Rainwater Harvesting: Harvesting rainwater reduces the use of drinking water for landscape irrigation. It is also an effective water conservation tool and proves more beneficial when coupled with the use of native, low water-use and desert-adapted plants. Additionally, rainwater is available free of charge and puts no added strain on the municipal supply or private wells.

Gray Water Harvesting: Gray water is defined as wastewater, collected separately from sewage flow that originates from a clothes washer, bathtub, shower or sink, but not from a kitchen sink, dishwasher or toilet. In general, gray water is an excellent source of water for household gardening, composting, and landscape irrigation. Gray water must be used so that it does not run off your own property.
