Geographic information systems (GIS) have been around for
decades, but only in the past 10 years or so has technology
been developed that makes GIS useful to the mainstream
needs of water utilities and public works departments. This
article provides examples of how utilities in Canada, the United
States, and Australia are using GIS to manage and maintain their
water distribution networks and provides information about how
GIS can be used to analyze the data collected during a water
main corrosion study.
The authors use the results of a geographic analysis of the data
collected during a study of Toronto, Ontario's cast-iron water mains to
begin to quantify their risk for deterioration. The study results also
provide new information regarding the relationship between soil
properties and the external corrosion of cast-iron water mains. Includes 8 references, table, figures.
