As a supplement to this inventor's prior U.S. Pat. No. 5,727,621, this invention provides, in the combination with that patent, the additional concept of a terminal receiver means. It provides appropriate cleansing and testing features for the water which has served its geothermal purpose. The thermally-used geoexchange water is routed back to the primary water line at an inlet thereinto which is close to the primary water line's outlet from which that water had been drawn, providing a great savings of a lengthy "return" line, entered upstream of the distant primary water-treatment means as contemplated in that prior patent as being the presumably necessary way of certainty of elimination of any contamination entered to water by the geothermal usage. |
