Outside the house, water thoroughly but less frequently and only in the cool times of day. Turn off your automatic sprinklers when it rains. Water your lawn only when it needs it; if a screwdriver inserted into the soil goes in seven inches easily, the lawn doesn’t need water. Don’t let the hose run while washing your car; use a bucket instead with a quick hose rinse at the end. Use a broom instead of a hose to clean driveways and sidewalks.
Inside the house, run only full loads in your washing machine and dishwasher. Refrain from using your toilet as a wastebasket. Turn the water off while brushing your teeth and shaving. While waiting for hot water to come down the pipes, capture the cold water in a watering can to use later on your plants. Shorten your showers, or install a low-flow showerhead.
