SEWER RENEWAL - A STRATEGIC PLAN AS PART OF EPA's CMOM PROGRAM

摘要

This paper demonstrates the development of a comprehensive sewer renewal and I/I reduction program - a "Total System" approach. Accurate flow monitoring and interpretation, and the lessons learned from halting groundwater migration around renewed sections of sewer are shown to be essential for success. EPA's initiative to improve the Capacity, Management, Operation, and Maintenance (CMOM) of public sewer systems will provide additional impetus to conduct sewer renewal and a need to document the effectiveness of this work. Tools for estimating program costs based on compiled case histories (including detailed information from Nashville), will be presented. Finally, a "fast track" sewer renewal strategy derived from successful I/I reduction work will be described. This paper is the first of three papers presented as a seminar entitled "Putting the Pieces Together", intended to address various elements needed for developing a successful, overall municipal sewer renewal and overflow elimination strategy. The companion papers are Sewer Lateral Renewal Crucial to "Total System" Success, and Flow Knowledge - A Tool to Target Sewer Renewal or Upgrades. Some material has been repeated in all three presentations so that each paper will represent a complete report.
