EPA Report on SewerBatt – Part 2

EPA Report on SewerBatt – Part 2

13-Feb-2015 The United States Environmental Protection Agency (EPA) has published a report Demonstration of Innovative Sewer System Inspection Technology SewerBatt™

The overall objective of the EPA-funded study was to demonstrate innovative sewer line assessment technology that is designed for rapid deployment using portable equipment. The study focused on demonstration of a technology that is suitable for smaller diameter pipes (less than 300mm diameter).

Acoustic energy naturally follows a pipe’s curvature. Obstructions within the pipe will cause a portion of the acoustic energy to be reflected and absorbed. In addition, unless the obstruction is significantly dense, a portion of the acoustic energy also passes through. These inherent physical properties of acoustics within pipes provide the mechanisms for evaluating a pipe’s condition. Based on these mechanisms, acoustic inspection technology such as SewerBatt ™ is capable of quickly evaluating the presence of blockages, features, and defects in the interior of sewer pipes and provide informed decisions relating to the need for cleaning or further inspection using other available technologies.

The emergence of acoustic sewer inspection technologies such as SewerBatt™ as rapid deployment, low-cost, reliable, pre-cleaning assessment tools is focusing growing attention on the potential for more cost-effective sewer cleaning programs. Through the ease of deployment, reduction of cost, increases in reliability of these inspection approaches, combined with the potential for reducing the “cleaning of clean pipes,” significant cost savings are attainable. As utilities apply these new inspection technologies, they can move towards implementing sewer cleaning programs that consist of planned directed and quick response cleaning. Also, these cost savings can be realised while improving collection system performance and achieving the protection of public health and water quality.
