About P-Wave®

P-Wave® is a proven proprietary electromagnetic inspection technology for evaluating the current condition of pre-stressed concrete cylinder pipelines (PCCP).

Owners of water and wastewater pipelines can use P-Wave® to identify distressed pipe sections within their infrastructure. This allows them to target their maintenance, repair and replacement programs to where they are needed most. Once a pipe is dewatered, P-Wave® equipment can be deployed to locate and quantify existing wire breaks along individual pipe sections.

How it works

P-Wave® generates an electromagnetic field inside a PCCP and measures the changes within this field caused by broken wires. By providing information on the number of broken wires in each pipe, P-Wave® enables the most effective remediation strategy to be put into action.

P-Wave® is often used as a first step in a long-term management program for prestressed pipelines.  Once the survey is completed and the current condition of the pipeline is determined, a long-term acoustic monitoring program can be instituted, in conjunction with a GIS-based structural risk management program, to ensure the long-term integrity of the asset.
