Abstract
 Using a GIS to Predict Sanitary Sewer Overflows Track: Water, Wastewater, and Stormwater Author(s): Joseph Molis Sanitary Sewer Overflows occur throughout the country, cause severe environmental and economic damages, and can expose the public to a variety of pathogens. GIS analysis can provide a quick and inexpensive means of evaluating an area for determining the likelihood of a Sanitary Sewer Overflow occurring. Currently, efforts to predict and eliminate Sanitary Sewer Overflows have relied on the use of hydraulic modeling and extensive collection system inventories and inspections. This methodology is often expensive and can take many years to complete. Based on historical information about the causes of Sanitary Sewer Overflows and their distribution, it is possible to identify areas at greater risk of their occurrence and direct study efforts to those regions. This paper will present an approach to using a GIS to analyze general spatial characteristics of a Texas municipality's wastewater collection system and compare the results to known historic occurrences of Sanitary Sewer Overflows.
