Aging of Pipe Infrastructure
Average age of water pipes has increased to 45 years in 2020 from 25 years
in 1970 (1)
2.2 million miles of underground pipes for drinking water with 240,000
water main breaks per year (2,3)
Up to 30% of treated water is lost or unaccounted for in the water system (5)
Growing number of states requiring water loss audits (6)

Water Main Break Rates Increasing
(4)
According to a study by Steven Folkman at Utah State University
that surveyed nearly 200,000 miles of water pipelines in more
than 300 municipalities in the U.S. and Canada, serving more
than 14% of the two countries' total population:
-
Between 2012 and 2018, overall water main break rates increased
by 27%, to 14 from 11 breaks/100 miles/year
More concerning is that breakage rates of cast iron and asbestos
cement pipe which make up 41% of the installed water mains in
the U.S. and Canada - have increased by more than 40% over those
six years
82% of cast iron pipes are more than 50 years old and experiencing
a 46% increase in break rates
Smaller utilities have two times more main breaks than large utilities
Nationwide, one mile of installed water main serves 308 people
The average age of failing water mains is approximately 50 years
Over 16% of North America's underground water infrastructure is
past its design service life
