Predictive Modeling Reduces
Pipe-Failure Risk, Impact
for Raleigh Water
Global water technology company, Xylem,
helped the city of Raleigh Public Utilities
Department (Raleigh Water) get a clearer picture
of its 2,340 miles of pipes, some of which are
more than 100 years old.
Xylem Asset Performance Optimization
analyzed the utility's entire network, combining
historical pipeline break data with information
from Raleigh Water using Esri ArcGIS Enterprise
software. The resulting assessment identified the
top 1% percent of at-risk pipeline segments, based
on their probability of failure.
With this highly accurate, predictive, and targeted
view of potential trouble spots throughout the city, the utility was better able to decide which ones to prioritize. In addition, the data-driven risk model supports a
city-wide initiative to increase racial equity by eliminating bias from selection of infrastructure projects.
The process also increased efficiency, taking 45 percent less planning time than in the past, while avoiding unnecessary digs, reducing capital costs and water loss
from pipe failures, decreasing response time and lessening other impacts on the community.
To date, Raleigh Water has planned six projects using the results of Xylem's analyses.
" Based on what we've seen with Xylem's predictive modeling services, we are confident that replacing these mains is the best bang for the buck, " said Adam
Haggerty, asset manager for Raleigh Water. " This is a game changer for us, and it is something we will be able to use for a wide variety of applications. " .
Xylem is a Rye Brook, N.Y., global company committed to solving critical water and infrastructure challenges with innovation. Its solutions are creating a more
sustainable world by enabling customers to optimize water and resource management and helping communities in more than 150 countries become water secure *.
