No More Failures: Charlotte Water Strengthens Its Commitment to a Comprehensive Management Strategy Targeting Large Diameter PCCPs
Publication: Pipelines 2023
ABSTRACT
Charlotte Water is the largest public water and wastewater utility in the Carolinas and greater Mecklenburg County, including the towns of Matthews, Mint Hill, Pineville, Huntersville, Davidson, and Cornelius. Their vast system includes many large diameter arteries that collect and deliver its water supply. For years they have taken a proactive approach in understanding and managing the condition of their pipeline infrastructure. Population and service demand growth over the last decade has moved Charlotte Water to lean in and use its existing resilience to stay ahead of unexpected large diameter concrete pipeline failures. Charlotte Water has faced the challenge of measuring and calculating risk within its aging, irreplaceable, concrete pipelines, and is now able to prioritize incremental inspection and repair, and earmarks capital funds appropriately in future years. Beginning with two of their most critical pipelines, the utility now understands how to manage these large diameter concrete pipelines within a full asset management cycle that has been established around a comprehensive, tailored, pipeline management strategy.
