Abstract The overall objective of this EPA funded study was to demonstrate innovative a sewer line assessment technology that is designed for rapid deployment using portable equipment. This study focused on demonstration of a technology that is suitable for smaller diameter pipes (less than 12 inch diameter). The recently developed and commercially available acoustic based sewer pipe assessment technology demonstrated during this study was the Sewer Line - Rapid Assessment Tool (SL RAT(TM)) manufactured by Info Sense, Inc. (Info Sense) of North Carolina. This technology can provide a rapid assessment of the need for pipe cleaning. Acoustic technologies require a minimal amount of equipment when compared to traditional closed circuit television (CCTV) inspection systems. This acoustic based technology has the potential to provide information in a matter of minutes to assist an operator in determining whether a sewer pipe might be partially or fully blocked and require cleaning or renewal. The speed of the assessment, using minimal equipment, has the potential to result in significant cost savings compared to traditional methods, such as CCTV inspection. It is generally known that smaller diameter pipes (i.e., less than or equal to 12 inch diameter) contribute to over 90 percent of the sewer main backups reported in a typical city (Sprague, J., 2007). This study hence focused on the demonstration of an acoustic technology that is suited for smaller diameter pipes. This collaborative field demonstration of the SL RAT was led by EPA's National Risk Management Research Laboratory (NRMRL) in Cincinnati, Ohio. EPA worked with the Metropolitan Sewer District of Greater Cincinnati (MSDGC) as a collaborative research partner to identify study locations, provide access to the study area sewer lines and to perform the related field work. Specifically, the data and information obtained from the following technologies were used in this demonstration project: SL RAT; Pan Tilt Zooming pole mounted camera (aka 'camera on a stick') manufactured by Envirosight Quickview; and HD digital scanning CCTV or the PANORAMO 3D Optical Pipeline Scanner manufactured by Rapid View IBAK.
