RE: Request for Proposals (RFP) 20-0183 Acoustical Leak and Correlation Survey
Dear Ms. Czechowicz:
In response to the above referenced solicitation, Wachs Water Services (VVWS) is enclosing our
proposal to provide Acoustical Leak and Correlation Survey services to the City of Fort Worth, TX (the
City).
Your RFP evaluation criteria emphasized the desire to select a firm offering the best combination of
project requirements, approach, qualifications, staff capabilities, and cost effectiveness. Our proposal
reflects an experienced technical team that has been working throughout the State of Texas.We believe
we are thoroughly qualified to perform the work outlined in the RFP. You can depend on WWS for
several uncommon advantages:
• Key Personnel: As a whole, our technicians are relentlessly proficient. They are the best of the
best, hand-picked from a national pool, rigorously trained, highly experienced and motivated to
succeed. You will find working with them is an experience where you are rewarded with
knowledge only gained by working with a national leak detection company such as VWVS. In
short, our team will find more leaks, find them more quickly, pinpoint them more accurately and
deliver more meaningful reports and data to the City.
■ Qualifications: The qualifications of our company and our personnel is the result of experience
gained over many years focusing exclusively on water distribution services. We have significant
experience working throughout Texas with offices registered in Houston and Dallas. We are
currently beginning work at the Dallas/Ft.Worth airport, leading a complete Non-Revenue Water
Loss Control (NRWLC) Program for the City of Galveston with very similar goals over the next
five years as set forth by the City of Ft. Worth and nearly 7,000 miles of pipe surveyed for San
Antonio, TX. WWS has surveyed over 17,000 miles of main, listened for leaks on over
721,000 assets and pinpointed 6,517 leaks!
• Non-Revenue Water Loss: WWS understands the estimated real water loss for Forth Worth
Water is 7.87 billion gallons in the calendar year 2020. Your goal is to reduce real losses by an
average of 2 galslconnlday each year for the next five years. Cur team looks forward to providing
the critical acoustical and leak detection services but also providing superior water loss
mitigation and NRWLC knowledge. WVVS is committed to providing the highest quality
professional services in an efficient, defensible, and cost-effective manner,whereby the City will
realize the proposed water usage goals and be positioned to cost effectively sustain the optirnal
performance of the water delivery system indefinitely.
• Our Approach: The human ear is most sensitive to frequencies in the 2K to 5K hertz
range. Unfortunately, most leak sounds fall well below this range with leaks caused by
circumferential cracks producing sound between 200 and 500 hertz; the most common water
main break. WWS understands that a primary function of any leak survey is to identify
leaks, We also know that circumferential failures are caused by bending forces on the pipe and
i v v i WachsWater
are typically located centrally in the pipe segment often in segments connected to vaults, thrust
blocking and any heavy appurtenance that may settle. Our understanding of human limitations,
leak sound ranges, pipe failure modes and the attenuation of sound after bearing changes in
the pipe is the foundation of our approach to selecting leak staff, selecting equipment and
establishing the density of survey points. We deliver greater value by finding more leakage per
mile.
s GIS Approach: In addition, VWVS creates an intrinsic link between every point
surveyed, early coordinates and the Board's existing GIS — should it exist. VVWS
will use the City's GIS instead of hard copy maps, deployed in the field allowing the
field crews to identify which asset they listened to and make note of any
discrepancies or problems found.
In conclusion, there is value in making systems match ground conditions and VWVS understands this
as a common truth about leak detection to deliver more value than any vendor who may be
proposing. Our team will utilize project-tested innovative tools to deliver cost-effective solutions for
successful leak detection, map every listening point in real time, and allow the City staff to monitor the
program and view leak reports in real time using ProjectTrackerr"'.
We are very excited for this opportunity because it is a perfect match with our experience, the services
we provide and the team we are proposing. We recognize the importance of this project, and have a
strong desire to serve the City. We want to thank you for the opportunity to submit our proposal and
look forward to a favorable decision on behalf of WWS.
Sincerely,
W, Clayton Coe I Business Development Manager

WORK PLAN
Project Approach
'WIS's delivery process revolves around a resolute commitment to meeting all of the City's program
objectives. WWS understands a Leak Detection Survey is an important revenue reclamation activity
,or the City. We will develop a program plan that meets your objectives and delivers the results you
want. We are the nation's experts at delivering distribution system programs and are experts at
achieving program objectives. WWS brings added value to all our programs through our distribution
system experience and best practices. We are pleased to share our industry knowledge with the City
we have attained from municipalities across the country.
The goal of any leak detection survey is to accurately and economically identify as much leakage as
possible. However, our experience in the field at WINS informs us the key to a successful leak detection
survey is to balance the investment of labor with the reward of identified leakage. Determining the
appropriate `resolution' of leak surveys is vital. Some water systems can effectively be surveyed with
low resolution approaches (such as hydrants only), while other systems require a much higher
resolution approach to be effective due to their use of different distribution materials and asset types
(such as hydrants, valves and service curb stops). At WWS, we understand how these delineations
are made from a practical standpoint capturing as much leakage as possible.
There are three primary environmental
variables driving the resolution required for an
effective leak detection survey as seen in
Internal Survey

Our approach is strengthened further by the fact that every potential leak event is captured in the field
using mobile technology. The information captured is not limited to the location of the potential leak
event but also includes the date and time, key data attributes and the details of the personnel who
captured it. This allows for an evaluation of leaks, assets, distances, materials and other factors in
determining the best way to pinpoint large groups of leaks. This approach offers numerous benefits
including:
• All potential leak event' data as well as 'validated leak' data can be sheared with the City for
further use on Other applications such as Hydraulic modelling or Capital Improvement Planning.
• Leaks flagged as high priority can be shared with the City so personnel may easily locate and
more promptly repair them.
• Most importantly W VS monitors and analyzes this data internally to determine adjustments that
need to be made by field personnel performance to ensure the optimal and agreed upon survey
resolution is being met. By tracking the mileage, number of potential and validated leak events
for each we can calculate a running project average for each metric. Individual personnel
performance can be measured against this running project average as well as analyzed on their
own merit as seen in Figure 2. An example of this type of analysis is shown below:

WWS employs a two-phase approach to leak detection programs. The first phase is a comprehensive
survey where all targeted listening points are surveyed with sonic acoustic equipment and any assets
with possible or strong leak noises are flagged for follow-up. In addition to potentials leaks, asset
defects and mapping discrepancies are also documented.
The second phase is to provide quality assurance (QA)/quality control (QC) of all flagged leak noises
from the first phase. After leak noises are confirmed during the second phase, WWS leak technicians
will line locate the immediate area and begin pinpointing with a correlator and ground microphone. Our
pinpointing technicians typically mark within a 5-foot radius.

Quality Control
Quality is an important factor when it comes to providing any service. With the high market competition,
quality has become the market differentiator. Quality control is essential to meeting and exceeding the
C ity's expectations, minimizing waste and increasing productivity.
To ensure that the leak detection survey work that we perform provides the accurate results required
by the City, we propose to resurvey up to two percent of the system with senior leak detection
technicians. This ensures that a minimum 90 percent of initial survey results indicating no leak
present are in fact leak free. In the event the resurvey findings indicate less than 90 percent results,
the area will be resurveyed at no cost to the City.
Project Management Methodology
The WWS management is organized to reduce the timeframe and risks which revolve around significant
system activities. VWdS managers understand the tasks associated with carrying-out leak survey and
pinpointing services.
They understand how tasks are interconnected and what type of oversight is necessary for them to be
performed expeditiously and successfully. This knowledge and understanding have been gained
through successful experience working in a production environment nationwide.
There is no amount of training which can replace experience when it comes to developing a solid
knowledgebase. WWS's provides more experience and more qualifications, more capacity and more
capabilities which amounts to more successful productivity and a LOW EFFECTIVE PRICE to the City.
The program manager will manage the startup and planning and implementation of the Leakage
Assessment Services program. The program manager will follow the program plan, conduct pre-
program discussions, develop the schedule and ensure delivering on the City's objectives. The project
manager is responsible for delivering reports and official communications of all types related to the
work.
WWS is a GIS-centric organization. G IS data collection and management isn't a task in our workflow-
- it's the foundation. Our approach is to assign, document and manage all activities from a central GIS
database.
Wachs Wafer Services approach to leak surveys is unique. In addition to collecting
data on leak sounds we individually capture GPS ;�d additional information at each
sounding point(hydrant, valve. curb-stop, etc.). This information is available to City
staff in real-time through ProjlctTracker71'

Summary of Procedures
The purpose of the leak detection survey is to accurately identify specific locations as requested by the
City,which then can be excavated by the City staff and remediated as necessary to reduce any amount
of water loss and recover lost revenue.
WINS will ensure the highest efficiency and effectiveness of leak detection efforts. Prior to the daily
execution of leak detection survey activities all the pre-work and planning will have been completed.
The Project Manager will oversee all activities. The sequence of work, on a daily basis, will include all
the following activities.
■ Safety meeting
• Provide appropriate traffic control and safety measures �UK
• Locating starting asset to begin survey
■ Listen to assets to identify audible leafs
■ If a leak sound is heard, identify other nearby assets to
narrow the leak location point(valves/meter boxes, etc.)
Begin correlation between the two (2) assets with
highest audible sound of suspect leak
Place correlator sensors on two (2) identified assets _ -
(this is In areas where metallic pipe is known)
• On the control box, enter all the known information
(distance, pipe material, etc.)
• Begin correlation

the City.
Task 2 —Acoustic Leak §urveW
Task 2.1: Survey Site Traffic Control and Security
VVVVS recognized that every environment presents its own challenges with regard to a safe worksite.
VVWS tailors' safety measures to each environment's specific challenges. To ensure safe worksites,
VVVVS will conduct a physical security survey and assessment to determine areas that have a potential
for safety issues.
For work areas that are determined to have potential safety issues, VVVVS will adopt additional security
measures, adjust working hours and provide additional employee training to ensure workers' safety as
they conduct surveys in these areas. Our workplace safety strategy includes measures to detect,
assess, and manage threats. Prior to working in each area, VW S will:
• Conduct a physical security survey and assessment of the area.
• Establish procedures for addressing threats and threatening behavior.
• If necessary, provide access to outside resources, such as threat assessment professionals.
• Train field personnel on early recognition of warning signs of problematic situations.
Train field personnel on ways of preventing or defusing volatile situations
Provide a standard response action plan for volatile situations, including availability of
assistance and communication procedures.
All WWS field crew personnel are trained in specific traffic control procedures. Crew members will be
provided traffic control signs, rotating warning lights,corner strobe lights, cones, and traffic arrow boards
on the trucks and will use these traffic control tools to set up safe workplaces as needed. If traffic control
is very difficult in certain areas, then VVVVS may shift to night operations (for ease of traffic control).

Task 2.2: Leak Survey
VV WWS employs a proven two phase approach to large leak detection +
programs. The first phase is a comprehensive survey where all targeted w
listening points are surveyed with sonic acoustic equipment and any
assets with possible or strong leak noises are flagged. Listening points
shall include water main valves, meters and hydrants and any other
appurtenance necessary to perform a thorough leak survey. When
additional acoustic information is required, and water main access is
limited, ground microphones will be utilized on ground surfaces for
surveying. In addition to potentials leaks, asset defects and mapping
discrepancies are also documented.
Task 2.3: Leak Correlating/Pinpointing Leaks
Correlation is a way of pinpointing leaks in water mains. A leak in a
pipe under pressure creates noise that travels through the pipe walls,
the surrounding ground and along the contents of the pipe. if two highly
sensitive correlation microphones are attached to two different listening
points on a pipe with an identified potential leak, sound from the leak
takes longer to travel to the microphone furthest from the leak; this is
referred to as the"time delay". Utilizing this and other information (pipe
diameter, material and length of section under test), the exact leak
position can be calculated by using the correlators. Once a suspected
leak is correlated, a WWS technician will then use a ground microphone
to confirm the leak. The leak will then be mapped via GPS and marked
accordingly. Since the accuracy of pinpointing relies primarily on the
acoustic characteristics of the pipe, the accuracy of the pipe size,
length, material and lateral configurations, overnight, and possibly .1 '
longer term logging may be utilized to record acoustic information, at the discretion of the City.
Task 2.4: QAIQC
Quality is an important factor when it comes to providing any service. With the high market competition,
quality has become the market differentiator. Quality control is essential to meeting and exceeding
the City's expectations, minimizing waste and increasing productivity.
To ensure that the leak detection survey work that we will perform provides the accurate results required
by the City, WWS proposes to resurvey up to two percent of the system with senior leak detection
technicians. This ensures that 90 percent of initial survey results indicating no leak present are
in fact leak free. In the event the resurvey findings indicate less than 90 percent results, the area will
be resurveyed at no cost to the City.

work for this project from receipt of an assignment through data delivery to the City.
Our key people have been working together in many other utilities performing all aspects of this scope
of work. The result is clear lines of communication and responsibility.
WINS teams have many years of experience bringing programs to their successful conclusion; this
increases the expected productivity because higher productivity and higher quality is equivalent to
Lower Effective Prices. WVVS has developed a management philosophy built on the institution of
professional management practices and implemented them company wide. 1NWS project managers
understand how earned value is tracked and what actions need to be taken when variances are
observed in any given task. The result is on time and on budget delivery.
As part of our quality control procedures mentioned previously, WWS will resurvey up to 2 percent of
the system to ensure 90 percent of the initial survey results indicating no leak are leak free. If findings
indicate less than 96 percent, the area will be resurveyed at no cost to the City.

Water conservation is a long term strategy. Southlake Water

Client
Wachs Water Services started a pilot program with the City to
SouthlakeI assess in-line valves. While the pilot was in progress, the City
ContactReference experienced a leak that was difficult to locate. With the City and
Flanagan,Kyle WaterWachs working together, the leak was located quickly which
Supervisor reduced the consequences of the failure and helped to maintain
81; the City's proactive reputation.
This particular leak was on a shared line between Southlake
Project Type(s) and another sister city. It was a major transmission line for both
Valve program, cities and was even located near some major surface
priorinspections . UDF and infrastructure that if not located properly would have
leak detection invest •- necessitated demolition of said infrastructure for further sub-
surface investigation. Southlake was able to call on the
multifaceted in-depth experience of Wachs Water Services
Oct- ! under a single contract to not only assess valves and hydrants,
perform unidirectional flushing work but also leak detection
$80.000 leak detection survey investigation when the consequence of failure was at its

assessments In many cases it makes sense for cities, small and large,to look

those services can be performed on a temporary basis.
Southlake began by providing WWS with defined areas for valve assessments to provide the greatest
benefit to their G I S Department. Since we were already under contract with the City and had expertise
in leak detection, they called on us to perform those services.

Noise Detection Equipment
The following leak noise detection equipment will be used to perform the teak survey.
FCS Lmic
WWS uses the Lmic for general leak sounding operations within our programs. The Lmic can be fitted
with either a tripod foot (for use as a ground microphone) or probe rods (for sounding at fittings).
Vivax Metrotech HL-5000
This equipment utilizes state of the art DSA (dual segment analysis) technology to simultaneously
measure current and minimal noise values. This dual analysis allows the user to understand the total
ambient noise (current) vs. the noise associated with the appurtenance being evaluated (minimal). The
measurements are displayed simultaneously on the devices digital display. Unlike most listening
devices which simply amplify sound, the HL-5000 can analyze the real-time frequency of a sound
measurement which will assist the user in determining correlation filters. This device also allows for 9
simultaneous DSA visual measurements which can be used as historical references during ground
microphone pinpointing.
Sewerin Listening Device Aquaphon
Men a pressurized water pipe develops a leafs, the water flows out into the surrounding soil at high
speed,which causes the pipe material to vibrate at the exit point.This vibration, or sound, is transmitted
by the pipe. This"noise"can a€so be heard at remote contact points. The leak may also cause the water
jet and pipe, in the vicinity of the leak, to induce vibration into the surrounding soil.
This "noise" is transmitted to the surface, where it can be identified. The Aquaphon interprets the
intensity of the noise and translates it to a numeric value which is then displayed on the LC❑ screen.
The previous sounding record is stored for comparison to the active or next sounding record which
assists the technician in leak localization.
SubSurface Leak Detection LD-12
The SubSurface LD-12 Water Leak Detector offers the top features in amplification and audio clarity.
One of the finest sonic listening devices on the market today, the large meter display of the leak sound
intensity is easily visible in all outdoor lighting,from bright sunlight to total darkness. The LD-12 includes
a base plate for"ground miring"on city streets or concrete slabs and both a magnet base and a contact
rod for water leak"surveying" at hydrants, valves, and meters.
EquipmentCorrelating
WWS will provide specialized, advanced, sensitive electronic leak pinpointing equipment and skilled
operators to effectively and efficiently perform Task 2.3 leak pinpointing. Electronic correlation
equipment is one method employed to pinpoint leaks. After a leak has been correlated a final audio
detection will be performed to verify the leak.

SubSurface Leak Detection LC-2500
The Su>bSurface LC-2500 Leak Noise Correlator is very lightweight and compact, yet it offers full
capabilities for programming and correlating leak noise from many different pipe materials and pipe
diameters. Strong and accurate sensors, powerful radios and fast processing of sounds make the LC-
2500 truly the best performing correlator on the market.
Sewerin Leak Correlator SeCorr -08
The SeCorrg7 08 is Sewerin's new fully digital correlator offering unprecedented performance in finding
water leaks. It is also highly effective on plastic pipes and trunk mains. The fully digital signal processing
and data transmission largely eliminate the limitations experienced with conventional analogue
correlators. The SeCorr@ 08 can also pinpoint leaks outside of the sensor's range. This can help when
system configurations do not allow the sensors to be placed on either side of the suspected leak
location.
Metrotech HL6000X— PC Correlator
The correlator uses sophisticated radiotechnology for long range operation. The user can perform
correlations on and off-site with saved data files. There are enhanced process integrations with a GPS
antenna and the ability to integrate GIS software. If pipe data is unknown, the user can carry out
automatic speed measurements in conjunction with the automatic filtering and multi-position correlation
results to find the correct pipe data to perform correlations.
Line Locating Equipment
Line locators are a critical component of an effective leak pinpoint equipment arsenal. Correlators rely
on accurate input variables and precise bury depth when making an accurate leak location.
Metrotech VM-810
Metrotech. one of the original names in Pipe & Cable locating, has been producing the well tried and
tested VM-810 for over forty years. The instrument includes a distance sensitive left/right guidance
system (pioneered by Metrotech) and automatic gain adjustments to provide accurate easy locating.
The VM-810 is designed as a single frequency true left/ right locator which makes the unit easier to
ground while minimizing user error.
.Equipment Maintenance & Procurement
Our leak detection tools are maintained and stored per manufacturer specifications. This includes
necessary software and hardware updates. WWS leak technicians also perform weekly operational
assessments of project equipment to ensure all leak detection equipment is functioning properly.
Defective equipment is sent to the manufacturer or other authorized repair facility for immediate
attention. New equipment is acquired after careful evaluation of product developments and
advancements enter the market. WINS requires vendors to field demonstrate the abilities of their leak
detection equipment in a head to head comparison with our current leak detection tools. Acquisitions
are made if the equipment can provide increased functionality, efficiency, or accuracy.

EXHIBIT B: VALUE/COST PROPO5TION (OPTIONAL)
The City is contracting for a leak detection survey due to the current level of water loss across the
system. The City believes this survey will ultimately lead to lower net operating costs as leaks are found
and water loss is reduced. Consequently, undetected leaks will cause an adverse financial impact on
the City.
The sounding required for external leak inspection is often performed in conjunction with the
assessment and maintenance of valves and hydrants. Combining valve and hydrant assessments with
the leak detection survey may reduce the costs for assessing and maintaining valves and hydrants as
presented below. Further details on deliverables is available on request.

To further support the City with their effort to reduce real losses, particularly on system "blind spots"
(larger diameter, non-metallic piping and/or pipe lengths not easily accessible, such as river crossings)
Wachs Water Services offers the following services:
Internal acoustic leak inspection for larger diameter pipelines using either a free-swimming(SmartBa119)
or tethered (Sahara® System) delivery platform. Larger diameter water mains typically do not offer
enough assets on which to sound the pipeline and noise generated by leaks in larger lines tend to
attenuate rapidly, making conventional external leak inspection techniques ineffective. Internal acoustic
leak detection represents state-of-the-art leak technology for identifying and locating leaks and air
pockets in large diameter pipelines {? 20-inches), as the acoustic sensor passes directly by an active
leak. Either delivery platform is deployed on a live pipeline, as there is no requirement to take the line
out of service. The fees offered below require that the City furnish appropriate access for deployment
of the inspection tools, temporarily close off flow to laterals and provide an appropriate flow rate. All
identified leaks are marked on the ground and a letter report summarizing the results of each inspection
provided. Additional information regarding the SmartBall and Sahara on request.

CODE: P TYPE: CONSENT PUBLIC NO
HEARING:
SUBJECT. (ALL)Authorize Execution of a Service Agreement with Pure Technologies US Inc. d/b/a
Wachs Water Services for Acoustical Leak and Correlation Survey Services in an Amount
Up to $144,364.00 for the Water Department
RECOMMENDATION:
It is recommended that the City Council authorize execution of a service agreement with Pure Technologies
US Inc. d/b/a Wachs Water Services for Acoustical Leak and Correlation Survey Services in an amount up to
$144,364.00 for the Water Department.
DISCUSSION:
The Water Department approached the Purchasing Division to finalize an agreement for Acoustical Leak
and Correlation Survey Services. In order to procure these services, staff issued a Request for Proposals
(RFP). The RFP consisted of detailed specifications listing the work, equipment and materials needed to
help identify and pinpoint locations of water leaks in the City's potable water transmission and distribution
system.
The Acoustical Leak and Correlation Survey Service is one of the next steps in the Water Department's Five-
Year Water Loss Management Plan (City Secretary Contract No. 52427). The plan outlined a need for the
Department to proactively survey more of the distribution system on an annual recurring basis. A proactive
survey can save significant amounts of water and money, as many leaks in the system can take days,
weeks, or even months to surface. The Department has established a goal of completing 1,500 miles
(approximately 40\% of the system) of acoustical and correlation surveying to proactively identify and repair
leaks. In order to meet this goal, the Department plans on using the service to complete approximately half
of the surveying. The remaining half will be surveyed by in-house staff. Depending on the cost-effectiveness
of the contractor selected and the savings due to leaks proactively identified and repaired, the Department
may request an annual renewal of the service.
The RFP was advertised in the Fort Worth Star-Telegram on July 15, 2020, July 22, 2020, July 29, 2020,
August 5, 2020, and August 12, 2020. The City received seven bids. Proposals were scored based on the
consultants prior experience and references on similar projects with other water utilities, the proposed
schedule, work plan, equipment and value, specific qualifications of key personnel and the total cost of work
to be performed. Staff from the Water Department evaluated the proposals and recommends awarding a one
year agreement to Pure Technologies US Inc. d/b/a Wach Water Services. No guarantee was made that a
specific amount of these services will be purchased. The bid amount for the Water Department's
annual requirements is up to $144,364.00.
An administrative change order or increase may be made by the City Manager up to the amount allowed by
relevant law and the Fort Worth City code and does not require specific City Council approval as long as
sufficient funds have been appropriated.
A waiver of the goal for M/WBE subcontracting requirement is approved by the Office of Business Diversity,
in accordance with the M/WBE or BDE Ordinance, because the purchase of goods or services is from
sources where subcontracting or supplier opportunities are negligible.
FISCAL INFORMATION/CERTIFICATION:
The Director of Finance certifies that funds are available in the current operating budget, as previously
appropriated, in the Water& Sewer Fund to support the approval of the above recommendation and
execution of the service agreement. Prior to any expenditure being incurred, the Water Department has the
responsibility to validate the availability of funds.
