Step-by-Step Instructions

01
Know your target: 1 gallon per person per day
14 gallons covers 1 person for 2 weeks — the realistic target for an apartment. For 2 people, aim for 21–28 gallons. Most disasters resolve within 2 weeks; this window is your goal, not a year-long cache.

02
Choose your storage method
Three options for apartments: (1) Reused 2-liter soda bottles — free, store under beds or in closets, rotate every 6 months. (2) WaterBricks — stackable, food-grade, 3.5 gallons each, fit in a corner closet. (3) WaterBOB bathtub bladder — 100+ gallons deployed in 45 minutes before a storm, takes zero storage space when empty.
Warning: Do NOT reuse bottles that held milk, juice concentrate, or anything other than water or soda. Milk proteins harbor bacteria even after washing. -
03
Fill and seal containers
Fill with tap water — chlorinated municipal water stays safe for 6–12 months in sealed food-grade containers. For WaterBricks: fill with a funnel, screw cap tightly. For reused bottles: wash 3× with hot soapy water, rinse thoroughly, fill to the top (minimal air gap), cap tightly. Label each with the fill date using a marker.

04
Choose your storage location
Best apartment spots: bathroom closet (climate-controlled, accessible), under bed (invisible, cool), laundry closet (cool, dark, low-traffic). Worst spots: near radiators, ovens, or water heaters. Never store higher than waist height — heavy containers fall and burst. Keep away from direct sunlight.

05
Set up your purification backup
Even stored water benefits from a backup filter in case of contamination. A LifeStraw ($25) filters 1,000 liters and requires no batteries or pumping — just drink through it. Bleach tablets (2 drops per liter, wait 30 minutes) kill bacteria and viruses at almost zero cost. Both fit in a drawer.

06
Build your rotation routine
Every 6 months: use the oldest water for plants or cleaning, refill with fresh tap water. Set a phone reminder. For WaterBricks, once per year is sufficient (they're rated for 5-year storage). For reused plastic bottles, rotate more frequently — they degrade faster than food-grade containers.
Pro Tips
- WaterBricks stack perfectly and are rated for 5-year storage — set-and-forget for apartment dwellers.
- The WaterBOB is your secret weapon if you have 48-hour storm warning. 100 gallons for $30 beats any other method per dollar.
- Tap water is already treated with chlorine — you don't need to add anything. Just seal it tightly and date it.
- Never store water in old milk jugs — the protein residue feeds bacteria even after thorough washing.
- 4 WaterBricks (14 gallons) fit in a 2×2 ft closet corner and weigh about 117 lbs when full — test your floor weight before stacking 5+ high.
