Utilizing the warm well water for a geothermal greenhouse heating system is highly economically feasible. This is based on using the 88/sup 0/F water from Anderson Well No. 1 to heat greenhouses totaling approximately 10.6 acres. The additional investment of $640,000 above the cost for a conventional electric boiler system shows a rate of return of 48.3% on a 20 year life cycle analysis. The simple payback is 3 years. The 88/sup 0/F well water is not warm enough for prawn (Macrobrachium rosenbergii) aquaculture, since water flow requirements are excessive to maintain the desired 80/sup 0/F pond temperature. However, the water is warm enough to maintain a 60/sup 0/F pond temperature for trout farming. Trout farming using the 88/sup 0/F well water directly is probably not economically feasible due to high electrical pumping cost (34,626 per year) for the seven 1/2 acre ponds that could be heated. Trout farming using the 75/sup 0/F effluent water from the 10.6 acre greenhouse to heat four 1/2 acre ponds may be economically feasible since the water booster pumping cost is low $1189 per year.
