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.

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.

• 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
JBS Associates, Inc. City of Round Rock, Texas
1 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.

I. 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 • Mesa Park
• Egger Acres
• Greenhill
• Green Slopes
• Mesa Ridge
• Sunrise Vista
• South Creek
Task 1- Review of Water System Mapping and Records
• Chisholm Valley
• Oak Creek
• Oaklands
• Round Rock West
The tasks required to conduct this survey are described below. We expect to complete the work
within 60 days of commencement.
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 Plan
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).
JBS Associates, Inc. City of Round Rock, Texas
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 polybutylene 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 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.

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.

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.

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.
