Water, power and food security

Going beyond the standard two-week reserve

Core Household Reserves covers the standard baseline; this page addresses what changes if a disruption extends well beyond that window — a genuinely low-probability Tier 3 scenario, but one worth understanding rather than assuming the standard checklist simply scales linearly.

Water beyond two weeks

Storage alone becomes impractical past a certain point; understanding your local water sources, basic water-treatment methods (filtration, purification tablets, boiling), and whether your area has accessible groundwater or surface water becomes more relevant than further storage.

Power beyond a short outage

A generator sized for a multi-day outage is a very different proposition from sustained power over weeks — fuel storage, resupply, and maintenance become the binding constraint rather than the generator itself. Households in this planning tier often shift emphasis toward reducing essential power draw (efficient appliances, manual alternatives) rather than purely scaling up generation.

Food beyond a month

Extended food security shifts from “stockpile” thinking toward a combination of a larger rotated reserve, basic food-preservation skills (canning, dehydrating), and, where feasible, small-scale food production — none of which need to be adopted at survivalist scale to meaningfully improve resilience.

The community multiplier

As with every Tier 3 topic in this manual, a functioning local network (see community and local networks) extends every one of these individual measures further than any single household can manage alone — shared resources, shared knowledge, and shared labor scale in ways individual stockpiles cannot.
