A geothermal energy installation and system (10), in which the field of potable water (12) is utilized by a secondary conduit system (32) to route potable water (12) from an inlet (18) in the user's line (16) coming from the potable water field (12) but upstream of the user's meter (24), through the heat exchanger equipment (30) of a user, and back to the field (12) at a point upstream of the final treatment processing stage of the field. Thus, the thermal energy of the water of the field (12) is utilized without adding the cost of the volume of potable water used (27) by the user, and is re-processed if somehow contaminated in the secondary conduit systems (32); and although the secondary conduit system (32) delivers water back to the field (14) at a changed temperature, depending upon the heat exchanger (30) effect, the relatively large volume of water of the potable water field (12) assures that the returned water does not even substantially alter the temperature of the potable water field (12).
