Recommendations to conserve water are:
Use dishwashers only when they are full. Washing dishes by hand (don’t let the tap run!) saves about twenty-five (25) gallons.
Adjust water level on clothes washing machines, if possible. Use full load only, of not adjustable.
Turn off faucets while brushing teeth, etc. saves about five (5) gallons per day.
Reduce water used per flush by installing toilet tank displacement inserts. A plastic jug may often be used as an alternative. DO NOT USE BRICKS—they disintegrate when soaked and the resulting grit hinders closing of the flap valve.
Do not use the toilet as a trash can.
Use sink and tub stoppers to avoid wasting water.
Keep a bottle of chilled water in the refrigerator for drinking.
Find and fix leaks in faucets and water using appliances. Faucets can usually be fixed cheaply and quickly by replacing washers.
Learn to read your water meter so you can judge how much water you use and what difference conservation makes.
Take shorter showers and shallow baths — saves about twenty-five (25) gallons.
Reduce the number of toilet flushes per day. Each flush uses about five (5) gallons (two to three gallons, if you have water saving toilets).
Don’t use a garbage disposal.
Use non-phosphate detergent and save laundry water for lawns and plants.
