Water supply systems: Getting younger but still fourth oldest

Average age of water supply systems was reduced from 21.8 in 1994 to a low of 14.8 years in 2007, in the wake of strong investment over the years. As a percentage of estimated useful life, the provincial rate has historically been substantially higher than the national average until recent years.

In 2007, the provincial ratio was 40%, equal to the Canadian average. Water supply systems accounted for 4% of Prince Edward Island infrastructure, the smallest proportion among provinces.
