RE: In-Service Treated Water Leak Detection and Mapping of Laguna Madre and Port Aransas
Pipelines
Dear Mikail,
Pure Technologies U.S. Inc., a Xylem brand is pleased to offer our services to Corpus Christi Water
(CCW)for inline leak and air pocket detection, as well as mapping of the Laguna Madre Crossing
and Port Aransas pipelines.
The Laguna Madre Crossing Pipeline consists of an inspection distance of roughly 21,940 LF (4.15
mi) of 24-inch Asbestos Cement pipe (ACP). The Port Aransas Pipeline consists of an approximate
inspection distance of 37,291 LF (7 mi) of 20- and 16-inch ACP and Flexible Polyvinyl Chloride
(FPVC).
Between the two pipelines an approximate total of 59,231 LF (11.2 miles) of pipeline is accounted
for in this project scope. We propose using our SmartBall® free-swimming inspection platform to
complete this project. SmartBall inspects pipelines while they are in service, detects acoustic activity
associated with leaks and trapped air pockets, and uses motion data to map the pipelines' true
alignment. Features that make Pure Technologies' SmartBall platform the ideal solution for this
project include:
• Reporting the location of leaks and air pockets within ±6 feet of their actual location
• The ability to live track and locate the actual position of the SmartBall tool within the
pipeline
• The ability to map the true X-Y pipeline alignment using field-collected GPS points
combined with SmartBall motion data
• 24-hour preliminary analysis to identify and investigate medium and large leaks prior to
demobilizing
• 15+ years of experience successfully inspecting over 8,350 miles and reporting over
3,800 leaks
Figure 1 below shows the two pipelines mentioned above and their general limits of assessments.

SmartBall
The SmartBall inspection platform is a free-swimming, nondestructive inline inspection technology
that detects acoustic activity associated with leaks and pockets of trapped air in pressurized
pipelines. Optionally, SmartBall can map the pipeline using the motion data of the tool along with
field-collected GPS data.
The SmartBall tool is typically inserted through a valve into an active line. Once deployed, the tool is
propelled by the hydraulic flow and can navigate inline valves, 90-degree bends, tees, diameter
changes, profile changes, and vertical risers. It is typically extracted by inserting an expandable
retrieval net through a pressurized stack attached to a 4-inch full-bore flanged valve.
The SmartBall tool is continuously tracked during an inspection using proprietary tracking devices
synchronized with the tool and tracking sensors installed along the pipeline prior to deployment.
When mapping of the pipeline is included in the project scope, advanced location algorithms are
used to evaluate motion data recorded by the SmartBall tool in combination with field-collected GPS
data to determine the alignment of the pipeline.
An overview of the SmartBall platform inspection process is shown in Figure 4.
Transient Pressure Monitoring
A hydraulic evaluation is proposed in order to understand the operational and surge pressures
within the pipeline. When pipe wall degradation is combined with surge pressures, the likelihood of
pipe failure can be significantly increased. Evaluation of the pump station operation, such as pump
startup mode, typical and peak flows, operating and surge pressures, and surge protection, can
provide important information on the stresses imparted on the pipeline.

TECMN

Hydraulic pressure transients (also known as surges or water hammers) occur in pipelines when the
pressure conditions in the system change due to variances in pressure or flow(e.g. pump on/off
cycles or the rapid closure of a valve). The magnitude of a transient is related to several factors that
include, but are not limited to, the flow rate within the pipeline, the time in which the change in
steady-state condition occurs, and a pipe's hoop stiffness. During a transient event, the kinetic
energy within the pipeline (velocity of the water), is converted into potential energy(pressure in the
pipe) and strain energy(deformation/strain in the pipe wall) by the propagation of transient pressure
waves. A transient pressure wave can travel through the pipeline at speeds greater than 3,000 feet
per second and can cause damaging pressure events and vacuum conditions, which can lead to
permanent damage within the pipe wall and failure within the pipe system.

Conventional pressure monitors collect data in intervals of seconds or minutes while transients may
occur in fractions of a second and may be missed by traditional equipment. A transient pressure
monitor continuously samples pressure at a high rate and records data every few minutes under
normal operating conditions; however, when a transient pressure event is detected in the pipeline,
the sampling rate increases to once every 50 milliseconds (20 readings per second). Telog pressure
monitors are also capable of recording negative pressures in a pipeline as low as-14.7 psi, or
perfect vacuum, as well as positive pressures in the pipelines as high as 300 psi.

Project Milestones and Deliverables
Additional details regarding insertion, extraction and tracking of the inspection tools are provided in
Appendix A, Inspection Considerations.
Planning and Mobilization
The planning process is an integral element of a successful project. It allows the team to identify
features of the site or the pipe that could prevent a successful inspection. Actions can then be
implemented to mitigate any potential risk.
Pure Technologies will meet with CCW to perform a site visit to assess access to the pipeline and
identify potential challenges and risks. As much information as possible on the pipeline will be
requested during the planning process. It is our understanding that CCW will facilitate all civil activity
for pipeline access and tracking sensor installation, which may require modification to existing
features, excavation, tapping, traffic control, scaffolding and other activities identified during the
planning process necessary to access pipeline features determined to be critical to the inspection.
Pure Technologies will make every effort to utilize existing pipeline features where feasible.
Activities undertaken as part of the planning and mobilization process include, but are not
necessarily limited to the following:
Project document review
• Project planning site visit and review
• Pre-inspection coordination/meetings
• Planning document development, including tracking plan and tracking sensor installation
details
Equipment and staffing logistics
Tool preparation
Pre-inspection activities required in advance of the scheduled inspection date
Based on the information gathered from the project planning site visit and all available documents, a
detailed Project Planning Document(PPD) outlining the inspection plan, including insertion and
extraction procedures and tracking sensor locations will be submitted prior to commencing the
work. The PPD will be submitted to CCW in electronic PDF format at least two weeks prior to the
inspection, dependent on the receipt of project data, or as soon as possible in cases of urgent
mobilization. CCW should review and provide comments or approval of the PPD prior to
mobilization. Any changes to the scope that arise in the planning process which impact the pricing in
this proposal will be discussed with City and mutually agreed upon before proceeding.
During the site visit, GPS location data will be collected for all Control Points and Reference Points.
Chambers and vaults must be opened to ensure that the GPS points are recorded above the actual
pipeline feature or to add an offset to the GPS points.

Planning and Mobilization Deliverables
1. Project Planning Document that outlines the inspection plan, including insertion and
extraction procedures and tracking sensor locations.
Inspection
SmartBall tracking sensor installation will be completed the day prior to inspection and may take one
to two days, depending on sensor locations and accessibility. It is expected that CCW will aid with
any sensor installations that require soft digs or pavement coring to access the pipeline and will
provide appropriate traffic control during tracking installations, if required, as outlined in the PPD.
Leak locations are determined using data recorded by the sensors onboard the SmartBall tool as
well as that recorded by the tracking devices. This data is also used to determine if a leak is
occurring on a pipe joint, barrel, or pipeline feature. Leaks occurring on the barrel of a pipe may
indicate the pipe has been structurally weakened and is in danger of failing. Experience has shown
our analysis methods are accurate to within approximately ±6 feet.
The inspection is anticipated to take two days to complete. Immediately preceding the deployment
of the SmartBall tool, Pure Technologies personnel will measure the flow speed, flow direction, and
pipeline operating pressure to verify the conditions in the pipeline. Several tracking teams will be
assigned to monitor the tool's movement through the pipeline. If required, CCW will provide traffic
control during the inspection at each tracking sensor location. Coordination with operations staff will
be required throughout the duration of the inspection, particularly for activities such as valve
operation, pump management, etc. These activities will be outlined in the PPD. Upon completion of
the inspection, data will be downloaded from the SmartBall tool and shared with the Pure
Technologies analysis team.
Prior to demobilizing from the inspection, the Pure Technologies team will review data recorded by
the SmartBall tool and investigate suspected medium and large leaks identified during the
inspection. The results from this analysis will be communicated directly to CCW through email,
phone, or in-person. To investigate, personnel will travel to the location of the suspected leak to look
for obvious signs of leakage, listen with a ground microphone, investigate nearby pipeline features
and manholes, and will record additional GPS points used to improve the final reported location of
the leak that will be delivered in the draft report.
Further details on considerations related to the pipeline inspection such as pressure, flow
requirements, or insertion/extraction requirements can be found in Appendix A, Inspection
Considerations.
The SmartBall tool will be inserted into the pipeline a second time to acquire the data needed to
map the pipeline alignment. The pipeline alignment will be determined using motion data collected
during inspection runs, as well as advanced algorithms.
Optional Inspection Services
Flow Rate Verification. Onsite verification of flow rates under inspection conditions can be

pipeline networks that require numerous valves to be operated or for utilities needing additional
assistance to verify that operating conditions in the pipeline are suitable for inline inspection.
Data Analysis
The Pure Technologies analysis team will analyze the data collected by the SmartBall platform to
document details of acoustic events including acoustic intensity plots and tracking details. A dig
sheet will be developed for each leak to aid in location and excavation. Dig sheets include an aerial
view of the pipeline alignment and detail a leak location based on the distance from the leak to the
nearest upstream and downstream pipeline features.
For pipeline mapping data analysts will use the SmartBall directional data, along with field collected
GPS points and pipeline bearing information, to create a geodatabase that characterizes the true
alignment of the pipeline. This alignment is then compared to available pipeline information, such as
an existing pipeline GIS and as built drawings, to identify conflicts or confirm the assumed pipeline
alignment. In areas where the SmartBall-derived alignment agrees with a utility's records, the utility
can feel more confident the assumed location of the pipeline is close to actual. If a conflict is
identified, a targeted effort of exposing the pipeline, line finding and/or surveying at these specific
areas may be warranted depending on the location accuracy required for the subject pipeline.
The error range of the mapping results will be calculated considering the distance between control
points, availability of GPS points and pipeline heading, and quality of rolling motion of the SmartBall
tool.

Pipeline and Inspection Details
Pure has been given the drawings and schematics of both the Laguna Madre Crossing and Port
Aransas pipelines for an initial review. During this review, it is apparent that to carry out a full
assessment of these pipelines, that some pre-inspection modifications to them will be necessary.
Laguna Madre Crossing
The Laguna Madre Crossing begins on the northern side of the channel near the intersection of
Laguna Shores Road and Lola Johnson Road. Based on the schematics the pipeline begins as 24-
inch steel (STL)within a gate valve chamber and continues southeast toward the Sand Dollar Pump
station on South Padre Island. Along this path of approximately 4.15 miles, at least three (3) gate
valves are shown within the drawings which can be used as sufficient tool tracking locations for the
inspection(s).
To insert and extract SmartBall into and out of the pipeline, modifications to the pipeline will be
needed. To insert and extract the SmartBall tool, a minimum 6-inch top outlet will need to be
installed.
Port Aransas
The Port Aransas pipeline begins south of the Sand Dollar Pump station near the intersection of
HWY 361 and Park Road 22. The pipeline continues in a northeast direction and feeds the
communities of Mustang Island. An initial review of the drawings indicates that there are no direct
access points to the pipeline for either insertion and extraction nor for tool tracking purposes. To
that end, new 6-inch top outlet access points are required at each end. In addition, various potholes
will need to be added along the length of the pipeline to be used as tool tracking and to increase
location accuracy of reported leaks/air pockets.
Additional Work (New Access Taps)
Knowing that conducting these inspections will require some modifications to the pipeline, Pure has
reached out to a well-known pipe tapping company(Rangeline Group)who specialize in large
diameter wet tapping services throughout the US. The required new access taps include four(4) 6-
7
TECH

inch wet-taps to be placed (two for each pipeline- insertion and extraction). Pricing for this work is
reflected within the Fee Table as well, includes a 15% subcontractor management fee.
CCW Responsibilities
It is expected that the activities listed below will be completed by CCW. Requirements will be
determined in more detail during the inspection planning process.
® Provide information about the pipeline at least four weeks prior to the inspection date
including, but not limited to, plan and profile drawings, lay sheets, shop drawings,
manufacturing details, and details of access structures and appurtenances- if available.
• Obtain any required legal right-of-entry on the property.
• Provide support personnel during the inspection for locating the access structures, traffic
control, valve operation, pump operation, and other support as necessary.
• Provide Pure Technologies with the typical flow velocities and pressures for pipeline
operation, and the expected minimum and maximum values for each. If this data is
unavailable, Pure Technologies would like the opportunity to verify flow velocities
recommended prior to performing the inspection.
• Provide and maintain safe and reasonable access to all work sites throughout the
inspection and obtain permits as required.
• Render confined areas safe for the services, including lockout/tagout of pumps, valves
and motors; dewatering chambers and vaults to permit movement of persons and
equipment; and vector and rodent control as necessary.
• Provide scaffolding to support SmartBall insertion or extraction if needed.
• Excavate, dewater, shore up, and/or provide scaffolding of job area and other civil activity
as necessary in compliance with Occupational Safety and Health Administration and local
standards and regulations.
• Operate the pipeline in a manner that will achieve the minimum required flow velocity
indicated in the Planning Document throughout the inspection.

If additional work is required due to circumstances outside of Pure Technologies' control
or based on additional requests from CCW, a mutually agreed change order will be
required.
An allowance for unforeseen expenditures is assumed due to various unknowns at this
time. Should unforeseen expenditures arise, a mutually agreed upon solution will be
made between Pure and CCW on how/where to spend these funds.
A penalty charge of$5,665.00 may apply should the work be delayed by CCW within two
weeks prior to agreed mobilization date. A project delayed into the next calendar year
may incur a price increase in the amount of the local Consumer Price Index. If deemed
necessary, this penalty charge would be billed to Item 17 (Allowance for unforeseen
expenditures).
A penalty charge of$11,330.00 may apply should the work be cancelled by CCW within
two weeks prior to agreed mobilization date. Any other charges incurred prior to the
cancellation scenario shall be invoiced in full. If deemed necessary, this penalty charge
would be billed to Item 3 (Mobilization).
Upon a mutual agreement between Pure and CCW, a stand-by charge of$10,815.00 per
crew day may apply if the project is delayed for 24 hours or more by CCW after
mobilization. Circumstances outside the control of CCW would not result in a stand-by
charge.

Appendix A: SmartBall Inspection Considerations
Pipeline Pressure
Inline leak detection technology is inherently more sensitive than external methods and correlators
because it brings the acoustic sensor within one pipe diameter of the leak. Acoustic leak detection
functions by detecting the acoustic signature generated by the sudden drop in pressure of water
exiting the pipeline at the site of a leak. SmartBall technology requires a minimum pressure
differential between internal and external pipeline conditions of 15 psi (1 bar)for acoustic leak
detection. For pipelines in high water tables or river crossings, the resultant hydrostatic head acting
against the exterior of the pipe wall must be taken into consideration.
During the SmartBall inspection, CCW staff will need to operate the system to maintain pipeline
pressures as necessary to accommodate the needs of its customers. A review of the pipeline will be
performed as part of the planning process to identify potential areas where the pressure may drop
below the minimum required pressure differential for acoustic leak detection. Additional factors that
affect acoustic leak detection include tunnels and encasements where the sudden drop in pressure
that causes the acoustic signature generated by the leak may not occur at the site of the leak inside
the pipeline, but rather at the point where the fluid exits the tunnel or encasement if the 'leak path'
becomes pressurized between the pipe wall and the tunnel or encasement. Approximate pressure
measurements may be requested prior to and/or during the inspection to ensure the pipeline is
operating within expected conditions.
Insertion and Extraction Requirements
The SmartBall tool is typically inserted through a 4-inch (100mm) or larger full-bore flanged valve
into an active pipeline. When using standard insertion equipment, the valve should have direct
access to the pipeline with no bends in the connecting riser. The minimum internal diameter of valve
opening and pipeline access must be no less than 3.75 inches (95.3mm). A minimum of 4 feet(1.3m)
of overhead clearance is required above the flange of the insertion valve. Alternative methods for
insertion include utilizing check valves in pump stations, areas where the pipeline transitions to
gravity, or pumping the SmartBall through offset piping such as a hydrant or bypass.
If a hot tap is being performed to add an access point, the drill bit must be at least 3.75 inches
(95.3mm) in diameter and centered within the newly installed valve. Note that a 4-inch valve on an
access point installed with a drill bit smaller than 3.75 inches will not provide the clearance needed.
The SmartBall tool is typically extracted from the pipeline by installing a pressurized stack on a 4-inch
(100mm)full bore flanged valve, or larger, with a minimum internal diameter no less than 3.75
inches(95.3mm). The valve should be on the crown of the pipe and be located on a flat section of
pipeline with no vertical slopes or horizontal bends 30 feet(9m) upstream of the valve. A minimum
of 16 feet(5m) of overhead clearance is required above the flange of the extraction valve. It is
possible to core the roof of a vault above the valve with a 6-inch (150mm) or greater opening if the
vault does not have enough overhead clearance. The extraction net utilizes a tracking sensor and a
camera to confirm the SmartBall tool has been caught. Other extraction methods, such as retrieval
from a reservoir using a remotely operated vehicle, are possible and can be evaluated by the
SmartBall technical experts for feasibility.
18
TECH
a xylem brand
Tracking
Prior to the inspection, tracking sensors will be installed along the pipeline to track the position of
the SmartBall tool. The tracking sensors function best when installed as close as possible to the
water column in the pipeline and are attached to metal surfaces of pipeline appurtenances, such as
air release valves, flanges, valves, or any other contact point on the pipeline. At these locations, Pure
Technologies staff clean an area of the pipe approximately 3 inches by 3 inches (75mm by 75mm)
and will adhere tracking sensors using a fast-drying epoxy. Computers synchronized with the
SmartBall tool will be connected to the tracking sensors to calculate the location and velocity of the
SmartBall tool as it approaches and passes the tracking location. Tracking teams will set up at
tracking sensors before deploying the SmartBall tool and will 'leap-frog'to subsequent tracking
locations as the SmartBall tool traverses the pipeline on its way to the extraction point. A tracking
plan and details for installing tracking sensors will be included in the PPD submitted to CCW prior to
the inspection.
Flow Requirements
The SmartBall tool requires a fluid velocity of 0.5 feet per second (0.15 meters per second)to
traverse flat sections of pipeline. The ideal fluid velocity for most pipelines is 2 to 4 feet per second
(0.6 to 1.2 meters per second)for traversing slopes and allowing tracking teams to relocate to the
next tracking location. The maximum fluid velocity before data quality is impacted is 6 feet per
second (1.8 meters per second)for leak and air pocket inspection and 3 feet per second (0.9 meters
per second)for SmartBall mapping. The SmartBall tool usually travels at approximately 70% of
average fluid velocity. CCW staff will control the flow rate to confirm the requisite velocity during tool
deployment as defined in the PPD. Pure Technologies will also evaluate pumping rates and cycle
times to determine if supplemental water will be required to complete the inspection. It should be
noted that air pocket and leak detection surveys should be performed as close to typical operating
conditions as feasible.
Live Pipeline Inspection Risks
Despite meticulous planning and preparation, live pipeline inspection carries an inherent risk that
cannot be avoided. There is a possibility that the inspection platform could encounter problems
during the inspection run that could lead to loss of data, requiring a re-inspection or at worst the tool
getting stuck in the pipeline due to unforeseen or unknown obstructions. The planning process is
used to mitigate any potential risks.
