Water and electricity at the Bioshelter/farm
We supplement our water supply using a roof-catch cistern system with a 15,000-gallon capacity, but due to lack of precipitation we use mostly city water. In the Bioshelter, for most plant watering, we use warmed rainwater/city-water applied through a gravity-fed hose or watering can. For landscape watering, we supplement with gray water, which we store in a tank. The Bioshelter’s indoor water-storage tanks have a capacity of 1,300 gallons.

To heat our water, we use a solar system, along with a backup propane on-demand water heater. We run pumps, lights, fans a refrigerator and power tools with photovoltaics. Our 1600 watt grid-tied photovoltaic systems more than meets our needs. Wind generation is prohibited by the large pine trees around the property.
