Title
P-CAT Watermain Scanning - ITB #26-050
History
The Utility Division has been researching ways to determine the condition of larger watermains without excavating or disrupting service to residents for the purpose of replacing or rehabbing the larger mains, as it is very expensive due to their size.
Pipeline Condition Assessment Technology (P-CAT) is a non-invasive, non-destructive technology for performing pipe assessment. It can determine remaining wall thickness over long sections of pipeline, as well as detecting and locating defects such as air pockets, internal blockages, unknown connections, and pipe material changes.
P-CAT works by analyzing the partial reflection of a small, controlled transient signal that is injected into the pipeline using a fire hydrant. The signal is monitored and recorded by sensors that are temporarily installed on existing pipe fittings. The transient wave experiences partial reflection when it encounters any change in pipeline structure. The data is analyzed by a computer program, which sends out a location on the pipe where it picked up any defects.
This technology saves costs by locating defects within the pipeline and limiting repairs and replacements to only the sections in need of attention. To date, P-CAT is the most comprehensive and advanced solution for long distance pipelines.
The Utility Division will utilize P-CAT to scan all the Village’s watermains that are sixteen (16) inches and larger in diameter. By scanning all the larger mains, the Utility Division can start prioritizing which mains should be repaired or replaced before those mains start breaking with regularity.
