Water Conservation Tips

All Around the House

  • Check every faucet for leaks. Just a slow drip can waste 15 to 20 gallons a day.
  • Use a broom, not the hose, to clean the garage, sidewalks, and driveway.
  • Wash the car from a bucket. Use the hose only to rinse it off afterwards.
  • Insulate the hot water heater, pay special attention to the insulation qualities of the shell. Avoid buying a larger tank than necessary for your needs.


  • Remove frozen foods from freezer before you're ready to use them so you won't have to use running water to hasten thawing.
  • Always use lids on pot and pans.
  • Use the smallest amount of water possible in cooking to save both water and nutrients. Most frozen vegetables require about 1/2 to 1 cup of water, not half a saucepan.
  • Rather than letting the water run while peeling vegetables, rinse them briefly at the beginning and end of the chore.
  • Don't let the faucet run for a cold drink. Keep a jug of water cooling in the refrigerator.
  • When washing dishes by hand, use a stopper in the sink and don't rinse with running water.
  • Use low sudsing detergents - they require less rinsing.
  • Adding 1/4 to 1/2 cup of vinegar to your wash water cuts grease more readily than hot water alone.
  • Run your dishwasher only when you have a full load, since each load uses from 12 to 17 gallons of water.
  • Use the pre-wash, rinse-hold and scrub cycles of your dishwasher only when necessary.


  • If your washer has a variable load control, always adjust water levels to fit the size of the load. This saves both water and the energy needed to heat the extra hot water.
  • Run your washer when you have a full load.
  • Remember that in soft water clothes get cleaner and require less detergent and less rinse water.
  • When buying a new washing machine, look for models with water or energy-saving controls.


  • Don't leave water running while washing your face, shaving or brushing your teeth.
  • An electric razor uses less energy than it takes to heat up water for razor shaving.
  • Your toilet is not a wastebasket - don't use it to flush away cigarette butts or kleenex.
  • Toilet dams save about two gallons per flush.
  • Most new toilets are engineered for low volume and use about 3-1/2 gallons per flush.
  • Put a few drops of food coloring in your tank. If colored water shows in the bowl without flushing, there's a leak and repairs are needed.
  • A shower generally uses less water than a bath.
  • Do your showering and hair washing in one step.
  • Fill the tub on 1/4 full. This is enough to cover an adult's body or float a child's toy.
  • Most showers can be fitted with a flow restrictor or low-volume head to conserve water.
  • Don't turn the shower on until you're ready to step in.

Outdoor Use

  • Morning is the best time to water lawns. Before 10 a.m. is best of all because rising heat later on tends to steal a lot of water by evaporation. (See Watering restrictions above.)
  • A lush green lawn requires 1 to 1-1/2 inches of water a week. Water three times a week applying about 1/2 inch at a time. Keep in mind the amount of rainfall and adjust your watering schedule accordingly.
  • If you let your grass grow to about 1-1/2 to 2 inches in the summer, water loss will be reduced because the blades will provide shade for the roots.
  • Lawns that are frequently aerated absorb water better.
  • Thatch build-up in a lawn can create a rapid run-off situation. Every spring the lawn should be raked and dead grass removed.
  • Sprinklers throwing large drops in a flat pattern are more effective than those with fine, high sprays.
  • Forget about watering streets, walks and driveways. They don't grow a thing.
  • Mulch shrubs and other plantings so the soil holds moisture longer.
  • When possible, flood irrigate vegetables and flower gardens rather than using sprinklers. Irrigation allows deeper soaking with less water. Sprinklers result in high evaporation loss of water.
