Important Updates Alter Sewer Main Condition Assessment and Recommends New Standards for Accepting Post-Rehabilitation Projects
Sacramento, Calif. – January 11, 2016 – a leading provider of smart water leak detection 
technologies and cloud computing applications, announced that its patented technology has been prominently featured in a new edition of the industry’s leading wastewater collection manual – OPERATION AND MAINTENANCE OF WASTEWATER COLLECTION SYSTEMS, VOLUME 1, SEVENTH EDITION.
First published in 1976 with nearly 90,000 copies in print, the OPERATION AND MAINTENANCE OF WASTEWATER COLLECTION SYSTEMS manual is used by operators, managers, and consulting engineers, worldwide.
The Seventh Edition was published in December 2015, while the Sixth Edition was published in 2003.
“Our manual was originally designed to allow for self-paced instruction where operators worked at their own speed,” said Ken Kerri, Ph.D., P.E., former Director of the Office of Water Programs, California State University, Sacramento (1965-1997) and Chief Project Consultant until his passing in 2014.
“Once operators started using the manual for home study, we realized that it could serve as a textbook in the classroom,” said Dr. Kerri, who co-authored the section on Electro Scanning Inspection.
Today, the Office of Water Programs is a nonprofit organization operated by University Enterprises, Inc., California State University, providing distance learning programs for the operation and maintenance of drinking water and wastewater facilities.
“We are delighted to see our technology become an integral part of Chapter 4: Inspecting and Testing Collection Systems,” states Chuck Hansen, Chairman, Electro Scan.
Electro Scan’s technology is not only explained in Section 4.4 of the Seventh Edition, but also depicted in numerous illustrations, statistical analyses, and practical applications, in accordance with ASTM F2550-13.
In numerous instances, Electro Scan’s low voltage technology is able to identify and quantify leakage amounts in gallons per minute (GPM), often where defects are not identified by certified closed-circuit television (CCTV) operators or by using other inspection techniques.
Electro Scanning Inspection also provides wet-weather condition assessment information, not available using CCTV inspection, and can be performed year around to help locate sources of sanitary sewer overflows (SSOs) and find defects in newly repaired or relined pipes.
Important updates contained in the Seventh Edition suggest altering the acceptance criteria for rehabilitated pipes using Electro Scanning Inspection to assess the effectiveness of cured-in-place pipe (CIPP), service re-connections, and point repairs, explaining the importance of quantifying pre- and post-rehabilitation inspection results.
Given Electro Scan’s ability to automatically find sources of leaks that are frequently missed by CCTV inspection, the manual suggests using Electro Scanning Inspection first to objectively locate and quantify pipe defects, then using CCTV inspection to document the most severe defects.
In addition to Electro Scanning Inspection (Section 4.4), Chapter 4: Inspecting and Testing Collection Systems also includes an updated section on CCTV Inspection (Section 4.3), Smoke Testing (Section 4.5), and Dye Testing (Section 4.6).
Continues Hansen, former Founder and CEO of Hansen Information Technologies, “It was an honor to contribute to Electro Scanning Inspection at the invitation of Dr. Kerri and share this game-changing technology with operators, managers, consulting engineers, and students.”
