Use a shut-off spray nozzle on your hose to wash the car.
Clean driveways, patios and decks with a broom instead of a hose.
Check for leaks around the house, including dripping faucets, running noise in toilet, etc. A drip can waste as much as 5,000 gallons per month. To check for leaks turn everything off that uses water. Check your water meter and write down the current reading (include tenths of a cubic foot). Then check the meter again after one hour. If the meter has changed you have a leak.
Consider installing water efficient plumbing fixtures.
Toilets installed before 1993 generally use 2 to 4 times more water then newer toilets. These can either be replaced or a glass quart jar without a lid may be placed in the tank.
Keep a jug of drinking water in the refrigerator instead of running tap water until cold.
