Solutions for Managing Prestressed Concrete Cyclinder Pipe (PCCP)

Large diameter prestressed concrete cylinder pipelines (PCCP) are a significant investment for many water and wastewater agencies. Assessing and monitoring the condition of these pipes is becoming an increasingly important and challenging task. Pure has a comprehensive suite of services to better understand the condition of and manage PCCP mains.

Some water utilities have limited access to the buried pipe. Other agencies have little redundancy built into the system, requiring owners to conserve water as much as possible and keep pipelines in service. Corrosion-induced failure in the wire wrapping of PCCP can result in ruptures with consequent interruption in service, potential flood damage and public safety concerns.

	Electromagnetic Inspection Electromagnetic inspection technology accurately establishes the baseline condition of prestressed concrete cylinder pipes (PCCP) by detecting and quantifying the number of breaks in prestressing wire that reinforces concrete pipes.
	Leak & Gas Pocket Detection Pure’s leak detection systems are non-destructive, in-line, condition assessment tools that can detect leaks and gas pockets in live pipelines. These systems are used primarily on larger diameter water and wastewater transmission mains of all materials as well as oil & gas pipelines.
	Structural Monitoring Providing real-time critical data of a prestressed pipeline allows the asset owner to effectively moniture changes in structural integrity and address necessary improvements.
	Structural Analysis Software that incorporates structural and environmental information along with all evaluation data to provide a dynamic near-real time condition assessment of each pipe that is used to predict the remaining useful life of the pipe.
	Pressure Transient Monitoring Engineers and utility operators are increasingly concerned that transient and surge pressures are adversely affecting the condition of their pipelines. The TP-1 system can accurately record and plot detailed pressure information that can be used to improve current pipeline operation practices.
	Visual Inspections and Soundings Visual Inspections and Soundings have successfully been used to quickly identify pipes in the state of incipient failure. Issues other than wire breaks can also be identified through visual inspections, such as unusual cracking and poorly detailed or damaged joints.

Pure Technologies operates under a policy of open sharing with our technologies’ capabilities and limitations. We regularly author technical papers on the topic of assessing, monitoring and managing PCCP mains to ensure our clients have the latest knowledge of how to manage PCCP mains.
