Top 10 Things To Know About Electro Scan

1. What is Electro Scan? 2. What Does It Tell Me (That We Don’t Already Know)? 3. How Does It Work In The Field 4. What Are The Key Components of Electro Scan? 5. How Does It Calculate GPM for Each Defect? 6. How is My Data Managed? 7. What Industry Standard Covers Electro Scan? 8. What Textbooks or Manuals? 9. Who is Backing Electro Scan? 10. What Major Awards Has Electro Scan Won?

B. How Does It Work? Electro Scan is designed to automatically assess

non-conductive pipes (e.g. asbestos concrete, brick, clay, cement, plastic, reinforced concrete, etc.), where no electrical current should ever be able to “leak” or escape into the ground from inside the pipe – unless, of course, there is a crack or break in a pipe. Electro Scan’s technology utilizes a low voltage/high frequency patent-pending process to automatically find & measure defects not commonly detected by closed-circuit television (CCTV) cameras or acoustical devices. Using its international patent-pending technology that measures the variation of electrical current inside pipes, Electro Scan automatically locates and measures potential leaks in gallons per minute.

A. What Does Electro Scan Do, That CCTV Cannot? Answer: Find sources of

infiltration and cracks. Infiltration is a key factor causing Sanitary Sewer Overflows (SSOs) and Combined Sewer Overflows (CSO) caused by cracks & defects found in manholes, sewer mains, service connections, and laterals. Given the limitation of CCTV – i.e. not able to visually find leaks -- Electro Scan automatically finds , locates, and measures (i.e. in gallons per minute) the amount of infiltration (i.e. in gallons per minute) caused by defects. Electro Scan can also certify newly installed, recently repaired and rehabilitated pipe lining.

C. Who Has Endorsed or Used Electro Scan? Electro Scan has

undergone numerous U.S. EPA studies and found superior to CCTV in finding the location and quantification of defects that cause leaks. Electro Scan is the only company with products in compliance with ASTM Standard F2550-13, just approved for another five years by ASTM Committee F36. Winning international acceptance, Electro Scan has recorded nearly 1 million feet of scans in the U.S., England, Japan, Australia, and New Zealand, and represents the next generation in defect location and certification of pipeline repairs & rehabilitation, able to work in wet weather and dry weather conditions.

While ‘Large Current Readings over a Large Area’ often result in the largest estimated GPM or Defect Flow, frequently the largest estimated GPMs may be caused by smaller current readings over larger areas (Right). From 12,000 – 20,000 data points may be collected for an average 300 ft sewer main with Electro Scan representing the first automated tool to identify & measure leaks to the closed 1 centimeter or 0.4 inch.

Electro Scan’s standard Graph displays the Maximum Defect Current and Lengths (i.e. from and to start and end points of defects), with its Critical Sewers® cloud application providing an estimated Gallon per Minute (Defect Flow) based on the Defect Area and Electric Current sustained over that Area.

About Chuck Hansen Chuck Hansen, age 57, is a Public Works and IT veteran, implementing some of the largest Asset Management, Building Permit, and Utility Billing applications for over 1,000 water, sewer, roadway, and railway clients throughout the world. When Chuck sold his software company in 2007, cumulative Hansen client databases held over 1 million closed-circuit television (CCTV) inspection reports, including over 6 million pipeline defects. In 1990, working with the City of Houston Wasteload Control Branch, Chuck co-developed the first national CCTV standard, used by +250 TV inspection trucks to conduct a comprehensive critical sewers database in response to a Region VI EPA consent decree. Chuck spearheaded development of the first asset-specific accounting system in response to new international financial standards in Australia and New Zealand, adopted by all local councils and utilities in New Zealand. Later, he led his international software programming team to design, development, and deploy, integrated customer service, billing, building permit, and property tax accounting systems. Partnering with San Francisco-based private equity firm Golden Gate Capital, Chuck doubled the size of his company over two-years through acquisitions, new web-based products, and international expansion, exiting the business he started with his father and older brother in 2007.

Chuck lives in Sacramento, California with his wife, Deborah, a civil engineer, his three daughters and grown son, nearby.

MH 3569 – MH 3563 Summary

59

3

• Electro Scan identified 96 locations of potential infiltration throughout the 737 feet length of the three (3) pipes • Total Estimated Leakage of the three (3) pipes inspected represents 77.81 gallons per minute, or over 112,046 GPD, ±40%

accuracy, assuming a 1 foot head and 1% or less pipe slope.

• Average estimated flow thru each defect is 0.81 gallons per minute (1,166 GPD), occurring approximately every 7.6 feet. • The CCTV inspection identified only thirty-three (33) defects within the 737 feet of pipe that could have potentially

contributed to infiltration. Although the inspections were not performed with PACP standards, they did address most of the visual problems. While a few leaks were “visible” during the time of inspection, some locations were identified with “infiltration” when there was no active infiltration present. This situation presented itself mostly in the 3569 – 3563 pipe.

• While these defects are definitely concerns, they were far from being the worst infiltrating defects within the pipe.

The quantity of potential infiltration on these particular pipes should serve as an example of how Electro Scan is able to objectively locate and measure defects to help make better rehabilitation decisions. Quantitative data, like the data provided by Electro Scan, should be used to either determine the most efficient and cost-effective rehabilitation method or to determine which pipes warrant further investigation and inspection. Often times, Electro Scan can identify certain locations or lengths in the pipe that are significantly worse than the rest of the pipe. In cases such as that, rehabilitation methods such as spot repairs can be considered. These pipes have defects spread throughout their entire length, at almost every other joint, indicating that whatever rehabilitation method that is chosen should include the entire pipe. However, it would have to be compared, quantitatively, to the rest of the pipes in the system to determine its priority in a rehab plan. By utilizing all technologies available, rehabilitation budgets can be maximized, and infiltration removed from the system most effectively. As mentioned during the demonstration, in addition to helping to prioritize rehabilitation plans, Electro Scan is able (per ASTM 2550-13) to certify new construction and rehabilitation. With these pipes being scheduled to possibly be lined with a cured-in-place pipelining method, it is recommended that post-lining certification be completed using Electro Scan.

60

Findings and Conclusions

• Identify and measure all sources of infiltration from cracks, bad joints, and defective service connections,

• Rank & prioritize sewer mains and laterals that should be repaired, relined, or renewed,

• Integrate with hydraulic modeling programs to re-calibrate model assumptions based on its estimated gallons per minute (GPM) of flow from defects,

• Certify point repairs, relining, and new construction (i.e. citing ASTM F2550 as part of any published work specification) to ensure that projects performed by third-party contractors are delivered without defects or leaks, prior to Acceptance.

As demonstrated during the presentations in Carmel, IN, Electro Scan does not replace CCTV; however, it does confirm the limited use of television inspection. While visual inspection, aided by pan & tilt and 360o panorama capabilities, is recommended to identify alignment problems, cross bores, sags, fats, oils and grease, construction debris, and protruding service connections, television inspection is not recommended to identify sources of infiltration or exfiltration or as final Acceptance of point repairs, relining, or new construction projects.

Recommended use of Electro Scan include the ability to:

Originally approved in 2006, ASTM F2550 was recently

modified to expand its use to include ‘testing and

certification of pipe repairs, renewal, and new

construction.’ The revised standard was approved

October 1, 2013, by unanimous vote of Committee F36, for

renewal for a five-year extension.
