PROCEDURES AND METHODS
(Water Distribution Lines)
Utility Services Associates (hereafter referred to as CONSULTANT) will survey for
and pinpoint water leaks using highly sophisticated leak detection technology. We use
a sonic leak detection sound amplification instrument in conjunction with a transducer
capable of 3VG or greater (volts per "G") sensitivity minimum output for survey. We use
various types of equipment including ground microphones, computer based correlators,
etc. for leak pinpointing. We utilize pipe tracing and box locating equipment with each
mobile unit. Our equipment is operated by trained experienced professionals. A detailed
report of leak locations, estimated GPM loss, and area covered is supplied daily. A final
report is provided on a monthly basis or at the completion of the project. The report
includes: a summary of the project, survey review, area survey sheets with observations
noted, sheets with data on each individual leak with a drawing of its location, and a
conclusion.
II. SPECIFICS
A. The first step in our survey is to review the distribution maps of our clients
system for familiarization of the pipe network and available appurtenances (valves,
services, hydrants, etc.) to be used as contact points.
B. As the leak survey progresses, CONSULTANT determines the distance that
even quiet leak sounds travel in various pipe materials, pipe sizes, and pressure zones
in each area of your system. This will be done by slightly turning on fire hydrants, hose
bibs, etc., creating a simulated quiet leak sound. Appurtenances in that area are then
checked with a sound amplification instrument to see how far the simulated leak sound
travels, thus determining how often CONSULTANT will make contact with appurtenances
in a given section of our client water distribution system.
C. CONSULTANT then conducts a comprehensive survey by making physical
contact with all available main line appurtenances (valves, hydrants, etc.) and selected
customer services. CONSULTANT uses a sonic leak detection sound amplification
instrument designed for this purpose with a transducer rated at a minimum of 3VG or
greater (volts per "G"). (When surveying PVC pipe lines, CONSULTANT will make
contact with all service shut ofts.)
D. Contact is then made with pipe appurtenances at intervals no greater than 350
feet where contact points are available and accessible, or at pre-determined distances
as noted in Paragraph B (whichever distance is less). This allows for even more quiet
leaks to be located.
E. When normal contact points are not available or can not be created within a
reasonable distance as described in Paragraph D, we will make an attempt to use a sonic
2
ground listening instrument making physical ground contact at intervals no greater than
6 feet directly Qver the pipe. If conditions do not allow this procedure our Field
Technicians will advise CLIENT at time of project and will detail in the Final Report. If
excessive ambient noise precludes the effectiveness of the ground listening device in an
area during daytime hours, we will schedule this portion of the survey for night time
hours. We will pre-approve these situations with the Client. (Ground listening devices
are employed when ground cover is pavement, cement or a similar hard surface.) Direct
contact to the main line at intervals outlined in Preparation for Service will result in the
most thorough survey.
F. When ground cover is not a hard surface, probe rods will be used at 6 feet
intervals when normal contact points are not available (as described in Paragraph D).
A sound amplification instrument with 3VG or greater (volts per "G") transducer is used
on probe rods. Probe rods will be driven into ground a minimum of 6" directly over the
pipe when ground conditions allow.
G. A detailed report of decibel levels at suspected leak sound locations and
observations are compiled during the survey for reinvestigation and possible pinpointing
at a later time. This reinvestigation is to increase the speed of the survey and it will
eliminate correlating on most false leak sounds (Le. Service Draw).
H. All indications of leaks found during survey will be verified a second time, after
which the leak noise shall be pinpointed with a computer based leak sound correlator
where applicable. Pinpointing leak locations through interpretation of sound intensity,
either by ear, decibel metering, or other like methods, is not used when contact points are
available for use with correlator.
I. The equipment utilized does not normally require valves to be operated during
surveying and pinpointing. However, on occasion, services or valves may need to be
operated to eliminate service draw noises or to change velocity noise.
J. The correlator equipment used will have the capability to prompt the operator
to input the variables when different pipe sizes and/or pipe materials are 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 four various pipe sizes
and types at one time in a given span. To insure effective performance in all field
environments encountered in your distribution system (Le. traffic noise, draw, pump
operation, industrial noise, etc.) the correlator equipment provides 12 multi-range High
and Low Pass filters. Digitally controlled variable band pass filters between 72Hz and
7.1 kHz, providing up to 53 selectable filter ranges, full operating frequency range (all
pass): 10Hz-20kHz.
K. CONSULTANT will furnish to the CLIENT daily leak reports and shall also
furnish a final report within fourteen( 14) days from end of the project. This report
includes:
1. Executive Summary showing individually recorded time for, correlating,
surveying, and other time spent on the project. This summary also includes, footage
covered, approximate GPD loss, types of leaks found, quantity of leaks found, and
remarks recommending improvements that may be made to your distribution system.
3
2. Survey Review explaining the Procedures and Methods used during this
study.
3. Area Survey Reports indicating pipe line areas covered, amount and type
of contact points used, leak sound locations with decibel levels, approximate time spent,
and observations of water system irregularities. A separate survey sheet is used for
areas covered with only a ground listening device or probe rod, indicating ground cover.
4. Leak Reports with detailed drawing showing each leak location that was
pinpointed, the type of leak found, approximate time spent pinpointing, and estimate of
the GPM loss and computer justification when applicable. (This same leak report shall
be supplied daily to the CLIENT when leaks are found.)
L. Whenever the CLIENT repairs any leak detected by CONSULTANT prior to
completion of the field work, CONSULTANT shall resurvey that section of the system, to
ensure no very quiet leaks were missed due to over powering noisy leak sound.
M. CONSULTANT will furnish a trained field technician, leak detection
instruments, and equipment and tools to complete the survey and leak pinpointing.
N. CONSULTANT will perform their best effort to pinpoint all existing leaks.
O. To provide an accurate, comprehensive leak survey, a relatively large
contiguous area must be covered. Spot checking to locate a leak is not considered to
be an effective survey and requires special pricing.
III. SERVICES TO BE PROVIDED BY THE UTILITY
A. CLIENT will furnish, at no cost to CONSULTANT, a complete set of maps and
line data on the water distribution system to be surveyed, showing line size, type, and
location of mains, valves and fire hydrants.
B. CLIENT will make the water system's valves, valve boxes, customer service
stops, and boxes accessible by hand, operating key or probe and, if necessary, assist in
field locating of all pipelines within the designated service area.
C. CLIENT shall provide a helper to located and operate valves, services,
hydrants, etc. when necessary, and generally provide information to assist technician
when needed.
D. CLIENT shall provide a helper and necessary equipment (flags, traffic cones,
etc.) as required to meet local, state and federal regulations in controlling vehicular traffic
for man and equipment safety.
E. CLIENT may be requested to provide additional access points on the water
system as may be required on an occasional basis by CONSULTANT in order to
effectively complete the survey when normal contact points are not available within a
reasonable distance for correlation.
IV. RELATIONSHIP OF CONTRACTING PARTIES
The parties intend that CONSULTANT, in performing services herein specified,
4
shall act as an independent consultant and shall have control of his/her work and the
manner in which it is performed. CONSULTANT shall be free to contract for similar
