This guide will teach the reader how to evaluate existing household containers, sanitize them, and convert them into dependable emergency water storage units. By following the procedures outlined below, the reader will be able to create a resilient water supply that can sustain a family for several days without relying on costly bottled water. The information presented is based on industry‑standard sanitation practices and real‑world product performance data. The reader will also discover which commercially available tools simplify each step, while still being able to complete the project using only basic household items if desired. ## What You’ll Need - Cleaning agents (unscented bleach, food‑grade detergent) - Soft scrub brushes and non‑abrasive sponges - Food‑grade [water](#)‑tight liners or containers (see product recommendations) - Hand pump or siphon for water extraction - Measuring cup for chlorine dosing - Labels and permanent marker for dating water - Optional: hose adapters, overflow valves, and stands for larger barrels ## Step 1: Assess Existing Containers Begin by cataloguing every container that could potentially hold water. Common candidates include bathtubs, utility sinks, large plastic barrels, and stackable water jugs. Verify that each container is structurally sound, free of cracks, and constructed from materials that will not leach harmful chemicals into drinking water. For example, containers made from BPA‑free high‑density polyethylene are ideal because they resist degradation under ultraviolet exposure. When the reader identifies a bathtub as a viable option, the [waterBOB Emergency Water Bladder](https://amazon.com/dp/B001AXLUX2?tag=wpem020126-20) provides a patented, food‑grade liner that transforms the tub into a 100‑gallon sealed reservoir. This product eliminates the need to purchase bulky drums and reduces the footprint of stored water when the emergency period ends. If the household already possesses a sturdy outdoor barrel, the [RTS Home Accents 50‑Gallon Rain Barrel](https://amazon.com/dp/B00YFT9846?tag=wpem020126-20) can be repurposed for rainwater capture and later treated for potable use. The flat‑back design allows placement against a wall, conserving yard space. For compact indoor storage, the [Reliance Aqua Tainer 7‑Gallon 4‑Pack](https://amazon.com/dp/B07PBCJTLW?tag=wpem020126-20) offers stackable, rigid containers that fit under a kitchen counter or in a closet, providing immediate access to treated water. Finally, for large‑scale, long‑term storage, the [HOANK 55‑Gallon Water Barrel](https://amazon.com/dp/B0FHSQ12HJ?tag=wpem020126-20) delivers industrial‑grade capacity with dual fittings for versatile pump connections. ## Step 2: Clean and Sanitize the Container Thorough cleaning is essential to prevent microbial growth and to remove residues that could affect taste. Begin by rinsing the container with warm water to eliminate loose debris. Apply a solution of one tablespoon of unscented household bleach per gallon of water, ensuring the mixture contacts all interior surfaces. Allow the solution to sit for at least five minutes, then scrub with a soft brush to dislodge stubborn grime. After scrubbing, rinse the container repeatedly with clean water until the chlorine odor disappears. For containers that will be sealed, such as the waterBOB liner, perform a final rinse and allow the interior to air‑dry completely before installation. This step prevents dilution of the chlorine dose when the water is later added. When using the RTS Rain Barrel outdoors, consider installing a fine mesh screen over the inlet to keep insects and leaf litter out during the cleaning process. The screen can be removed after the barrel is filled and the water is filtered. For the Aqua Tainer jugs, the built‑in screw‑on vent simplifies venting air during rinsing, reducing the risk of trapped moisture that could foster mold. ## Step 3: Choose the Appropriate Storage Solution The decision matrix for selecting a storage method depends on three factors: available space, desired capacity, and intended use. The waterBOB Emergency Water Bladder is optimal for households that have a bathtub but limited floor space. Its 100‑gallon capacity provides enough water for a family of four for up to ten days, assuming a consumption rate of one gallon per person per day. Key features of the waterBOB include a sealed food‑grade liner that keeps water fresh for up to sixteen weeks, a hand‑pump siphon for easy dispensing, and a setup time of roughly twenty minutes without permanent modifications. The product is priced at $34.94 and holds a rating of 4.7 stars from 5,393 reviews, indicating strong consumer confidence. If the reader prefers an outdoor, rain‑water harvesting system, the RTS 50‑Gallon Rain Barrel offers UV‑resistant recycled plastic construction, an overflow valve for excess water, and a durable brass spigot. At $79.00 with a 4.2‑star rating from 3,634 reviews, it balances cost and durability for garden irrigation and emergency use after appropriate treatment. For modular indoor storage, the Reliance Aqua Tainer 7‑Gallon 4‑Pack provides a total of 28 gallons of [rigid](#), stackable containers. Each unit includes a hideaway spigot and a vent that prevents vacuum lock. Priced at $103.40 for the pack and rated 4.5 stars from 250 reviews, it is suitable for families that need quick access to water in limited spaces. When the household requires the largest possible volume, the HOANK 55‑Gallon Water Barrel delivers industrial‑grade capacity, BPA‑free construction, and dual fittings for pump compatibility. At $114.99 and a 4.7‑star rating from 129 reviews, it offers a robust solution for long‑term storage in basements or garages. ## Step 4: Install and Secure the Container Installation varies by container type. For the waterBOB, lay the liner flat inside the bathtub, ensuring the fill sock aligns with the faucet. Connect the fill hose, fill the tub slowly to avoid air pockets, and then seal the inlet. The included siphon pump should be positioned near the outlet valve for convenient water retrieval. When setting up the RTS Rain Barrel, position the barrel on a level base or concrete blocks to prevent tipping. Attach the downspout to the inlet using a hose adapter, and secure the overflow valve to a drainage area away from the foundation. The flat‑back design allows the barrel to sit flush against a wall, conserving yard space. For the Aqua Tainer jugs, place each container on a sturdy shelf, ensuring the vent is open during filling to allow air displacement. After filling, close the vent and store the jugs upright to minimize movement. The HOANK 55‑Gallon Barrel requires a stable platform and may benefit from the optional pump accessory for efficient water extraction. Tighten both the NPT and buttress fittings with the supplied wrench to prevent leaks. Once sealed, label the barrel with the fill date and recommended chlorine dosage. ## Step 5: Fill, Treat, and Maintain the Water Supply After installation, fill the containers with potable water. If using tap water, add a chlorine concentration of one part household bleach (5‑6% sodium hypochlorite) per 1,000 gallons of water to achieve a residual of 0.5 ppm, which inhibits bacterial growth. For the waterBOB, a single 1‑liter bottle of bleach added to a full 100‑gallon load is sufficient. Stir the water gently with a clean utensil and allow it to sit for thirty minutes before sealing the container. Store the water in a cool, dark location to prolong freshness. Rotate the supply every six months by draining, cleaning, and refilling, or by adding fresh water to maintain a consistent chlorine level. Periodically inspect all seals, pumps, and fittings for signs of wear. Replace any cracked liners or deteriorating hoses immediately to avoid contamination. For rain‑water harvested in the RTS barrel, filter the water through a 0.2‑micron filter before chlorination, as natural debris may contain spores that chlorine alone cannot neutralize. ## Tips & Pro Tips - Label each container with the fill date and chlorine dosage; this practice prevents accidental consumption of stale water. - Store a small supply of powdered calcium hypochlorite as a backup disinfectant if liquid bleach is unavailable during an extended emergency. - Use a dedicated, food‑grade siphon pump—such as the one included with waterBOB—to avoid cross‑contamination when transferring water to smaller jugs. - When placing barrels on a concrete slab, elevate them slightly with cinder blocks to facilitate drainage and reduce ground moisture contact. - Consider adding a temperature‑controlled insulated cover for the HOANK barrel if it will be stored in a garage that experiences extreme temperature fluctuations. ## Troubleshooting ProblemPossible CauseSolution Water develops a foul odorInsufficient chlorine residualAdd additional bleach at a ratio of 1 ml per 10 gallons and stir.
