Mapping and Analysis of Water Main Breaks

 

The Village of Tinley Park has detailed records on water main breaks.  To see spatially where these breaks are happening provides an addition tool when examining where breaks are most frequent and can assist in the planning of future budgets on capital improvement projects.  Tinley Park’s public works department recently asked the GIS Consortium to create a map displaying where every single water main break has occurred within the village.  The GIS department was able to find historical water main break data from as early as 1981.  Plotting the break data from 1981-2013 provides a unique outlook on the state of the water system and will shed light on areas that need to be looked into for future replacement.

Identifying areas with a high number of breaks is just one step in analyzing the water system.  The village can dig deeper and evaluate types of material that are most common for breaks, what role if any does water main depth play, or even the average age of the water mains that are breaking.  With GIS, the Village of Tinley Park has the resources available to track and analyze these questions.
