Pressure Pipeline Condition Assessment

Download a recording of our informational webinar on pressure pipeline condition assessment, with a focus on knowing which technologies to use. Insight is vital to cost-effective management of pipeline infrastructure as competing challenges – aging systems, rising costs, environmental well-being and service expectations – are fueling a need to do more with less. Learn about: • Optimizing projects by understanding what you have • The advantages and disadvantages of available technologies • Best practices for rehabilitation and replacement The webinar is led by Bryon Livingston, P.E., a senior project engineer at Black & Veatch. Bryon has more than 28 years of experience assessing water and wastewater pipelines, pipeline design, and the construction and operation of water supply, treatment and distribution facilities. His well-rounded perspective is based on his municipal experience, including serving at the director and senior project management levels for cities in Oklahoma and Kansas. The slide presentation of the 16 Dec. 2015 webinar is available here: https://pages.bv.com/Pressure-Pipeline-Condition-Assessment.html Stay informed with Black & Veatch.

THE CONDITION OF CONDITION ASSESSMENTACCORDING TO THE EPA 16 Dec. 2015 44 Black & Veatch • Condition assessment is either not used or not used routinely by a most utilities • Utilities often have little data in system besides the type of pipe, type of service and installation date • If inspections have been conducted usually only have qualitative (Good/Poor) information – not useful • Utilities are leery of new inspection techniques and need to be educated on how to use effectively • Repair or replacement typically only occurs after major failure event and associated negative attention

BEST PRACTICES 16 Dec. 2015 45 Black & Veatch • Empowers Utility to act as Steward of Community Water Infrastructure • Encourages Proactive Investment • Facilitates Continuous Improvement • Requires Prioritization of Pipes in the System and Condition • Significant Emphasis on Collecting the Quantity and Quality of Data Collected Needed to Determine Status of Pipeline R3 = Replace RIGHT pipe, RIGHT time, RIGHT material
