Don't be a Water Waster!

Follow these tips and help to save hundreds of gallons of water! 

  • Install a low-flow showerhead, then take only 5-minute showers or 3-inch baths.
  • Install a 1.28 gallon high efficiency toilet, which can save 52 gallons per day.
  • Catch water in a bucket or watering can while waiting for it to get hot. Then use it on plants, or pour into toilet bowl to flush.
  • Fix all leaky toilets, faucets, and pipes.
  • Do not use the toilet to flush trash.
  • Turn off the water when shaving, brushing teeth, lathering in the shower, washing dishes, or cleaning produce.
  • Run only full loads in dishwashers and washing machines.
  • Water your lawn no more than once a week, and operate automatic sprinklers manually. Water outdoors in the early morning or evening.
  • Use a bucket, sponge, and a hose with a shut-off valve, to wash your car.
  • Sweep (never hose) your driveway, patio and sidewalk.
