Under a gravel border around the house, a concrete gutter channels the water into a 25,000-gallon cistern for irrigation. In hot weather, a terrace directly above the cistern is a little cooler than the surrounding area.
Wastewater from showers, sinks and toilets goes into purifying tanks underground ? one tank for water from showers and bathroom sinks, which is so-called "gray water," and one tank for "black water" from the kitchen sink and toilets. The purified water is funneled to the cistern with the rainwater. It is used to irrigate flower gardens, newly planted trees and a larger flower and herb garden behind the two-bedroom guesthouse. Water for the house comes from a well.
The Bushes installed a geothermal heating and cooling system, which uses about 25% of the electricity that traditional heating and air-conditioning systems consume. Several holes were drilled 300 feet deep, where the temperature is a constant 67 degrees. Pipes connected to a heat pump inside the house circulate water into the ground, then back up and through the house, heating it in winter and cooling it in summer. The water for the outdoor pool is heated with the same system
