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 it into the 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.
