Electro Scan Inc. is a California-‐based high tech company engaged in designing and developing breakthrough technologies to automafcally idenffy and report water, sewer, and gas pipeline defects, without third party interpretafon or operator judgment.

Founded by soiware entrepreneur and water industry veteran, Chuck Hansen, Electro Scan’s technology is changing the way uflifes assess, priorifze, and cerffy new and rehabilitated pipes, oien providing informafon that conflicts or reverses condifon assessments that rely on acousfc (listening) or visual (seeing) defects.

Winner of WEF’s Best Innovafve Technology Award (2013) and named Best CleanTech Water & Wastewater Company by Brifsh-‐based New Economy Magazine, Electro Scan finds defects in water, sewer, gas pipes, undetected by legacy inspecfon techniques.

Findings and Conclusions


•  Electro Scan idenffied 11 Defects compared to Zero Defects found by CCTV. •  Total Defect Flow idenffied by Electro Scan is esfmated to be 0.92 l/s (79,748 l/d). •  The seven (7) highest defect flows found by Electro Scan contributed 0.88 l/s or 96% of defect flow. •  The Electro Scan survey took six minutes to complete, with a final report available in five minutes. •  CCTV Report by FM Conway does not indicate numerous defects shown on the CCTV Video,

including an Acfve Break-‐in Tap. •  Any use of past CCTV inspecfons as part of a Big Data analysis should be approached with caufon,

or risk inappropriate conclusions to determining CrifcalSewers.

Findings

Conclusions •  Electro Scan found numerous and significant defect flows not reported by the CCTV Report.

•  Had FM Conway adopted emerging U.S. sewer condifon assessment standards of Electro Scanning sewer lines, first, it could have had its CCTV operator use defect locafons established by Electro Scan to pan, flt, zoom, and capture detail images and assess the top seven (7) defect flows found by Electro Scan.

•  Given the proximity of the Electro Scan survey to major roadways (A118), this sewer has a high risk of flooding during either a severe or prolonged wet weather event.

•  FM Conway would gain a major compeffve advantage over its Compeftors (i.e. CCTV Only Contractors) by complefng Electro Scan surveys before all CCTV inspecfons.

It should be noted that if contractors are only allowed to visit a site once, then they could Electro Scan each Sewer, first, then review Electro Scan’s internafonal patent-‐pending reporfng to instruct the CCTV contractor which key defects to evaluate. Otherwise, the Contractor risks incorrectly assessing the sewer main by only using CCTV, and further risks client assets by missing large defect flows that may be suscepfble to flooding & infiltrafon.

Electro Scan Sewers To Measure Defect Flows, By LocaAon, Then CCTV Worst





CCTV is no longer recommended as the singular tool to assess sewers due to inherent problems to determine its water fghtness or priorifse defects for pre-‐ and post-‐rehabilitafon.

The Dirty Dozen

The Twelve Dirty Secrets of CCTV Inspecfon.

*

* -‐ 22 -‐ © Electro Scan Inc. 2015

1. CCTV Inspecfon Is a Dry Weather Assessment Tool -‐-‐ Not Well Suited in Assessing Wet Weather Events.


2. CCTV surveys must have an empty pipe.


3.  CCTV cannot judge pipe wall integrity if too much grease i.e.

Any WRc/PACP Call Outs for ‘Grease’ typically miss poten6al defects.


4. CCTV surveys tend to rate ‘Roots’ but not leakage potenfal.


5. CCTV Surveys Rate Evidence of Encrustafons, but Not Defects.

In several EPA-‐funded projects pipes were found to ‘PASS’ water pressure tests, but had High Rates of Encrustafon, i.e. Entrustafons may give a False Posifve, while Electro Scan located and measured potenfal defect flow rates. EncrustaAon is (STILL) not an approved method of rehabilitaAon!


5. CCTV operators oien use different codes for same defect.

8. CCTV operators cannot rate, what they cannot see.

9. Silt may prevent CCTV Operator from seeing boKom of pipe.


10. Mulfple CCTV reports on the same pipe lack repeatability.

12. Cleaning a line oien removes tell-‐tale signs of defects.


B. How Does It Work? Electro Scan is designed to automafcally assess non-‐conducfve pipes (e.g. asbestos concrete, brick, clay, cement, plasfc, 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 uflizes a low voltage/high frequency patent-‐pending process to automafcally find & measure defects not commonly detected by closed-‐circuit television (CCTV) cameras or acousfcal devices. Using its internafonal patent-‐pending technology that measures the variafon of electrical current inside pipes, Electro Scan automafcally locates and measures potenfal leaks in GPM.

A. What Does Electro Scan Do, That CCTV Cannot? Answer: Find sources of infiltrafon and cracks. Infiltrafon is a key factor causing Sanitary Sewer Overflows (SSOs) and Combined Sewer Overflows (CSO) caused by cracks & defects found in manholes, sewer mains, service connecfons, and laterals. Given the limitafon of CCTV – i.e. not able to visually find leaks -‐-‐ Electro Scan automafcally finds , locates, and measures the amount of infiltrafon (i.e. in gallons per minute) caused by defects. Electro Scan can also cerffy 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 locafon and quanfficafon 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 CommiKee F36. Winning internafonal 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 generafon in defect locafon and cerfficafon of pipeline repairs & rehabilitafon, able to work in wet weather and dry weather condifons.

While ‘Large Current Readings over a Large Area’ oien result in the largest esfmated l/s or Defect Flow, frequently the largest esfmated l/s may be caused by smaller current readings over larger areas (Right). From 12,000 – 20,000 data points may be collected for an average 100m sewer main with Electro Scan represenfng the first automated tool to idenffy & measure leaks to the closest 1 cenfmeter 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 Crifcal Sewers® cloud applicafon providing an esfmated Liters per Second (Defect Flow) based on the Defect Area and Electric Current sustained over that Area.

About Chuck Hansen Chuck Hansen, age 59, is a Public Works and IT veteran, implemenfng some of the largest Asset Management, Building Permit, and Uflity Billing applicafons for over 1,000 water, sewer, roadway, and railway clients throughout the world. When Chuck sold his soiware company in 2007, cumulafve Hansen client databases held over 1 million closed-‐circuit television (CCTV) inspecfon reports, including over 6 million pipeline defects. In 1990, working with the City of Houston Wasteload Control Branch, Chuck co-‐developed the first nafonal CCTV standard, used by +250 TV inspecfon trucks to conduct a comprehensive crifcal sewers database in response to a Region VI EPA consent decree. Chuck spearheaded development of the first asset-‐specific accounfng system in response to new internafonal financial standards in Australia and New Zealand, adopted by all local councils and uflifes in New Zealand. Later, he led his internafonal soiware programming team to design, development, and deploy, integrated customer service, billing, building permit, and property tax accounfng systems. Partnering with San Francisco-‐based private equity firm Golden Gate Capital, Chuck doubled the size of his company over two-‐years through acquisifons, new web-‐based products, and internafonal expansion, exifng 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.
