The tank is usually constructed out of concrete, so we first use a probe and/or a metal detector. If finding the tank is difficult by these methods, an electronic locator can be used at an extra charge. This electronic locator is able to locate the general area of the tank (as long as there is not a blockage from the house plumbing to the tank) if the tank may be close to or under a deck, patio, pool patio, room addition, or if the tank is constructed of plastic. The homeowner may also contact the county to obtain records on the system, which usually includes a layout, although not all layouts are accurate.
