The Value Proposition for Likelihood‐of‐Failure Modeling
Water infrastructure needs continuous renewal or replacement, and in North America, a recent study showed that water main break rates have been increasing (Folkman 2018). Because they need to make informed decisions regarding pipe replacement, water utilities can struggle with balancing system needs with customer rates and fees. It makes sense to allocate funding to pipes that are more likely to fail, thereby improving capital efficiency while maintaining or increasing customer service.
Validation of water main failure predictions: A 2‐year case study
1 INTRODUCTION The water infrastructure in North America is deteriorating. Recent studies show that water main break rates have increased by 27% during 2012–2018 (Folkman, 2018). Among the pipe materials used in the distribution system, the main break rate of cast iron pipes increased by greater than 40% (Folkman, 2018). With the accelerated pipe failures, more funding is needed for pipe replacement.
