Description:
The Office of Research and Development’s National Risk Management Research Laboratory has published this report in support of the Aging Water Infrastructure (AWI) Research Program, which directly supports the Office of Water’s Sustainable Water Infrastructure Initiative. Scientific and engineering research is being conducted to evaluate and improve promising innovative technologies that can reduce costs and improve the effectiveness of operation, maintenance, rehabilitation, and replacement of aging and failing drinking water distribution and wastewater conveyance systems. Failing wastewater collection systems can pose a significant threat to public health and the environment. Systems with inadequate hydraulic capacity and/or blockages may lead to sanitary sewer overflows and may cause flooding damage to private property or release untreated sewage to receiving waters. This publication summarizes the current state of condition assessment technologies, which provide the critical information needed to assess the physical condition and functionality of a wastewater collection system and estimate remaining service life and asset value. This document also addresses the dynamics of wastewater collection system failure by discussing mechanisms of pipe failure, the various types of pipe defects, and the relationship between the condition of a pipe and its performance. Inspection technologies and their use in condition assessment for wastewater collection systems are also presented, and each technology is briefly described, and commercially available and emerging technologies are discussed.
