Water supply systems in Saskatchewan have generally benefited from sustained investments since 1982, when the average age was 21.6 years. In addition, the rate of investments in these assets accelerated after 2000, following the national average rate of 5.1% per year.
As a result, the average age of water supply systems in Saskatchewan reached an historic low of 15.1 years in 2007. Water supply systems were the second most important public infrastructure in the province in 2007, accounting for 13% of the total stock.
As a percentage of estimated useful life, Saskatchewan has historically been above the national average, but the gap has narrowed substantially by 2007. The rate was 41% for the province compared to 40% nationally.
