any negligent errors, omissions or other deficiencies in its plans, designs, drawings,
specifications, reports and other services required. The PROVIDER shall perform its
services to conform to generally-accepted professional standards and the requirements
of the CITY.

PROVIDER of responsibility for the technical accuracy and adequacy of its services.
Except as otherwise provided in this Agreement, neither the CITY'S review, approval, or
acceptance of, nor payment for, any of the services shall be construed to operate as a
waiver of any rights under this Agreement or of any cause of action arising out of the
performance of this Agreement to the full extent of the law.
7. INDEMNIFICATION/HOLD HARMLESS.
The PROVIDER shall defend, indemnify and hold the CITY, its officers, officials,

or suits, including attorney fees, arising out of or resulting from the acts, errors or
omissions of the PROVIDER in performance of this Agreement, except for injuries or
damages caused by the sole negligence of the CITY.
Should a court of competent jurisdiction determine that this Agreement is subject to
RCW 4.24.115, then, in the event of liability for damages arising out of bodily injury to
persons or damages to property caused by or resulting from the concurrent negligence
of the PROVIDER and the City, its officers, officials, employees, and volunteers, the

insurance against claims for injuries to persons or damage to property that may arise
from or in connection with the performance of the work hereunder by the PROVIDER,
its agents, representatives, or employees.

4.TECHNICAL REQUIREMENTS,SPECIFICATIONS,AND CONSTRAINTS
This section outlines certain limitations of the technology as well as requirements of The City of Auburn,WA.
4.1 OPERATIONAL REQUIREMENTS
4.1.1 Owner will supply a crew for operation of their apparatus.Echologics is not responsible for their operation or
modification.
4.1.2 Valve boxes and pothole excavations used as test sites should be cleaned out prior to survey. Hydrants used as test
sites must not be leaking.If cleaning cannot be performed prior to site-work,on site cleaning must be arranged by
Client on request.
4.1.3 Client will provide traffic management(including manpower and equipment)as and when required.Echologics is not
responsible for any traffic control requirements,unless explicitly included in this proposal.Client will secure required
permits,and be familiar with local laws and regulations.
4.1.4 If indicated as a requirement by Client,Echologics will supply one crew member trained as a confined space entrant.
All other aspects of confined space entry will be of the responsibility of Client,unless explicitly included in this
proposal.
4.1.5 Fall protection,including supply of fall prevention equipment and harnesses,will be of the responsibility of Client.
4.1.6 Echologics will follow any addition safety procedures specified by Client.
4.1.7 All available information regarding the pipes to be tested should be provided to Echologics in advance to assist with
survey planning.This includes as-built drawings,presence and locations of repair segments,nominal pipe information,
GIS information,and pressure and flow information.
4.1.8 If De-chlorination/Chlorination and/or backflow preventers are required,these will be the responsibility of Client.
4.2 GENERAL TECHNICAL SPECIFICATIONS AND CONSTRAINTS
4.2.1 Fluid temperature must be between 33 degrees and 100 degrees Fahrenheit(0.5 degrees and 38 degrees Celsius).
4.2.2 Liquid flow velocities above 5 feet/second(1.5 meters/second)may result in turbulence in the line, introducing noise
which can reduce the sensitivity of leak detection,and prevent ePulse testing. Echologics recommends that Client
take steps to ensure velocities are below these levels,but will conduct testing nonetheless if Client elects to leave
them at higher levels.
4.2.3 Operating pressure from 15 to 150 psi(1 to 10 bar)are standard.Pressures outside of this range require special
consideration. •
4.2.4 Large air or gas pockets present in the pipe interfere with Echologics'testing.Purging air prior to testing is
recommended.
4.2.5 Significant amounts of dispersed air(milky water)can skew results.Purging of dispersed air may be required.
4.2.6 All forms of non-destructive testing involve an inherent and unavoidable level of uncertainty.The results provided by
Echologics are not guaranteed.The methods used for leak detection and condition assessment are highly dependent
on input parameters therefore it is not possible to certify the results.Echologics is not responsible any actions taken or
recommendations made by Client based on the results of the report.

4.3 ECHOWAVETM'TECHNICAL SPECIFICATIONS AND CONSTRAINTS
4.3.1 For surface mounted sensors, recommended sensor-to-sensor spacing is 300 to 900 ft(100 to 300 m); max is 1500
feet(500 m).
4.3.2 For surface mounted sensors,vertical access is required to lower sensors from the surface.Angled/bent access is not
suitable.
4.3.3 Surface mounted sensor connections point must be free of dirt and debris and in good working order.
4.3.4 For hydrophone sensors, recommended sensor-to-sensor spacing is 1000 to 3000 ft(300 to 1000 m); max is 5000
feet(1500 m).
4.3.5 Hydrophone sensors require a 1.5 inch NPT female connection with an isolation valve.
4.3.6 Leak locations are generally+/- 10 feet(3 m); accuracy depends on sensor spacing, pipe material consistency, and
accuracy of information provided.
4.3.7 Minimum detectable leak sizes generally range from 0.5 gal/min(2 I/min)to 5 gal/min(20 I/min),depending on
pipe diameter and material,sensor spacing,and the presence of external or internal noise sources.
4.4 EPULSETM'TECHNICAL SPECIFICATIONS AND CONSTRAINTS
4.4.1 Acceptable pipe materials are:Cast Iron,Steel,Ductile Iron,Asbestos Cement,and to a limited extent Reinforced
Concrete.
4.4.2 Concrete,Mortar and Bitumen linings are acceptable. Lining thickness should be specified by Client for use in
calculations.
4.4.3 Diameters may range from 1 to 60 inches(25 to 1,525 mm).Larger mains are possible but special consideration
must be taken.
4.4.4 Testing pipes with diameter:wall thickness rate exceeding 30:1 will result in higher margins of error,and is not
recommended.
4.4.5 For surface mounted sensors,recommended sensor-to-sensor spacing is 300 to 650 ft(100 to 200 m);longer
distances may not yield results.
4.4.6 For surface mounted sensors,vertical access is required to lower sensors from the surface.Angled/bent access is
not suitable.
4.4.7 Surface mounted sensor connections point must be free of dirt and debris and in good working order.
4.4.8 Hydrophone sensors require a 1.5 inch NPT female connection with an isolation valve.
4.4.9 Accurate temperature and pressure values are required.Allowing measurement during the testing is recommended.
4.4.10 Performance specifications are based on a sensor spacing of 330 feet(100 m),and accurate pipe information.
4.4.11 Accuracy of average pipe wall thickness or stiffness calculations varies depending on many factors,including the.
consistency of the pipe materials,accuracy of the design information provided,accuracy of the pipe alignment
information provided,consistency of the fluid's bulk modulus,consistency of the fluid's temperature,and the
presence of PVC repair sections. In most cases,accuracies will generally fall within the following ranges:
• Cast iron&asbestos cement mains,average minimum pipe wall thickness+/-10%of the original nominal
thickness.
• Ductile iron&steel mains,average minimum pipe wall thickness+/-15%of the original nominal thickness.
• Reinforced concrete mains,average hoop stiffness+/-7200 kilo-pound per square inch(50 gigapascal).

• A calibration test is recommended for the first test in a given water supply.This test requires a single ePulse
measurement on a newer ductile iron pipe of known condition containing water from the same supply as the mains
being inspected.
• For liquids other than potable or raw water,error margins are substantially higher,and are generally provided as a
percentage of the pipe segment in the best condition rather than an actual wall thickness or wall stiffness
measurement.
