Sanitary Sewer Systems

system-evaluations2Stiffler McGraw has extensive experience in Inflow/Infiltration (I/I) studies for sanitary sewer systems. Our firm owns internal televising equipment, smoke testing equipment and flow meters. We use this equipment to thoroughly evaluate your sanitary sewer system to isolate areas where attention is needed. An I/I study is a structured approach to identify and quantify extraneous flow sources entering the system. The elimination of these flows can significantly reduce costs at your treatment facility because groundwater and storm water do not pass through the treatment process.

In addition to this, it is common for our technicians to perform an inventory of all manholes in the system to record their condition and location. If requested, the manholes can be located using GPS equipment to assist in future location or to be entered into an asset management program. Our firm has completed numerous sanitary sewer system I/I studies in rural and urban settings in commercial, residential and industrial districts throughout Pennsylvania.
