Know
Use at least one gallon per person per day as a starting point for drinking, food preparation, and limited hygiene. Add water for pets, hot weather, and other household needs. A filter does not remove every contaminant. Boiling or disinfecting cannot make chemically contaminated water safe.
Get
Choose a manageable mix of bottled water and refillable containers. Include a way to dispense the water. Use your actual stored amount and selected purchases to check the remaining gap.

Your containers and stored water
Record actual safe water held, not just capacity. Pools, a future bathtub fill, or a water-heater tank are not counted as stored drinking water.

Receiving an empty container adds capacity and a filling task, not available water.
Why, limitations, and setup
Reusable water storage with a dispensing spigot. Choose a container you can handle when full.
Exact variant: 7-gallon container, not the 4-gallon version. Spigot included.
Quantity rule: Uses only its allocated storage-capacity gap, divided by 7 and rounded up. An empty purchase adds capacity and a filling task, not available water.
Limitation: Store as directed, away from heat and sunlight. Stack only when empty. A filled container is heavy; choose smaller equivalents if needed.

Do
Count the safe water you already have. Choose food-grade containers that fit your storage space and are manageable when full. Clean and fill them using official instructions. Label the storage date, plan rotation, and test the spigot or pump. Keep drinking water separate from water reserved for other uses. Count only water actually available.
Plan progress records tasks you have completed. It is not a prediction of safety or a guarantee of self-sufficiency.
Extended
A 90-day target requires substantial storage. Review space, handling, and a verified replenishment plan. Do not count an unknown future water source as stored supply.
