Publisher's Synopsis
The failures from gradually deteriorating joints are observed as leaks or pipe breaks at or near the joint and may result in water quality deterioration. However, while these failures are not often catastrophic, they frequently remain undetected or are not acted upon. If the condition of a joint can be assessed prior to the onset of visible deterioration, it may be possible to undertake planned remedial action to prevent further degradation and expense.
- Determine the types of joints that are most common and their major potential modes of failure
- Perform a utility survey to determine methods currently being used for joint location, condition assessment, and repair
- Undertake a literature and manufacturer search of current and emerging technologies used for location, condition assessment, repair, and rehabilitation of pipe joints
- Investigate and report on the performance of selected technologies
- Perform utility sponsored field testing of selected techniques under a variety of realistic site conditions
- Develop decision support tools and methodologies based upon the technical attributes of the particular systems
