Desert Botanical Garden: THE DESERT HOUSE: Saving Water

Homeowners can make a drastic reduction in outdoor water use by replacing grass lawns with low water use plants. Lawn irrigation can account for 50% of water consumed by residential users. A list of low water use plants suitable for the Phoenix area can be obtained from the Desert Botanical Garden or the Water Conservation Office of each Valley city. All of the plants listed are readily available at local nurseries.

All plants require water in order to grow and thrive. Delivering water efficiently to plants through a drip irrigation system and contouring the landscape to direct rainfall runoff to certain plants will alleviate some of the demand. Generous use of mulches around plants to decrease the amount of water lost to evaporation helps control water use. Irrigate plants in the evenings or early mornings, when temperatures are cool and the sun is low to save water. Use timers or irrigation control clocks to control over and under watering, and to water at times not convenient to gardeners, such as before dawn.

Inside water use can be reduced by installing low flow faucets, shower heads, and toilets. Older toilets can be retrofitted easily with low flush kits. These are available at most hardware and home improvement stores. Low flow faucets and aerators, in all price ranges, are found in most hardware stores and are easy to install.

Another simple way to save water is to turn off the flow when not actually using the water. While brushing teeth, bathing or washing dishes, turn off the water until it is needed. Wash only full loads in dishwashers and washing machines. Avoid using water to clean off sidewalks and patios; sweeping can accomplish the same result.
