How to Be Prepared for a Flood
By Nate BakerFloods are one of the most common and destructive natural disasters. They can occur with little warning due to heavy rain, flash flooding, storm surge, or infrastructure failures. Knowing how to be prepared for a flood can protect your family, your home, and your access to clean drinking water when it matters most.
Understand Your Flood Risk
Preparation starts with awareness. Flood risk isn’t limited to coastal areas—flooding can happen anywhere.
- Check local flood maps and flood zones
- Know if you live near rivers, washes, or low-lying areas
- Understand the difference between river floods and flash floods
Even areas that rarely flood can be cut off from utilities, roads, and clean water during major storms.
Create a Flood Emergency Plan
A clear plan reduces panic and confusion.
- Identify evacuation routes and higher ground
- Choose a family meeting location
- Plan for pets and livestock
- Store emergency contact numbers offline
Practice your plan, so everyone knows what to do if flooding occurs at night or on short notice.
Build a Flood Emergency Kit
Your emergency kit should support your household for at least 72 hours.
- Non-perishable food
- Flashlights and batteries
- First aid supplies (get a good kit).
- Essential documents in waterproof bags
- Protective gloves and boots
Store Enough Emergency Water
Floods frequently contaminate municipal water supplies. Sewage overflow, chemicals, and debris can make tap water unsafe to drink.
Emergency water storage is one of the most critical flood preparedness steps:
- Store at least 1 gallon per person per day, but we recommend more.
- Plan for 3–7 days of water minimum (again, that is the bare minimum).
- Use food-grade, sealed water storage containers designed for long-term storage.
Durable, rotationally molded water tanks provide a reliable source of clean water even if plumbing systems fail or boil notices are issued.
- Compact stackable water tank (30-gallon capacity)
- Large stackable water tank (55-gallon capacity)
- Doorway water tank (300-gallon capacity)
Prepare Your Home Before Flooding Starts
Taking action early can significantly reduce damage.
- Move valuables and electronics to higher levels
- Install backflow valves if possible
- Clear gutters and drainage paths
- Anchor or elevate large water storage tanks
If flooding is imminent, turn off electricity and gas only if it is safe to do so.
Know What to Do During a Flood
- Never walk or drive through floodwater
- Move to higher ground immediately
- Follow evacuation orders without delay
- Avoid contact with floodwater whenever possible
Just a few inches of fast-moving water can knock a person off their feet, and floodwater often contains dangerous contaminants.
After the Flood: Stay Safe
Flood risks don’t end when the water recedes.
- Do not drink tap water until declared safe
- Use stored emergency water for drinking and cooking
- Avoid damaged structures until inspected
- Wear protective gear during cleanup
This is where having your own emergency water supply becomes invaluable.
Why Water Storage Is Essential for Flood Preparedness
Floods are one of the most common causes of long-term water outages. Roads may be impassable, bottled water may be unavailable, and municipal systems can take days or weeks to recover.
Having properly stored emergency water ensures:
- Safe drinking water when supplies are contaminated
- Water for cooking, hygiene, and sanitation
- Independence during extended recovery periods
Preparedness isn’t just about surviving the storm—it’s about maintaining stability afterward.
Frequently Asked Questions About Flood Preparedness
How much water should I store for a flood?
Plan for at least one gallon per person per day for 3–7 days. More is recommended if you have pets or live in a high-risk area.
Can I rely on bottled water?
Bottled water sells out quickly before floods and may be unavailable afterward. Long-term water storage tanks provide far more reliability.
Is floodwater safe to use for anything?
No. Floodwater is often contaminated with sewage, chemicals, and debris and should be avoided.
Be Ready Before the Water Rises
Flood preparation is about planning ahead—before warnings are issued and shelves are empty. By understanding your risk, building an emergency plan, and storing clean drinking water, you can protect your household from one of nature’s most unpredictable disasters.
Preparedness starts now—not when the water is already at your door.
