Rotation Schedule Tips:
Small Families (1-3 people):
5-gallon containers offer the best balance of portability and efficiency. Easy to handle at 42 lbs when full.
Large Families (4+ people):
Mix of 5-gallon and larger containers (15-30 gallon) for efficiency while maintaining some portability.
Long-term Storage:
55-gallon drums with pumps offer maximum efficiency for permanent installations.
Apartment Living:
Water bricks or 3-gallon containers maximize space efficiency in limited storage areas.
Dogs: Approximately 1 ounce per pound of body weight daily (a 50-lb dog needs about 3 cups or 0.75 gallons)
Cats: About 3.5-4.5 ounces per 5 pounds of body weight daily (a 10-lb cat needs about 0.2 gallons)
Small pets: Rabbits, birds, and small mammals need proportionally less but should not be forgotten
⚠️ Important Pet Considerations:
🚫 Warning Signs:
✅ Prevention Tips:
Hurricanes, earthquakes, tornadoes can disrupt water supplies for weeks. 14+ day supply recommended.
Extended outages affect pumps and treatment facilities. 3-7 day supply usually sufficient.
Infrastructure failures can leave neighborhoods without water for days. 3-5 day supply recommended.
Chemical spills or biological contamination require extended water storage. 7-14 day supply needed.
✅ Available when needed, reliable quality, one-time container investment
❌ May be unavailable, price gouging, quality concerns, transportation issues
For a 4-person household with a 7-day supply, pre-planning saves you $200-400+ compared to emergency purchasing, while guaranteeing availability when you need it most.
