Well with our location this ruddycrazy idea might work, we get indirect mains which comes from the property across the road and the head is around 300ft, just off gravity pressure the hose can spray water over the house. Now I have a 150 ft 3" uncased hole not far from the house so by running the water thru a closed dual pipe in that hole then into a homemade 24 volt swamp cooler should provide plenty of nice cold water. The best part it will only run when the swamp cooler float goes down far enough to want more water. With my new toy turning up in the next couple of weeks (a MF50B backhoe) digging the trench's will be fun while holding a coldie in one hand....
