Natural Disaster – Water Tips


  1. Because you might lose water supply during a hurricane, you are advised to save an adequate supply of water for domestic use. 
  2. Store water in properly sanitized bathtubs or containers. 
  3. Boil water that has been stored for several days for at least two minutes to ensure that pollutants are destroyed prior to use. 
  4. Listen to the radio for an announcement from the Department of Environmental Health Services or the Water and Sewerage Corporation in the event the municipal supply becomes unsafe for domestic use. 
  5. Flooding increases the possibility of private well contamination. Residents using private well systems are advised not to use the water for potable purposes. Wait for the Department of Environmental Health Services to advise on chlorination treatment.


Clean water is an essential part of your emergency supplies kit. You will need water for drinking, preparing food, and taking care of sanitary requirements. Follow these simple guidelines:

  1. Determine your water needs
  • Allocate at least 1 gallon of water per person per day for drinking and sanitation.
  • Store a three day supply for each person – so at least 3 gallons per person. 
  • Children, nursing mothers and sick persons may need more. People also drink more in extreme heat.
  • Don’t forget your pets! A dog needs ½ gallon of water per day.
  1. Store water in a clean container
  • Use plastic water or soda bottles. Bottles that contained milk or fruit juices tend to promote bacterial growth.
  • How about a bathtub?  A bathtub holds enough water for 4 people for 3 days.
  • Thoroughly clean and rinse containers before filling them.
  • If you are filling containers from a private well water supply, add plain liquid bleach to kill germs.  Add 16 drops (1/2 ml) to 1 gallon, or ½ teaspoon to 5 gallons of water.
  • Commercially bottled water is a good alternative for your drinking water supply.  Keep the water in the original bottle, and do not open until you need to use it.
  1. Things to remember
  • Boil water before using, if it has been stored for several days.
  • Your emergency supplies kit should include hand sanitizer, moist towelettes, garbage bags and plastic ties for sanitation and personal hygiene needs.  This reduces water usage.
  • Stock a 3-day supply of  non-perishable, easy to prepare foods, preferably those that do not require adding water for preparation – e.g. some soups.
  • Before a storm, check the shut-off valve for the water line that enters your home.  Make sure the valve can be completely shut off in the event of a broken pipe.
  • Listen to official alerts for latest updates, and follow their instructions.
  1. If you normally use a private well supply
  • You should always maintain access to the city water supply, especially when preparing for a hurricane! Get connected today!
  • Flooding during and after a hurricane makes well water extremely unsafe because pollutants including raw sewage, chemicals and microorganisms can contaminate wells, especially in populated areas.
