Sanitary sewer overflows (SSOs) are most often caused by the long-term buildup of roots, fats, oils or grease within a pipe. An acoustic inspection is a cost-effective way to detect blockages before an overflow or maintenance issue occurs. A transmitter is installed in a manhole that transmits a series of tones through the air gap within the pipe. A receiver is installed in an adjacent manhole and it listens for degradation in tones compared to a clean pipe. The data are analyzed in less than three minutes and rate the severity of the blockage on a scale from 0 to 10.
The RehabZone would not be possible without the generous contributions of industry leaders, companies and organizations that share UIC’s vision to set standards for the assessment, maintenance and rehabilitation of underground infrastructure and to assure the continued acceptance and growth of trenchless technologies.
