If you have  NO WATER

If you have exhausted your water supplies and have a well, you can follow some water purification procedures until water service is restored.
Contaminated water can contain microorganisms that cause disease. You should purify any water of which you're uncertain. There are many ways to purify water; none are perfect. Often the best solution is a combination of methods.

Your hot water heater is another source of usable water.
The hot water heater should be shut off, the inlet valve closed and drained of sediment (until water runs clear) and then refilled (opening inlet valve again). If you use this source of water and your electricity is off, turn off the circuit breaker so the heating elements don't burn out when power is restored.

Before purifying, let any suspended particles settle to the bottom, or strain them through layers of clean cloth.

The following are three purification methods, all of which kill microbes:

BOILING is the safest way to purify water. Bring water to a rolling boil for 10 minutes, keeping in mind that some water will evaporate. Of course, let cool before drinking. Boiled water will taste better if you put oxygen back into it. Do this by pouring water back and forth between 2 clean containers. This also will improve the taste of stored water.

CHLORINATION uses pure, unscented, liquid chlorine bleach to kill microorganisms in water. Add 2 drops of bleach per quart of water (4 drops if the water is cloudy), stir and let stand for 30 minutes. If the water does not smell or taste of chlorine at that point add another 2 drops and let stand for 15 minutes.

PURIFICATION TABLETS release chlorine and iodine into the water. They are inexpensive and are available at most sporting goods stores and some drug stores. Follow the package directions. Usually 1 tablet is enough for 1 quart of water. Double the dose for cloudy water.
