COST-EFFECTIVE GIS SOLUTION FOR BURIED INFRASTRUCTURE MEETS REGULATORY REQUIREMENTS FOR ALLEN COUNTY SANITARY ENGINEER

The Allen County Sanitary Engineering Department was required to develop an Inflow/Infiltration (I/I) identification and reduction program in an effort to prevent Sanitary Sewer Overflows (SSO). Management of the data and coordination of the inspections was crucial for this project to be a success. With no existing digital information, the County decided to take a two front approach: 1) develop a Geographic Information System (GIS) of their sewer network and 2) perform a detailed condition assessment. The GIS would become the means by which the condition assessment process and its resulting data would be organized. Once completed the County would be armed with the information needed to efficiently and effectively correct their SSO problems. This paper reviews the process that Allen County and its consultants went through to achieve their goals.
