GIS Keeps Water and Revenue Flowing

Aging infrastructure affects not only water delivery, but the revenue stream in municipalities. When water mains leak or break, the Village of Tinley Park, IL responds quickly to assess the damage and fix the problem.

Over time, sections of the water main leak or break repeatedly, prompting replacement. To be more proactive in determining which pipes to replace, the village’s Public Works department turned to Geographic Information Systems (GIS) staff to analyze incidents over location and time and determine which sections are high priority.

The analysis compared the age, location, and number of incidents on each pipe section throughout the village. By comparing the density of leaks and breaks within a 33-year period and a more recent 10-year period, those sections with the most incidents were identified and highlighted in maps.

Using these maps, Public Works easily prioritized which ones to replace in the upcoming year. The GIS analysis also gave staff insight into areas of town where leaks and breaks would likely occur in the future.
