The Essential Guide to Buying the Right Water Storage
Having reliable water storage is a smart move. Whether you are preparing for emergencies, setting up an off-grid system, or just need extra water for your garden, choosing the right container matters. This guide helps you pick the best water storage for your needs.
Key Features to Look For
When shopping for water storage, several features make a big difference in how useful and safe the tank is.
Capacity and Size
- How Much Do You Need? Think about how much water you need daily. A good rule is to store at least one gallon per person, per day, for several days.
- Space Matters: Measure the space where you plan to put the tank. Tall, narrow tanks fit better in small corners, while large, squat tanks offer more volume.
Durability and Lifespan
- Wall Thickness: Thicker walls mean the tank resists punctures and bulging better. Heavy-duty tanks last much longer.
- UV Protection: If your tank sits outside, it must have UV inhibitors. Sunlight breaks down weak plastics quickly, making them brittle.
Ease of Use
- Access Points: Look for large openings for easy cleaning. You must be able to get a brush inside!
- Spigots and Outlets: Check the quality of the valves or spigots. Brass or high-quality plastic fittings resist leaks better than cheap ones.
Important Materials for Water Storage
The material of your water tank affects its safety, cost, and longevity.
Plastic (Polyethylene)
Most common water tanks use food-grade polyethylene (PE). This plastic is generally safe and affordable.
- HDPE (High-Density Polyethylene): This is the standard. It is strong and resists many chemicals.
- Color is Key: Always choose opaque (not see-through) containers. Clear containers allow light in, which causes algae growth. Dark blue or black tanks are usually best for outdoor use.
Metal (Stainless Steel or Galvanized Steel)
Metal tanks are very durable and often used for large volumes or pressurized systems.
- Stainless Steel: This is the highest quality. It does not rust and is very easy to keep clean. It is also the most expensive option.
- Galvanized Steel: This is cheaper than stainless steel, but the zinc coating can wear off over time, potentially affecting water quality if not properly maintained.
Factors That Improve or Reduce Quality
The quality of your stored water relies heavily on the container itself and how you treat it.
Quality Enhancers
- BPA-Free Certification: If you use plastic, ensure it is certified BPA-free, especially if you plan to drink the stored water.
- Seam Integrity: Tanks made from a single piece (seamless) are stronger than tanks assembled from multiple welded pieces.
Quality Reducers
- Recycled Plastics: Avoid plastics of unknown origin. Recycled materials might contain harmful residues.
- Poor Sealing: Any tank that does not seal tightly allows dust, insects, and contaminants to enter the water supply.
User Experience and Use Cases
How you plan to use the water storage will determine the best style.
Emergency Preparedness (Indoor Use)
For earthquake or storm readiness, portability and stackability are important. Smaller, sturdy plastic containers (like 5- to 7-gallon jugs) are often preferred because they can be moved easily and stored in closets.
Gardening and Rainwater Harvesting (Outdoor Use)
For large volumes needed for irrigation, large cisterns or rain barrels are necessary. These should be opaque, have a sturdy base to handle the immense weight of the water, and include a screen on the inlet to keep out debris.
Off-Grid Living
People living completely off the grid often need huge, permanent tanks (500 gallons or more). These must be installed professionally on concrete pads. The material choice here often leans toward durable polyethylene or large stainless steel tanks.
Water Storage Buying Guide FAQ
Q: Should I store water treated with bleach?
A: Yes, for long-term storage (over six months), adding a small amount of unscented household bleach can help keep the water safe from bacteria. Always follow recommended guidelines for the amount of bleach used.
Q: How often do I need to clean my water storage tank?
A: You should completely empty, scrub, and refill your tank at least once every 6 to 12 months. If the water smells strange or looks cloudy, clean it immediately.
Q: Is it safe to store hot water in a plastic tank?
A: No. Most standard food-grade plastic tanks are not rated for high temperatures. Storing very hot water can warp the plastic and potentially release chemicals. Use specialized insulated metal tanks for hot water storage.
Q: What is the main difference between an IBC tote and a standard barrel?
A: An IBC (Intermediate Bulk Container) tote holds much more—usually 275 gallons—and is often square, making it efficient for space. A standard barrel usually holds 55 gallons and is round.
Q: Can I connect my water storage tank directly to my home plumbing?
A: You can connect it to a low-pressure system using gravity feed, but for high-pressure needs (like running showers), you will need a separate water pump installed after the tank.
Q: Why are black tanks sometimes better than blue tanks outside?
A: Black tanks absorb slightly more heat, which can help prevent freezing in very mild cold snaps. However, both black and dark blue tanks effectively block the light needed for algae growth.
Q: Does the color of the plastic matter for drinking water?
A: Yes. The color must be opaque (not see-through). If light gets in, algae will grow, contaminating your drinking supply.
Q: Are used food-grade barrels safe for water storage?
A: Used food-grade barrels are often safe, but you must thoroughly clean them first. Make sure they only held food products (like pickles or syrups) and never hazardous chemicals.
Q: How much does 50 gallons of water weigh?
A: Since one gallon of water weighs about 8.34 pounds, 50 gallons weighs approximately 417 pounds. Always ensure your floor or stand can support this weight!
Q: What is the best way to keep my stored water fresh without chemicals?
A: The best way is to rotate your supply. Use the stored water every six months, and then refill the tank with fresh tap water. This ensures you always have the freshest possible supply.
