Store a two-week supply -- at least one gallon per person per day.
After a storm, don't drink tap water until you know it is safe. If a "Boil Water Order'' is issued, the media will announce it.
Store water only in clean containers and only for three months. Bottled water generally should be stored only for six months.
You can store water in your bathtub for flushing toilets and washing -- not drinking. Sponge the tub with a solution of liquid bleach and water, caulk the drain to make it watertight, and fill. Cover it if you can. Use four drops of unscented bleach per gallon of water.
Freeze as much water as you can.
Before a storm, shut off your water heater from its water source so it will not get contaminated.
You can bottle water in food-grade plastic containers. Wait until a hurricane warning is announced to do it.
Boiling water at a rolling boil for one minute will kill infectious organisms. Let it cool, and store in clean containers. If water is cloudy, filter it through clean cloths or allow it to settle, and draw off the clear water for boiling.
If you can't boil water, then disinfect it using household bleach. Bleach will kill some, but not all, types of disease-causing organisms. Add 1/8 teaspoon (or eight drops) of regular, unscented household bleach per gallon of water, stir it well and let it stand for 30 minutes before using.
