INC/ September 10, 1996 Mr. James R. Nuse Director of Public Works City of Round Rock 2008 Enterprise Round Rock, TX 78664 Ref.: Professional Services Proposal for Leak Detection Survey of High Leak Potential Areas of the Round Rock Water Distribution System. Dear Mr. Nuse: JBS Associates, Inc. is pleased to have been selected to provide a proposal for the above referenced project. Please find enclosed two copies of our proposal for your reference. The overall objective of the proposed water system survey is to conduct a sounding survey of selected areas of the City's water distribution system to determine and locate significant non - visible leaks, as described in the attached Scope of Work. Based on the City's urgency to address the high levels of leakage and our anticipated schedule of upcoming projects, we are available to start this project in the first week of October and expect to complete the work by the end of November. Naturally project status and availability can change on a weekly basis. If JBS Associates, Inc. is awarded this work, we will be pleased to confirm this availability upon confirmation of award. Sincerely, IATES, INC. le ent cc Mr. Fred Russell, Water Superintendent JAS /es enclosures 4715 Strack Road, Suite 100 • Houston, Texas 77069 • 713/580 -4200 • Fax: 713/440 - 3826 Executive Summary JBS Associates combines the talents of highly experienced professionals in the field of water loss control and leak detection. This combination includes 20 years' individual experience in this area utilizing all available technologies. Leak detection has always relied heavily on the experience factor. Anyone can acquire the skills to identify obvious leak noise, but more typically in the water utility environment, the Industry has to deal frequently with a wide variety of less than straightforward leak situations. The following proposal outlines our approach for the requested leak detection survey and highlights the exceptional expertise at our disposal. In keeping with the results and recommendations of the 1996 water audit, the areas with highest leakage potential are to be surveyed. These comprise all of the central area of Round Rock with the addition of Oak Creek and Oaklands subdivisions. In all, these areas are estimated to include 90 miles of water mains over 2" in diameter. Prior to commencement of field work we will conduct a review of water system mapping and the results of the water audit to develop an appropriate survey plan for the selected areas. This initial process will: • Accurately identify the areas to be surveyed on the distribution maps within the City's overall distribution system. This will provide for better management of field operations. • Establish the priorities for each zone based on traffic considerations, geographic location, accessibility, etc. The actual survey operation will be divided into two major activities: • Sounding operations (leak detection phase) to localize suspect locations within the area being surveyed. • Investigation of suspect locations identified in first phase to confirm the presence of leaks and locate them. Non -leak related occurrences will be eliminated from further investigation unless there is an indication of a water system abnormality which warrants the City's attention. During the course of the entire survey project, a simple but effective reporting process will be established. By limiting this process to the essential data necessary for action or review by the City, staff productive time on site will be maximized. Upon completion of the leak survey and corresponding leak repairs, we will conduct a minimum night flow test similar to the one conducted during the audit. This test will provide verification of the impact of leak repairs and an assessment of the remaining potential leakage. The last phase of the survey is the preparation and submittal of a Final Report. All data collected during the project will be compiled to provide both an overview of its results, as well as detailed analysis with recommendations. We anticipate that this study will be completed within 60 days from date of commencement. Our comprehensive knowledge of water distribution systems and instrumentation, combined with our previous experience in the Round Rock system provide for the most effective solutions to problems associated with water loss or accountability. We look forward to the opportunity to pursue leak losses within the City of Round Rock water system.

Addendum - Sample Report Forms L SCOPE OF WORK Professional Services Proposal Water Distribution System Leak Detection Survey City of Round Rock, Texas September, 1996 The proposed leak detection survey is designed to focus on the areas identified in the recent water audit as having the highest leakage potential. The goal of this program is to conduct a "blitz" survey of these high priority areas to locate large, non - visible leaks in the shortest time possible, in order to provide an early return in water savings to the City. The areas to be surveyed include an estimated 90 miles (40 %) of the distribution system and comprise the following subdivisions: • Round Rock Proper • Egger Acres • Greenhill • Green Slopes • Mesa Park • Mesa Ridge • Sunrise Vista • South Creek The tasks required to conduct this survey are described below. We expect to complete the work within 60 days of commencement. Task 1- Review of Water System Mapping and Records • Chisholm Valley • Oak Creek • Oaklands • Round Rock West The water system mapping and associated data will be evaluated so that a coordinated survey plan can be developed which addresses such system variables as pipe material, appurtenance accessibility, water pressure, geography and ambient noise. Combined with our experience during the Round Rock water audit, this review will allow JBS to determine how to further subdivide the distribution network into appropriate leak survey areas. This subdivision of the water system provides for improved management of the survey operation. Additional benefits of this approach are that the City can project future surveys on these pre - established zones and compare progressive results from future surveys. Task 2 - Develop Final Survey Nan The data collected and reviewed in the first task will provide the basis for our survey plan. The plan will include a definition of the survey zones by type, size and extension of water mains as well as local conditions. The plan will provide plan completion goals and determine the actual milestone checkpoints of the project. It should be noted that successful implementation of the plan will depend to some extent on the appropriate support provided by the City (see Section II). Task 3 - Conduct Sounding Survey to Detect Distribution System Leaks By use of advanced electronic sounding equipment, JBS personnel will conduct a sounding survey of the water distribution system zone by zone. Our present understanding of the basic operating environment of the areas to be surveyed is as follows 1. Approximately 90 miles of water main between 2" and 16" in diameter. 2. Estimated breakdown of pipe types: 75 % Asbestos - Cement 20 % PVC 5 % Cast/Ductile Iron 3. Services are of polybutytene and polyethylene pipe. 4. System pressures: 60 psi average, 95 psi max., 40 psi min. 5. Distribution system valve accessibility: better than 95 %. Every effort will be made to complete the sounding survey and pinpointing tasks for each survey area prior to commencement of the next one. Some overlap m the transition phase between areas is anticipated, but should not create inefficiency. JBS will provide the professional skills and the necessary equipment to complete this project. Vehicles and equipment will be in good operating condition at all times. Leak detection equipment will include sensitive leak sounding instruments and micro-processor based correlator. Physical contact will be made with the system for sounding purposes at accessible valves, hydrants and services at intervals no greater than those indicated as follows. • Cast/ductile /galvanized iron mains 12" or less: 400 ft. • Cast/ductile iron or steel mains over 12" : 200 ft. • Asbestos- cement mains 8" or less: 400 ft. • Asbestos- cement mains over 8" : 300 ft. • PVC mains 8" or less: 200 ft. • PVC mains over 8" : 100 ft. In cases where valves or hydrants are found to be leaking or are not accessible, alternative sounding points (services, probe holes) will be used where available. Where physical contact points are not available, surface sounding techniques may be used to listen over the water mains at intervals no greater than 10 feet. Soundings taken and other relevant field observations will be plotted for reference on water system maps. This information will provide the basis for the following stage. Where major leaks are repaired by the Customer while the JBS is in the field conducting this survey, the repaired section will be re- surveyed to ensure there is no further leakage. During the course of the survey, incidental observations of unauthorized use or non - revenue water usage, such as flushing, street and sewer maintenance, fire fighting and training or other activities will be reported to the City in Daily Observation Reports (see Addendum). Task 4 - Investigation of Suspect Locations and Pinpointing of Confirmed Leaks All indications of potential leak noise will be verified subsequent to the initial survey (Task 3), at which time suspect leaks will be confirmed and located by JBS personnel. In exceptional cases or due to Iack of access points where it is necessary to verify leak location prior to excavation for repair, City will provide probe holes for sounding directly on the main. Such probe locations will be requested in writing to the City. JBS will perform a thorough inspection of each suspect location identified in Task 3 prior to pinpointing operations. Any locations investigated which are determined to be non -leak related deficiencies will be reported and if appropriate photographed. The reports will be compiled for subsequent analysis and recommendations. Task 5 - Project Reporting Procedures JBS will provide the City with weekly written progress reports and individual leak reports for each leak located (see Addendum I and II). Leak reports shall include a best estimate of leakage rate for repair prioritization purposes and a sketch showing the location. Task 6 - Review Progress and Results A leak detection survey on a wide scale is a dynamic process. Field conditions vary, anticipated results may not be realized or may be exceeded. The survey process will be monitored frequently during the project by the Project Manager to ensure that the best survey approach for the conditions is being implemented. If changes to the pre- defined plan need to made they will be communicated to the Customer and implemented accordingly. Task 7 - Minimum Night Flow Test Upon completion of this survey and corresponding leak repairs, the minimum night flow test will be repeated to assess the impact of the repairs. This will be a similar procedure to that carried out during the water audit study. Task 8 - Final Report Preparation and Submittal JBS will furnish to the City a Final Report detailing the work undertaken, the results obtained, observations concerning the water system surveyed and appropriate recommendations for the further development of leak reduction practices. Results available from leaks repaired by the City prior to completion of the field work as well as all relevant data collected during the course of the study will be compiled and analyzed. The report will also provide conclusions and prioritized recommendations. Particular attention will be directed to the on -going leak detection needs of the Round Rock water system. The Final Report will be presented in person to allow staff the opportunity to ask questions about the results and the recommendations presented. II. CITY'S RESPONSIBILITIES To ensure the best results from this survey program, we will need the City's support with certain tasks. The City's responsibilities include the following: 1. Prior to commencement, supply JBS Associates, Inc. with three complete sets of most current available plans of the water distribution system, showing size, type and location of mains, valves and fire hydrants. 2. During the course of the survey the City should make available to JBS Associates the log of leak related work orders maintained by the City, so as to track all visible leaks reported during the study. 3. Provide one experienced individual knowledgeable of the water system to be surveyed, for the purposes of valve /pipe location and access, access to customers' services, traffic control, etc. 4. Provide further access to the water system by probe hole or excavation on an occasional basis as requested by JBS for thorough completion of the survey. 5. In order to maximize the recovery of lost water through leakage identified during the survey, it is essential that all significant leaks are repaired by the City as the survey progresses, and prior to conducting the night flow test. 6. Officially notify local public safety agencies (Police & Fire Depts., etc.) of the nature of this project and provide assistance to JBS where this may be necessary for safe completion of the work. III. FEES FOR PROFESSIONAL SERVICES Based on the results of the recent water audit as well as information furnished to date by the City of Round Rock, JBS Associates, Inc. will perform the Water Distribution System Leak Detection Survey of approximately 90 miles of the City's water distribution system, to include final minimum night flow test, as described in this proposal for an aggregate fee not to exceed $15,300.00. If the total mileage of water mains in the described areas falls short of the 90 mile estimate, additional areas will be selected to make up the shortfall. If during the survey it becomes clear that the above mileage estimate is substantially below the real total to achieve completion of all the selected areas, JBS will perform the additional work, at the City's discretion, at the rate of $140 per mile. The Water Audit estimated the cost of water lost through leakage at $256,900 annually. A recovery of 6 percent (146 gpm) of the total unaccounted for loss will more than pay for the proposed survey.

System pressures: 60 psi average, 95 psi max., 40 psi min. 5. Distribution system valve accessibility: better than 95 %. Every effort will be made to complete the sounding survey and pinpointing tasks for each survey area prior to commencement of the next one. Some overlap in the transition phase between areas is anticipated, but should not create inefficiency. JBS will provide the professional skills and the necessary equipment to complete this project. Vehicles and equipment will be in good operating condition at all times. Leak detection equipment will include sensitive leak sounding instruments and micro-processor based correlator. Physical contact will be made with the system for sounding purposes at accessible valves, hydrants and services at intervals no greater than those indicated as follows. • Cast/ductile /galvanized iron mains 12" or less: 400 ft. • Cast/ductile iron or steel mains over 12" : 200 ft. • Asbestos - cement mains 8" or Iess: 400 ft. • Asbestos- cement mains over 8" : 300 ft. • PVC mains 8" or less: 200 ft. • PVC mains over 8" : 100 ft. ' In cases where valves or hydrants are found to be leaking or are not accessible, alternative sounding points (services, probe holes) will be used where available. ' Where physical contact points are not available, surface sounding techniques may be used to listen over the water mains at intervals no greater than 10 feet. ' Soundings taken and other relevant field observations will be plotted for reference on water system maps. This information will provide the basis for the following stage. ' Where major leaks are repaired by the Customer while the JBS is in the field conducting this survey, the repaired section will be re- surveyed to ensure there is no further leakage. ' 2 JBS Associates, Inc. City of Round Rock, Texas During the course of the survey, incidental observations of unauthorized use or non - revenue water usage, such as flushing, street and sewer maintenance, fire fighting and training or other activities will be reported to the City in Daily Observation Reports (see Addendum). Task 4 - Investigation of Suspect Locations and Pinpointing of Confirmed Leaks All indications of potential leak noise will be verified subsequent to the initial survey (Task 3), ' at which time suspect leaks will be confirmed and located by JBS personnel. ' In exceptional cases or due to lack of access points where it is necessary to verify leak location prior to excavation for repair, City will provide probe holes for sounding directly on the main. Such probe locations will be requested in writing to the City. ' JBS will perform a thorough inspection of each suspect location identified in Task 3 prior to pinpointing operations. Any locations investigated which are determined to be non -leak related ' deficiencies will be reported and if appropriate photographed. The reports will be compiled for subsequent analysis and recommendations. ' Task 5 - Project Reporting Procedures JBS will provide the City with weekly written progress reports and individual leak reports for each leak located (see Addendum I and II). Leak reports shall include a best estimate of leakage rate for repair prioritization purposes and a sketch showing the location. Task 6 - Review Progress and Results A leak detection survey on a wide scale is a dynamic process. Field conditions vary, anticipated results may not be realized or may be exceeded. The survey process will be monitored frequently during the project by the Project Manager to ensure that the best survey approach for the conditions is being implemented. If changes to the pre- defined plan need to made they will be communicated to the Customer and implemented accordingly. Task 7 - Minimum Night Flow Test Upon completion of this survey and corresponding leak repairs, the minimum night flow test will ' be repeated to assess the impact of the repairs. This will be a similar procedure to that carried out during the water audit study. 1 1 3 JBS Associates, Inc. City of Round Rock, Texas Task 8 - Final Report Preparation and Submittal JBS will furnish to the City a Final Report detailing the work undertaken, the results obtained, observations concerning the water system surveyed and appropriate recommendations for the further development of leak reduction practices. Results available from leaks repaired by the City prior to completion of the field work as well as all relevant data collected during the course of the study will be compiled and analyzed. The report will also provide conclusions and prioritized recommendations. Particular attention will be directed to the on -going leak detection needs of the Round Rock water system. The Final Report will be presented in person to allow staff the opportunity to ask questions about the results and the recommendations presented. 4 JBS Associates, Inc. City of Round Rock, Texas II. CITY'S RESPONSIBILITIES To ensure the best results from this survey program, we will need the City's support with certain tasks. The City's responsibilities include the following: ' 1. Prior to commencement, supply JBS Associates, Inc. with three complete sets of most current available plans of the water distribution system, showing size, type and location of mains, valves and fire hydrants. 2. During the course of the survey the City should make available to JBS Associates the log of leak related work orders maintained by the City, so as to track all visible Leaks reported during the study. 1 3. Provide one experienced individual knowledgeable of the water system to be surveyed, for the purposes of valve /pipe location and access, access to customers' services, traffic control, etc. 4. Provide further access to the water system by probe hole or excavation on an occasional basis as requested by JBS for thorough completion of the survey. 5. In order to maximize the recovery of lost water through leakage identified during the 1 survey, it is essential that all significant leaks are repaired by the City as the survey progresses, and prior to conducting the night flow test. 1 6. Officially notify local public safety agencies (Police & Fire Depts., etc.) of the nature of this project and provide assistance to JBS where this may be necessary for safe completion 111 of the work. 1 1 1 1 1 1 ' 5 1 IBS Associates, Inc. City ofRound Rock, Texas III. FEES FOR PROFESSIONAL SERVICES Based on the results of the recent water audit as well as information furnished to date by the City of Round Rock, JBS Associates, Inc. will perform the Water Distribution System Leak Detection Survey of approximately 90 miles of the City's water distribution system, to include final minimum night flow test, as described in this proposal for an aggregate fee not to exceed 515,300.00. If the total mileage of water mains in the described areas falls short of the 90 mile estimate, additional areas will be selected to make up the shortfall. If during the survey it becomes clear that the above mileage estimate is substantially below the real total to achieve completion of all the selected areas, JBS will perform the additional work, ' at the City's discretion, at the rate of $140 per mile. The Water Audit estimated the cost of water Lost through leakage at $256,900 annually. A recovery of 6 percent (146 gpm) of the total unaccounted for loss will more than pay for the proposed survey. 1 1 1 1 1 1 1 1 1 1 1 6 JBS Associates, Inc. City of Round Rock, Texas IV.
