Join ICG while they present a targeted approach to inspecting different types of water pipelines common in the industry. Many times, pipe condition data is limited, so decisions on where to directly assess pipelines are made based on leak history or Operator knowledge alone. There is, however, a more targeted approach that utilizes a variety of indirect inspection technologies, both above ground and internal, that when collected and analyzed together, can paint a more accurate picture of a pipeline's overall integrity.

Once this data is compiled, excavation locations can be selected in order to expose the most degraded anomalies along portions of pipe. This approach will save Operators more money in the long run by extending the life of the asset and minimizing resource allocation.

As these survey methods are implemented across an entire system, the data can then be used to create a Relative Risk Model. The Risk approach has been developed and refined in other pipeline industries and can be modified to fit the water industry's specific operating conditions and needs. Operators can utilize Risk Models to allocate resources over an extended period of time with the goals being to minimize Risk and prolong asset life.
