IMPUTED WELL & IMPUTED SEPTIC TANK DISCLAIMER No database currently exists for the location of private wells or septic tanks. The point locations shown on this map were determined using various assumptions and existing GRU customer data as follows: The location points were deduced from GRU accounts that had electric service but not water and/or wastewater. These points were given a cursory screening for obvious errors, but have not been field verified or screened further. There are undoubtedly many false positives included in the data, as well as many omissions. The points were then overlaid with our existing utility network to determine if they could be served by an adjacent main, or conversely, if they would require a main extension. They were then segregated by this criteria. Note that elevation was not taken into account in determining potential serveability.
