Tier 02 · Sustain
Regional disasters, extended grid failures, and severe weather events routinely last 5–14 days. This tier extends what you've already built, without buying anything you won't actually use.
Why two weeks
The 72-hour standard was never meant to be the ceiling. These events crossed it.
The grid failure lasted 4 days at its peak. Many households went without power, heat, and running water for 5–10 days. Millions had no bottled water available within driving distance.
Full power restoration took 11 months for most of the island. For individual households, the practical question was: what do you do when organized aid is 5–14 days out?
55 million people lost power. Most service was restored in 2–4 days, but some areas went 5–7. Water systems in several cities failed because pumping stations lost power.
Grocery shortages, medication delays, and empty shelves weren't a power outage. They were a reminder that supply chains are thinner than most households assume. Two weeks of staples absorbed the disruption.
Two weeks is the standard used by the Red Cross, FEMA, and most state emergency management agencies for households in high-risk zones. It's also the point at which most regional supply chains and utility restoration crews complete their work. Beyond that, you're into the long-term tier.
Water
A two-week supply for a family of four is 56 gallons minimum. Most households can't store that in bottles. The solution is a hybrid approach: stored supply plus filtration capacity.
Stored supply
5–7 gallons per person is a realistic stored target for most households. Use food-grade water storage containers ($15–$35 for 5-gallon) rather than repurposed containers. Store away from direct sunlight and heat sources.
$30–$70 for a family of fourFiltration
A gravity-fed ceramic filter (like a Berkey or similar) processes tap water, bathtub water, or collected rainwater into drinking water without electricity. Rated for 3,000+ gallons. This is the most practical extension of any two-week plan.
$200–$400 one-timeHidden reserve
The water in a standard tank water heater is drinkable in most emergencies. To access it: turn off the power or gas, attach a hose to the drain valve at the base, and drain into clean containers. Let sediment settle before drinking.
Already there — no costFill the bathtub before the storm arrives. A standard bathtub holds 40–60 gallons. A WaterBOB liner ($25–$35) keeps it clean and usable for up to 4 weeks. It takes 20 minutes to fill and is the easiest two-week water extension available.
Food
The two-week food tier isn't a pile of emergency rations. It's a pantry of staples you rotate through regularly — bought at normal prices, eaten before they expire.
The core pantry — 14 days for one adult
Total cost for one adult: approximately $60–$90. Multiply by household size.
A single-burner propane camp stove ($30–$60) covers nearly everything. Use it outdoors only, or in a well-ventilated garage with the door open. Keep 8–10 standard 1-lb canisters on hand (about $2.50 each) for two weeks of cooking.
Canned goods are already cooked and require no heat. Eating them cold extends your fuel supply significantly for a two-week stretch.
A full freezer maintains safe temperature for 48 hours without power. A half-full freezer: 24 hours. A refrigerator: 4 hours. Order of operations:
Medical
Medications run out. Pharmacies close. Supply chains disrupt. A two-week buffer on critical medications is the most overlooked piece of the two-week tier.
Most insurers allow a 90-day fill for maintenance medications. Request it at every refill. If you're on a 30-day schedule and refill 5 days before you run out, over three months you build a 15-day buffer automatically.
Insulin, some eye drops, and other biologics require refrigeration. A small medical cooler with ice packs buys 24–48 hours. A portable power station keeps a mini-fridge running for several days. See the medical devices power guide for specifics.
Over-the-counter supplies to stock for two weeks: pain relievers (acetaminophen and ibuprofen), antihistamine, antidiarrheal, antacid, electrolyte powder, and wound care supplies beyond what's in the 72-hour kit. Total cost: $60–$80.
Chronic condition planning
If anyone in your household manages a chronic condition, the two-week tier requires specific planning beyond medication supply. Consider:
Sanitation
Water and food get most of the attention. Sanitation is what most two-week plans skip entirely, and it's the category that turns a manageable disruption into a health emergency.
If the municipal sewer system fails or your septic system is compromised, using the toilet can cause backflow into the house. Stop using it. A 5-gallon bucket with a snap-on toilet seat ($20–$40) and heavy-duty waste bags is the solution.
Double-bag waste. Seal tightly. Keep near an exterior door. Your county's emergency management agency will publish disposal guidance during an event.
Waterborne illness is the main sanitation risk after infrastructure disruption. Keep hand sanitizer (at least 60% alcohol) at every sanitation station. Wet wipes are not a substitute for handwashing but work for quick cleaning between washes.
A gravity hand-wash station — a 5-gallon jug with a spigot over a basin — uses minimal water and creates the habit.
Two-week sanitation supplies for a family of four:
Shelter comfort
You don't need to heat or cool the whole house. You need one room that's livable. That's a much more achievable target.
Identify the smallest interior room (fewest exterior walls, lowest ceiling). Hang blankets over doorways and windows to retain heat. A sleeping bag rated to 0°F keeps a person warm with no supplemental heat source. Two people sharing a small space with good sleeping bags need very little additional heating.
For supplemental heat: a propane heater designed for indoor use (Mr. Heater Buddy type, $80–$120) with a window cracked 1 inch for ventilation. Never use an outdoor propane heater indoors. Never use a gas oven to heat a space.
Heat is the more dangerous failure mode. Identify the coolest room in the house (typically the lowest floor, north-facing, smallest windows). Close blinds and curtains to block radiant heat from sunlight. Cross-ventilate with open windows after sundown when outside air cools below inside air.
A battery-powered or USB fan ($20–$50) moves air significantly. A misting bottle with a fan creates an evaporative cooling effect. Wet towels on the back of the neck and wrists cool core temperature faster than anything else.
During wildfire smoke events or nearby chemical incidents, the goal is to reduce indoor air infiltration. Close all windows and doors. Turn off HVAC systems that draw outside air. Seal gaps around doors and windows with wet towels or tape if the event is severe.
An air purifier with a HEPA filter ($80–$200) reduces particulate matter significantly for smoke events. N95 masks worn indoors during peak smoke hours also help. Monitor AQI through your local NWS forecast office or AirNow.gov.
Power and comms
Most households need far less than they think. A two-week power plan is not a whole-house generator. It's a prioritized stack that covers the most critical needs first.
10,000–20,000 mAh. Charges most smartphones 3–5 times. The minimum viable power backup. Get two, keep both charged. Covers phones, earbuds, small lights.
500–1,000 Wh. Runs a CPAP for 2–4 nights, charges phones repeatedly, powers a small fan or lamp. Pair with a 100W foldable solar panel ($80–$150) to recharge during daylight. The most practical two-week power solution for most households.
Required for running a refrigerator, a window AC unit, or well pump. Outdoor use only — carbon monoxide from generators kills people every major outage. Requires fuel storage (treated gasoline in approved containers, rotated every 6–12 months). Read the generator guide before buying.
Communication beyond cell phones
A pair of FRS/GMRS handheld radios ($30–$80 for a pair) works when cell networks are overloaded or down. Range is 1–5 miles in open terrain, less in urban areas. No license needed for FRS. GMRS (higher power) requires an inexpensive FCC license. See the FRS/GMRS guide.
You already have one from the 72-hour kit. In the two-week tier, it becomes your primary news source for outage updates, boil-water advisories, and reopened roads. Keep batteries fresh. The hand-crank feature is a backup, not a primary — hand-cranking for 5 minutes gives 30–60 minutes of listening.
Cash and access
Card readers, ATMs, and mobile payment systems all require power and network connectivity. In a regional outage, cash is the only reliable payment method for the first several days.
Fives, tens, and twenties. Vendors who have cash often can't make change for large bills during a disruption. Keep this separate from your wallet, in the go-bag or a fixed home location.
The Texas winter storm of 2021 produced gas lines 5–8 hours long. The people who topped off their tanks before the storm hit had options. Those who didn't were effectively stranded. Above-half is the habit. Full before any named storm.
Some banks allow limited cash advances to stranded customers at branches even without ID. Your bank's customer service number belongs on the written contact card from the 72-hour plan.
The full two-week cost estimate
For a household of four, starting from a complete 72-hour kit:
Built over time, this is $80–$150/month for a year. You already have the 72-hour kit. The water filter and power station are the two largest single purchases.
The discipline
The most common two-week kit failure is not a gap in supplies. It's supplies that expired three years ago and were never replaced. Rotation discipline solves this permanently.
When you buy a new can of beans, it goes to the back of the shelf. The oldest can comes to the front for regular cooking. After three months of this habit, your pantry is always stocked with the freshest versions of everything you store.
Set one calendar reminder per year. Open every storage container. Check expiration dates. Test flashlights and replace batteries. Taste-test the water. Confirm all medications are current. The whole review takes 45 minutes.
Write the purchase date on the top of every container with a marker. You don't have to remember when you bought it — you can see it. This alone prevents most rotation failures.
Shelf life quick reference
Dates refer to quality, not safety in most cases. A can of beans from 2020 is likely still safe but may have degraded in texture and nutrition. When in doubt, smell and examine before eating.
The next step
Long-term resilience isn't more gear. It's the skills, documents, relationships, and financial decisions that determine how fast a household recovers from anything.
