This paper will present applications of a global positioning system (GPS) in wastewater management. The new line of GPS receivers brings technology to wastewater system operators and managers who can populate maps with precise location of features such as manhole covers, catch basins, and overflow points. GPS technology can also be used to verify the locations of wastewater system point features such as valves, pumps, flowmeters, and rain gauges. The paper will also show how GIS software can be customized using scripts to integrate GPS data with a wastewater system GIS database.
