Description:
The average rate of water and wastewater system rehabilitation is not adequate to keep pace with increasing needs, quality demands, and continually deteriorating systems. Rehabilitation technologies in use today are generally effective, but there is still considerable room for improvement in existing technologies and/or development of new technologies. Such improvements offer opportunities to make investments in rehabilitation more effective and extend the ability of utilities to fix larger portions of their systems with current funding levels. As part of the U.S. Environmental Protection Agency (EPA) Aging Water Infrastructure Research Program, several areas of research are being pursued, including the need from a rational and common design approach for system rehabilitation, quality assurance and quality control (QA/QC) procedures and acceptance testing during installation of rehabilitation systems, decision support for choice of rehabilitation versus replacement and selection of rehabilitation systems, and special applications of rehabilitation under challenging conditions. Presented in this paper are the results of the state-of-technology review for rehabilitation of gravity sewer systems, sewer force mains, and water mains to assess data gaps and future research needs. Findings from a review of QA/QC practices for rehabilitation projects will be presented. Plans for a cured-in-place pipe (CIPP) retrospective evaluation and innovative rehabilitation technology demonstration field program will also be discussed.
