Why Every Home Needs an Emergency Water Supply

Water is Essential for Survival

Water is your most critical survival need during emergencies. While you can survive weeks without food, you’ll only last about three days without water. During disasters like earthquakes, hurricanes, or infrastructure failures, municipal water systems often become contaminated or completely shut down. Having an independent water supply ensures you can meet your body’s hydration needs, prepare food, maintain hygiene, and provide for pets when normal sources become unavailable.

Disasters Can Strike Without Warning

Natural disasters rarely provide adequate advance notice. Floods, wildfires, and severe storms can develop rapidly, giving you little time to prepare. Infrastructure failures like water main breaks or contamination events can occur without any warning at all. By maintaining a ready emergency water supply, you’re prepared for these unexpected situations rather than scrambling to find water when stores are closed or supplies are depleted.

Water Services Can Be Disrupted for Extended Periods

When disasters strike, water service restoration often takes significantly longer than expected. What might initially seem like a 24-hour outage can extend to days or even weeks in severe cases. FEMA and emergency management experts consistently report that water infrastructure repairs frequently face delays due to extensive damage, parts shortages, or access limitations. Your emergency water tank provides crucial security during these extended disruption periods.

Clean Water Prevents Disease During Emergencies

Disease outbreaks frequently follow disasters due to compromised water systems. Contaminated water can introduce bacteria, viruses, and parasites that cause serious illnesses when safe drinking water isn’t available. Your dedicated emergency water supply, properly stored and maintained, delivers clean water when you need it most, helping prevent waterborne illnesses that could further complicate an already difficult situation.

Peace of Mind is Invaluable

Perhaps the most underrated benefit of maintaining an emergency water supply is the peace of mind it provides. Knowing you’ve taken concrete steps to protect your family’s most essential need delivers tremendous psychological comfort during stressful situations. When emergencies happen, you can focus on other critical concerns rather than worrying about your basic water needs.

Key Features to Look for in Emergency Water Tanks

When selecting water tanks for emergency preparedness, certain features can make the difference between reliable water access and potential problems during critical situations.

Durability and Material Quality

High-Density Polyethylene (HDPE) containers offer superior longevity and safety for emergency water storage. These tanks resist corrosion and don’t leach chemicals into your water supply, making them ideal for long-term storage needs. While stainless steel and glass options provide excellent contamination resistance, they’re typically heavier and less practical for emergency situations. Products like the Reliance Rhino and Scepter containers exemplify the durability standards you should seek.

Storage Capacity and Space Requirements

Your emergency water needs should dictate the tank size you select. For short-term emergencies, 5-10 gallon containers like the Reliance Rhino (5.5 gallons) and Scepter Military Water Can (5 gallons) offer practical portability while providing essential supply. Larger households or extended emergency planning require bigger solutions such as the Surewater 30 Gallon Corner Tank or Bushman 100 Gallon Vertical Tank. Consider both your immediate needs and available storage space when making your selection.

Portability Considerations

Weight becomes a critical factor when evaluating emergency water containers. Even a modest 5-gallon container weighs over 40 pounds when full, making handle design and container profile essential considerations. Slim-profile containers like the Reliance Rhino offer better handling characteristics during transport. For truly portable options, consider the weight when full: Rhino (44 pounds), Scepter Military Can (40 pounds), and Aqua-Tainer (56 pounds). Choose containers that you can realistically manage during stressful situations.

BPA-Free Certification

Always prioritize BPA-free materials for your emergency water storage to prevent potential chemical contamination. BPA (Bisphenol A) can leach into water during long-term storage, potentially causing health concerns during times when medical assistance might be limited. Quality options like the Reliance Rhino and Scepter containers feature BPA-free construction, ensuring your emergency water supply remains as pure and safe as possible throughout extended storage periods.

How Much Water Should You Store for Emergencies

The general recommendation for emergency water storage is at least one gallon per person per day. This amount covers drinking, cooking, and basic hygiene needs during a crisis situation. For a comprehensive emergency plan, you should aim to store enough water for at least two weeks.

For a single person, this means storing a minimum of 14 gallons for a two-week emergency supply. A family of four would need at least 56 gallons of water to meet their basic needs during the same period. These calculations provide a baseline, but consider adding extra capacity for pets, medical needs, or extreme weather conditions.

When planning your water storage, remember that emergencies can last longer than anticipated. Infrastructure repairs following major disasters often face unexpected delays, making a generous water supply a crucial part of your emergency preparedness strategy. Proper storage containers like those mentioned earlier will help maintain water quality throughout the storage period.

Proper Maintenance of Emergency Water Tanks

Safety Precautions

Always use food-grade containers for your emergency water storage to prevent harmful chemicals from leaching into your water supply. These containers are specifically designed to maintain water quality without contamination. Store your water tanks in a cool, dark location away from direct sunlight, as UV rays can degrade plastic containers and promote algae or bacterial growth.

Cleaning and Sanitizing

Thorough sanitization is essential before filling your emergency water tanks. Mix 1 teaspoon of unscented liquid household chlorine bleach with 1 quart of water to create an effective sanitizing solution. Scrub the interior surfaces completely, then rinse with clean water until no bleach odor remains. For large tanks, you may need to scale up the solution while maintaining the same ratio.

Storage

Proper storage location significantly impacts water quality and container longevity. Keep your tanks away from chemicals, gasoline, pesticides, and other potential contaminants that could leak or produce fumes. A temperature-controlled environment between 50-70°F is ideal for maintaining water quality and preventing container degradation over time.

Inspection and Rotation

Mark your containers with the filling date using a waterproof marker or label system. Inspect your water storage tanks quarterly for cracks, leaks, or unusual odors that might indicate contamination. Replace stored water every 6-12 months, depending on storage conditions and container quality. Scepter and WaterBrick containers generally maintain water quality longer due to their superior materials.

Sealing and Portability

Ensure all caps and spouts are tightly sealed to prevent airborne contamination and possible leakage. Test the seals periodically by tipping containers slightly to check for leaks. For containers like the Reliance Rhino or Aqua-Tainer, verify that the spigots are properly closed and sealed. Consider organizing your containers so that the most easily accessible ones are rotated first during your maintenance schedule.

Conclusion: Ensuring Your Family’s Water Security

Selecting the right emergency water tank is a crucial investment in your family’s safety and peace of mind. Whether you opt for the portable Reliance Aqua-Tainer the substantial WaterPrepared 160-Gallon tank or one of the other recommended options you’re taking a vital step toward comprehensive emergency preparedness.

Remember that proper maintenance including regular cleaning sanitization and rotation of your water supply will ensure it’s ready when you need it most. By considering factors like capacity durability and material safety you can find the perfect solution for your household’s specific needs.

Don’t wait for disaster to strike. With your new emergency water tank properly maintained and readily accessible you’ll have one less worry during challenging times letting you focus on what matters most—keeping your family safe and healthy.
