  Condition Assessment of Wastewater Collection Systems - State of Technology Review Report (EPA/600/R-09/049) May 2009

Report Cover: Condition Assessment of Wastewater Collection Systems - State of Technology Review Report
The objectives of Task Order 59 are to comprehensively review condition assessment technologies and to investigate condition assessment approaches for wastewater collection systems. Specific project objectives include:

  • Identify and characterize the state of condition assessment technology for wastewater collection systems.
  • Research and evaluate performance and cost of innovative and advanced infrastructure monitoring technologies including wireless and remote sensing approaches developed in other industries and their applicability to wastewater collection sewers.
  • Identify and evaluate innovative closed-circuit television (CCTV) technologies currently used by more advanced wastewater utilities for transfer to utilities at large.
  • Prepare protocols, metrics, and site selection criteria for field demonstration of selected innovative condition assessment technologies and decision-support systems.

This White Paper is one of the first work products created under Task Order 59 and was used as a basis for discussions at the project’s Technology Forum in September 2008. The White Paper summarizes the current state of condition assessment technologies, reviews mechanisms of pipe failure, discusses emerging and innovative technologies for sewer inspection, and presents a summary of the Technology Forum. It incorporates feedback received at the Technology Forum.
