Boil Notice Issued? Securing Potable Household Water
Water is the first and most critical survival requirement. When a city main ruptures or floodwaters contaminate reservoirs, drinking tap water can introduce bacteria, cryptosporidium, and heavy chemicals.
Quick Checklist
- Bring water to a vigorous rolling boil for 1 full minute (3 minutes at elevations above 5,000 ft).
- Do not use tap water to brush teeth, wash dishes, or prepare baby formula.
- Rely on your sealed, pre-stored 5-gallon water jugs first before filtering suspect water.
- Use certified hollow-fiber filters (0.1 micron) or purification tablets as backup.
- Shut off the water main into your home to protect your water heater tank reservoir.
Phased Action Plan
Hidden Water Source: Your Water Heater
Turn off power/gas to your tank heater. You now have 40 to 50 gallons of clean potable water stored inside your basement tank accessible via the drain valve.
