How much water you actually need

Emergency planners use a simple baseline: 1 gallon per person per day for drinking and basic hygiene. Plan for 3 days minimum. A two week target is better for earthquakes, power outages, or supply disruptions.

Quick planning table

Example: A family of 3 planning for 14 days needs 42 gallons. With 3 gallon glass bottles that is 14 bottles. Add 1 to 2 extra bottles if you live in a hot climate or have infants or elderly family members.

Shelf life and rotation schedules

Distilled water is simply H₂O with no dissolved minerals and no additives. In a clean, sealed glass bottle stored in a cool, dark place, it remains stable for a long time because there is very little for microbes to feed on and glass is non porous and non reactive.

• Storage goal: Cool, dark, dry, off the floor, away from sunlight and chemicals.
• Do not open until needed. Once opened, use within 3 to 7 days and keep the cap on between uses.
• Visual and smell check: If it looks cloudy, has growth, or smells off, discard and sanitize the container.

Rotation plans that are easy to follow

Pick a rotation cadence that fits your habits. Mark each bottle with the delivery or fill date.

Container prep and sanitation

Glass is ideal for storage because it does not leach, hold odors, or deform over time. Before first use and during annual rotation, sanitize containers, caps, and any funnels.

1. Wash bottles and caps with hot water and fragrance free soap. Rinse well.
2. Sanitize with a food safe solution:
   • Option 1: Unscented household bleach at 1 teaspoon per quart of water. Contact time 2 minutes. Drain and air dry. Do not sniff.
   • Option 2: 70 percent isopropyl alcohol. Swirl to coat, drain, and air dry.
3. Do not towel dry. Air drying limits re contamination.
4. Fill with fresh distilled water and cap tightly.
5. Label the cap with date and set name if you use a rotation system.

Boil vs distill decision tree

Use this quick path when supply lines are disrupted.

1. Do you have sealed distilled water on hand
   • Yes: Use it for drinking, baby formula, CPAP, and cooking that does not get re boiled.
   • No: Go to step 2.
2. Is the tap water clear and not chemically contaminated
   • If contamination is unknown or chemical odors are present: Do not drink or boil. Use only sealed water. Contact local authorities.
   • If contamination is microbial only or unknown but no chemical smell: Bring to a rolling boil for 1 minute. Cool and store in clean containers. Use within 24 to 48 hours.
3. Do you need ultra low mineral water for devices or medical use
   • Yes: Use distilled water. Boiling does not remove minerals. Minerals can foul humidifiers, irons, and CPAP machines.
   • No: Boiled water is acceptable for general drinking and cooking if the only risk is microbes.

Smart placement and safety

• Store bottles low and secured to prevent falls during earthquakes.
• Keep away from garage chemicals, gasoline, and paint to avoid vapor transfer to caps.
• Use a first in first out shelf layout. Oldest bottles in front.
• Place a small battery lantern near your storage area for easy access at night.

Fast answers

How long does distilled water last In clean, sealed glass kept cool and dark, it remains stable for extended periods. Use a rotation plan so you always have fresh stock.

Do minerals matter For emergencies, the priority is safe water. Many households prefer distilled daily for taste, appliance protection, and consistency. Minerals should come from food, not scale in your kettle.

Why glass Glass is inert, reusable, and easy to sanitize. It avoids microplastic concerns and does not deform in heat.
