Normalized water main breaks


With the winter coming to a close shortly, the excessive season of
main breaks is almost over. Water main breaks take away from resources
and time that could be put into improvement projects. The easiest way to
calculate the number of main breaks on a village street or water main
line is to simply count each break and add it up; however, this data
collection method only will give you the number of main breaks, it
doesn’t account for the significance of those breaks to the integrity of
the line as a whole.

This new method used in the analysis uses Geographic Information
Systems to normalize the number of water main breaks on each segment by
taking the number of breaks on a line and comparing that with how short
that line is. As you can see in the map, the higher number of main
breaks on a segment has a darker shade of blue. If two different water
main lines have the same number of breaks in a given year, the water
main line that is shorter will have a higher normalization of breaks.
Based on this information, the shorter water mains are prone to higher
normalization scores. Finding the water mains that have multiple breaks
over short distances, will help Public Works and Engineering identify
the water mains that need improvement the most. This analysis will save
funds, by highlighting to Public Works the main problem areas of the
Village’s Water Main Network.
