Avoid overfertilizing your lawn. The application of fertilizers increases the need for water. Mulch to retain moisture in the soil. Mulching also helps to control weeds that compete with pants for water. Once established, they do not need to be watered as frequently and they usually will survive a dry period without any watering.
Group plans together based on similar water needs.
Do not hose down your driveway or sidewalk. Use a broom to clean leaves and other debris from these areas. Using a hose to clean a driveway can waste hundreds of gallons of water. Outfit your hose with a shut-off nozzle which can be adjusted down to fine spray so that water flows only as needed. Use hose washers between spigots and water hoses to eliminate leaks.
