How to Choose the Right 5 Gallon Water Storage Tank
Selecting the best tank for your needs involves considering a few important factors:
1. Intended Purpose
- Emergency/Long-Term Storage: Look for food-grade, BPA-free, stackable options with durable handles, tight sealing caps, and features for easy pouring.
- Outdoor/Camping Use: Consider models with robust handles, lighter weight, and optional accessories like spouts or shower hoses.
- Home/Garden Use: Tanks with wide mouths for easy filling, draining, and cleaning, as well as UV-resistant plastics.
2. Material and Safety
- Always select containers made from “food-grade” plastics if you plan to store drinking water.

4. Handling and Portability
- Look for large, comfortable handles built into the tank for easy transport.
- Rounded corners and ergonomic designs further aid in lifting and moving.
5. Spigot and Cap Design
- Some tanks offer spigots or faucets directly on the container for easy dispensing.
- Vent caps make pouring smoother and reduce “glugging.”
6. Ease of Maintenance
- Wide-mouthed designs make for simple, regular cleaning.
- Consider if replacement parts (like gaskets or spigots) are available.
7. Cost and Value
- Expect to pay more for stackable, premium, or accessory-enhanced models. However, the durability and user-friendly features usually add value over the long term.
- Buying in sets or bundles can lower the overall unit price and improve flexibility.
User Tips and Best Practices
Storing Water Safely
- Clean Containers Before Filling: Use unscented bleach (1 tsp per quart of water) to sanitize, then rinse thoroughly.
- Fill with Potable Water Only: Always use treated municipal water, or purify well/stream sources before filling.
- Label and Date: Mark the fill date on each tank using a waterproof marker for easy rotation.
- Store Upright in a Cool, Dark Place: This prevents stacking stress, UV degradation, and limits algae growth.
- Seal Tightly: Ensure caps and vent seals are fully closed after filling to keep contaminants and pests out.
Water Rotation & Shelf Life
- For municipal tap water in food-grade containers, rotate every 6–12 months.
- Purified water with added chlorine can last longer but regular rotation is safest practice.
- If storing for emergencies, keep some water treatment chemicals on hand (tablets, drops, or purifiers).
Cleaning and Maintenance
- At least once per year, empty and deeply clean each container. Use a solution of unscented bleach and water, brush any residue, and thoroughly rinse.
- Allow to dry before refilling.
Smart Usage
- Assign one or two containers for daily/short-term needs; use others only in emergencies.
- Use portable tanks for travel, camping, or evacuation scenarios.
- Keep a spigot or pump accessory with your storage tanks for convenient pouring.
Transportation
- Don’t overfill—allow a small air gap to account for water expansion if stored in heat.
- If moving full tanks in vehicles, secure them to prevent tip-overs and spills.

FAQ
What is the shelf life of water stored in a 5 gallon tank?
Water stored in a food-grade, BPA-free tank in a cool, dark place can remain good for 6–12 months. It’s best practice to replace or rotate every six months for highest quality, especially for drinking water.
Do I need to add any chemicals to stored tap water?
Municipal tap water generally does not require additives if stored in a clean, food-grade container. For well or creek water, or if the source quality is uncertain, add chlorine bleach (unscented, household) at 1/8 teaspoon per gallon as a backup.
Can I stack any 5 gallon water tanks?
Only stack models specifically designed for stacking. These have reinforced lids, interlocking surfaces, or modular shapes. Stacking non-stackables risks collapse or leaks.
Are all 5 gallon water tanks food safe?
Not all; ensure your container is labeled “food grade” and “BPA-free” if you’re storing drinking water. Containers not intended for potable storage may leach harmful chemicals.
How do I clean and maintain my water storage tank?
Rinse first, then wash with a solution of 1 tsp unscented bleach per quart of water. Scrub all interior surfaces, rinse thoroughly, and air-dry before filling.
How much does a full 5 gallon water tank weigh?
A full 5 gallon tank weighs about 40 pounds (18 kg). Ensure you are physically able to lift and carry this weight before filling to capacity.
Can I freeze water in a 5 gallon storage tank?
It’s not recommended. Water expands as it freezes, which can crack plastic tanks. If storing in cold climates, leave space for expansion, or keep tanks in temperature-controlled areas.
What is the difference between blue and clear/white tanks?
Blue and dark-colored tanks prevent light from entering, reducing algae and bacteria growth, thereby keeping water fresh longer. Clear or white tanks allow light in, potentially compromising water quality over time.
Is it safe to reuse other plastic containers for water storage?
Generally, only reuse containers originally designed for food or drink. Never use containers that once held non-food substances (chemicals, detergents) for water storage, as plastic can retain dangerous residues.
Can I transport 5 gallon tanks in my car or RV?
Yes, these tanks are designed for transport—just ensure they are sealed tightly and secured to avoid spills or tipping while driving.
