Development of a Framework and Business Processes for GLWA’s Linear System Integrity Program

The Great Lakes Water Authority (GLWA) has implemented a Linear System Integrity Program (LSIP) to manage the risk of their extensive water linear piping network. Understanding the condition of their pipe assets is critical to GLWA’s objective of minimizing service failures and improving the overall resiliency of their transmission system. Through the LSIP, GLWA is using pipe condition assessment to drive targeted improvements to its transmission main system. In order to successfully accomplish their objective, GLWA has developed an extensive framework, which serves as the core to the implementation of the program. The framework allows GLWA to maintain consistency, inform, and engage stakeholders as needed, and allows for clear, repeatable processes. In addition to the framework, GLWA has developed business processes for determination of the most applicable pipe assessment method and renewal techniques.
