Lawn watering — Water in the early morning or late evening when evaporation rates are lowest. Don’t water the pavement! One inch of water per week is all that is generally necessary to maintain your lawn. Avoid over-watering by using a rain gauge or coffee can to measure the volume of water being applied. As a general rule, lawns only need watering every five to seven days in the summer and every 10 to 14 days in the winter. A hearty rain eliminates the need for watering for as long as two weeks.
Periodically monitor your watering (especially automatic sprinklers) to ensure there aren't any leaks. This will also ensure that your grass, trees and plants are getting the water you intended.
Lawn care — Allow your grass to grow taller in hot, dry weather. Longer grass means less evaporation and will encourage roots to grow deeper, leaving your lawn more drought-tolerant.
Car washing — Use a bucket to wash. Keep a shut off nozzle on the end of your hose to turn off water when not using it. Do not let water run when not in use!
Pool — Use a pool cover to keep water clean and reduce evaporation.
General Maintenance — Use a broom instead of a water hose to clear debris from patios, driveways, and/or sidewalks.
Landscaping — Plant trees to provide shade and decrease lawn area. Use drought-resistant shrubs and plants. Use decorative rock or landscaping bricks to decorate areas instead of plants that require a lot of water.
Valves, Sprinklers, Hoses, Bibs, Outdoor Pipes — Check all your outdoor water sources for leaks on a regular basis, leaks can occur overnight. Don't forget to wrap your exposed pipes, etc. to avoid freezing and bursting.
