Water system #1 collects rain water from the downspout and directs it immediately into the Self-Watering Garden to the left and then into the irrigation system that leads to the three Garden Cubes in front. Because it goes directly to the gardens it does not require a large holding tank. The system can be switched over to tap water if there is not enough rain.
Water system #2 is a large collection system that will hold 2,000 litres of water. The tanks fill up in the rainy season and lead to the gardens by irrigation lines and water the gardens throughout the hot, dry summer.
