Emergency Preparedness

Do you have enough water in the event of an earthquake?

Keep a three-day water supply just in case.

    • Each family member (including pets) needs one gallon per day

    • Store tap water in food-grade plastic containers; replace every six months

    • Store bottled water in the original sealed containers; replace every six months.

If your supply runs out, you can treat your tap water.

    • Boil it for three minutes, or disinfect it by adding regular household bleach

    • Add eight drops of bleach for every gallon of water

    • Shake or stir then let it stand for thirty minutes.
