sensitive sound amplification instruments for the survey and a computer based correlator for leak pinpointing whenever possible. Our field technician, Jeff Ruppel, used and appreciated the information provided by Barrion Hill to expedite and provide an accurate survey. The survey was accomplished in the following steps: 1. The first step in our survey was to review the distribution maps of our City of Atlantic Beach system for familiarization of the pipe network and available appurtenances valves, services, hydrants, etc.t)o be used as contact points. 2. Hughes then conducted a comprehensive survey by making physical contact with all available appurtenances ( valves, hydrants, and services). Hughes used a sonic leak detection sound amplification instrument designed for this purpose. 3. When normal contact points were not available or could not be created within a reasonable distance, as described in Paragraph D, we made an attempt to use a sonic ground listening instrument, making physical ground contact at intervals no greater than 6 feet directly over the pipe. If conditions did not allow this procedure, our Field Technician advised City of Atlantic Beach at time of project and detailed in the Final Report. If excessive ambient noise precluded the effectiveness of the ground listening device in an area during daytime hours, we scheduled this portion of the survey for nighttime hours. We pre-approved these situations with City of Atlantic Beach. Ground listening devices are employed when ground cover is pavement, cement, or a similar had surface.) Direct contact to the main line at intervals outlined in Preparation for Service result in the most thorough survey possible. 4. When ground cover was not a hard surface, probe rods were used at 6 feet intervals when normal contact points are not available. A sound amplification instrument with 3VG or greater (volts per "G ") transducer was used on probe rods. Probe rods were driven into the ground a minimum of 6 inches, directly over the pipe, when ground conditions allow. 5. A detailed report of decibel levels at suspected leak sound locations and observations were compiled during the survey for reinvestigation and possible pinpointing at a later time. This reinvestigation was to increase the speed of the survey and it eliminated correlating on most false leak sounds (i.e. Service draw). 6. All indications, of leaks found during survey, were verified a second time, after which the leakage was pinpointed with a computer based leak sound correlator when possible. Pinpointing leak locations through interpretation of sound intensity, either by ear, decibel metering, or other like methods, was not used when contact points are available for use with the correlator. 7. The equipment utilized does not normally require valves to be operated during surveying and pinpointing. However, on occasion, services or valves were operated to eliminate service draw noises or to change velocity noise. 8. The correlator equipment used had the capability to prompt the operator to input the variables when different pipe sizes and /or pipe material were encountered in the same span to be investigated. This is necessary to insure accuracy of results based on the automatic computation of the correct leak sound velocity in leak pinpointing operations. Our correlators have the capability of correlating up to seven various pipe sizes and types at one time in a given space. To insure effective performance in all field environments encountered in the distribution system (i.e. traffic noise, draw, pump operation, industrial noise, etc.)th, e correlator equipment provides 12 multi -range High and Low Pass filters. 9. We provided a copy of leak reports, when pinpointed, which included leak locations and estimated GPM loss. These leak reports included a leak priority classification. These classifications are as follows: Class I. Any leak which is hazardous in terms of potential undermining, possibly resulting in surface collapse, encroachment and /or damage to nearby utilities, commercial or private properties or Teaks severe enough to warrant immediate repair. Class II. All leaks that display water losses significant enough to be monitored on a regular repair schedule. Class III. Relatively small leaks that should be repaired as workload permits. 10. Whenever any leak detected by Hughes was repaired prior to completion of the field work, Hughes resurveyed that section of the system, to be sure no very quiet leaks were missed due to an over powering noisy leak sound. Hughes furnished a trained field technician, leak detection instruments, equipment and tools to complete the survey and leak pinpointing as outlined in our proposal. After reviewing all records relating to this project we feel certain that we have performed our best effort to pinpoint all existing leaks within the areas of the water system we surveyed. We strongly recommend that City of Atlantic Beach maintain some type of on -going leak detection program. Only through a continuing leak detection program can your City of Atlantic Beach expect to keep the incidence of leakage under control. Such a program will definitely prevent future leak losses from becoming a major contributor to the system's unaccounted for water losses. In our effort to provide the most comprehensive service possible, we requested in advance to have your personnel prepare the areas to be surveyed by taking measures to ensure that the majority of main line valves were accessible. Efforts were made in this advance preparation. This was greatly appreciated. CONCLUSION Hughes Supply, Inc. 10013 MLK Jr. Way S CUGHES Seattle, WA 98178 T 206 725 3441 T 206 725 5932 LEAK SURVEY CONCLUSION Our thanks to Donna Kaluzniak and all persons involved with this project for their assistance in gathering all the necessary paperwork and personnel to create, with Hughes, a mutually beneficial leak detection project. With this survey you have demonstrated concern for prudent water utilization and conservation. Capitalizing on the most advanced leak detection technology available today, Hughes has successfully completed this Leak Detection Survey. The contents of this Final Report provide the City of Atlantic Beach with a permanent record of the activities performed to complete a Leak Survey along with the results achieved. An important characteristic of this Leak Report is that the facts contained herein can be used in formulating a database for decision making regarding: the need for possible future meter programs, rehabilitation and pipe line replacement and /or the investigation of new water sources, etc. These types of decisions, regarding your utilization of water, now can be predicated more on facts rather than supposition or conjecture. Prompt repair of any leaks reported provide an immediate benefit to the City of Atlantic Beach, which includes recovery of most water revenue and water conservation, etc. Having achieved these results, we recommend that you continue to set up the infrastructure necessary to continue investigating leakage in the water distribution system. Implementation of any on -going leak survey program will ensure that leak losses are kept to a minimum, and the added enhancement of saving costs due to emergency call outs. Hughes Supply, Inc.,U tility Services Group is proud to have served the City of Atlantic Beach in this way and we wish to thank you for your substantial assistance and cooperation in this project. If you or your staff has any questions regarding this Final Report, please feel free to call us at (800) 621 -9292 or (206) 725 -3441. Best Regards, A0p741 Rob Meston Manager
