Emergency Water Preparedness Guide

A practical starting point for storing safe water and deciding what to do when normal service is interrupted.

Water planning starts with a realistic quantity, a safe source, clean containers, and a treatment plan matched to the actual hazard. Filtration, purification, and disinfection do different jobs; none is a universal fix for chemical contamination.

Start here: CDC’s baseline is at least 1 gallon per person per day for 3 days and a goal of 2 weeks if possible. Store more for pets, hot weather, illness, pregnancy, or household needs. Use clean food-grade containers and rotate self-filled water every six months.

1 gallon per person per day is an acceptable emergency-water baseline. CDC recommends at least three days for drinking, cooking, brushing teeth and other uses, and encourages a two-week supply when possible. This is a useful, legitimate level of preparedness.

About 3 gallons per person per day is an optional Prepared Home Solutions stretch goal when space, weight, budget, structural/storage capacity, and household circumstances allow. It is not a CDC/FEMA minimum. It offers extra flexibility for drinking, cooking, basic hygiene, cleaning/sanitation and unexpected needs. Build in stages: acceptable emergency baseline → improved reserve → optional PHS stretch goal. Add for pets and household-specific needs.

Protect

Clean containers, label dates, and know whether your source needs treatment.

A layered household water plan

Stored potable water is the immediate foundation, but it is not the complete long-duration plan.

  1. Store: keep safe water ready to use.
  2. Source / collect: identify where additional water could come from and how to collect it.
  3. Transport: plan manageable containers and a way to move them.
  4. Filter / purify / disinfect as appropriate: match verified equipment and instructions to the actual contamination risk.
  5. Boil when appropriate: plan the heat source, fuel, vessel and safe operating location.
  6. Handle and store safely: protect treated water in clean, covered containers.

This is a planning framework, not a requirement to apply every treatment step to every source. Ordinary household filtering, boiling or disinfection must not be assumed to make water containing fuel, toxic chemicals, radioactive material or similar hazardous contamination safe. Use another safe source and follow official instructions.

Put your water plan on paper

Use the completed PHS Household Emergency Water Plan & Worksheet (PDF) to record your stored supply, source backups, equipment and next steps. Learn through the guides, answer specific questions, plan with the worksheet, then act on the gaps that matter to your household.

If normal tap water fails

If my normal tap water is unavailable or unsafe, where will my next water come from? Municipal service can be disrupted by power outages, main breaks, loss of pressure, treatment-system problems, flooding, contamination or infrastructure damage. A private well may still contain groundwater while its electric pump cannot run.

A boil-water advisory, do-not-drink advisory and do-not-use advisory are different. A do-not-use notice can prohibit all contact; do not substitute boiling for the stated restriction. See CDC’s drinking-water advisory guidance.

Safety first

Boiling and chemical disinfection address many germs, not chemical contaminants. Follow local water advisories. If authorities warn of chemical contamination or issue a do-not-use notice, do not assume household treatment makes the water safe.
