Utility prioritizes pipe replacement projects and reduces planning time by 75% using advanced risk analytics

The City of Raleigh Public Utilities Department (Raleigh Water) maintains the water and wastewater infrastructure for 600,000 customers in Raleigh, North Carolina, and six surrounding communities. Raleigh’s drinking water distribution system originally dates to 1887 with the construction of the City’s first water treatment plant. The utility has documented several cast iron pipes installed as part of the original system throughout the heart of downtown Raleigh.

In 2019, Raleigh Water partnered with Xylem’s team of industry and technical experts to conduct a probability of failure analysis of the utility’s entire network using Xylem Asset Performance Optimization services. Xylem combined historical pipeline break data with other infrastructure data from Raleigh Water’s Esri ArcGIS enterprise system to identify the top 1% of at-risk pipeline segments based on their probability of failure.
