GIS Supports Relief Sewer Identification


Being able to get access to useful information at a moment’s notice
is something of a common trend these days. The only problem that really
arises is when the information you are searching for is not yet
created. As technology advances, so do the amount of portals that are
created to store mass amounts of information. One type of portal that
has been around for a long time is a Geographical Information System
(GIS). This type of information portal does not only store tabular data
but it also represents this tabular data in a spatial environment so
that correlation​s can be made between the different types of data on the

The City of Park Ridge, IL has been using a GIS for many years now
but they always seem to find new information that is worth adding to the
system in order to answer everyday questions or conduct detailed
analysis. One of the newer additions of data to the GIS is the
collection of relief sewer locations. This data is important to the
Engineering Department in order to understand where these relief sewers
are located in relation to other sewer lines as well as how they are
helping the overall flow of storm water in a certain area. Older
methods would have usually required the City Engineering Department to
dig up and review old as-builts and document where these lines are
located. Now the information is stored in the GIS and is as easy as
looking at a map for their review and analysis. A once labor intensive
process has now been made more efficient with the help of GIS.
