Virginia City Selected for Sewer Inspection Pilot Program
Electro Scan Inc. has selected the City of Galax, Virginia for a complimentary pilot to find and measure sources of infiltration in their sanitary sewer system.
The City of Galax was selected because of their unique project attributes, pipe locations and criticality, and financial need. The 2-day project is expected to start in the fall of 2017, and will include the assessment of 5,000 linear feet of vitrified clay pipe and polyvinyl chloride pipe. A full report will be provided to the city, quantifying potential infiltration in gallons per minute to help them prioritize pipes for rehabilitation.
From 2003 to 2013, the City of Galax was under a Consent Decree from the United States Environmental Protection Agency and the Virginia Department of Environmental Quality where they were required to develop a Capacity, Management, Operation, and Maintenance (CMOM) Program.
“Initial CMOM inspection projects were able to identify and eliminate the larger, more obvious infiltration issues, but locating additional infiltration problem areas has since become very difficult,” Edwin Ward, P.E., City Engineer, City of Galax, said. “We are happy to have been selected for the Electro Scan Pilot because of the technology’s ability to find and measure potential sources of infiltration, even if there is not an active leak in that moment.”
Electro Scan Inspection uses patented technology to measure the variation of electrical current that flows through cracks, bad joints, defective service connections, and other defects in non-conductive pipe materials. Using its Critical Sewers® cloud application, defects are automatically located and measured in GPM, with unambiguous reports available in minutes from any device with an internet connection.
“CCTV operators are rarely successful when they are forced to wait for a wet weather event to put a camera in a pipe to visually look for infiltration in an overwhelmed collection system,” said Chuck Hansen, Chairman, Electro Scan Inc. “Electro Scan creates a wet-weather event from within the pipe to predict infiltration before it happens, and before a disastrous SSO occurs.”
