Water Crisis / Drought
The resource you can't survive 3 days without
Probability: HighSeverity: SevereGradual (months to years) or sudden (water main failure, contamination)Updated April 18, 2026
Overview
Water crises can be sudden (Flint, Michigan contamination; hurricane damage to water infrastructure; pipeline failure) or gradual (regional drought, aquifer depletion, population growth outpacing supply). The rule of 3 is unforgiving: 3 days without water means death. Beyond drinking, water is critical for sanitation, cooking, and hygiene. Municipal water supplies depend on electricity — a grid-down scenario automatically creates a water crisis. Water security is the single most important preparation after immediate safety.
Warning Signs
Drought declarations, utility notices about water restrictions, discolored or odd-smelling tap water, news of infrastructure damage in your water system.
Immediate Actions (First 24 Hours)
- Fill all available containers with tap water immediately
- Fill bathtubs using a WaterBOB or liners
- Do not flush toilets unnecessarily — conserve stored water
- Locate and identify all local water sources: streams, rivers, ponds
- Break out your water filter and purification supplies
- Begin immediate strict water rationing: 1 gallon per person per day minimum
Short-Term Preparation
- Store minimum 1 gallon per person per day for 30 days
- Acquire a quality water filter: Sawyer Squeeze, Berkey, or Katadyn
- Stock water purification tablets and unscented bleach for emergency purification
- Purchase WaterBOB bathtub liners (100-gallon emergency storage)
- Map all local water sources within walking distance
- Learn proper water purification for different contaminant types
Long-Term Preparation
- Install large-capacity water storage: 250–500 gallon tanks
- Install a rainwater collection system
- Dig or develop access to a private well
- Install a whole-house water filtration system
- Develop grey water recycling for irrigation
- Plant drought-resistant garden varieties
Essential Gear
- ▸55-gallon water storage drums (minimum 2–4)
- ▸High-capacity water filter (Berkey Big Berkey recommended)
- ▸WaterBOB emergency bathtub storage bladder
- ▸Water purification tablets (iodine and chlorine)
- ▸Manual water pump for well access
- ▸Rain barrels and collection system
- ▸Pool shock (calcium hypochlorite) for large-scale purification
Key Skills
- ▸Water purification: boiling, filtration, chemical treatment, UV
- ▸Finding water sources in various environments
- ▸Testing water quality
- ▸Water rationing and conservation
- ▸Rainwater harvesting and storage
- ▸Well maintenance and hand pump operation
Common Mistakes to Avoid
- Storing water in unsafe containers (milk jugs degrade, releasing chemicals)
- Not rotating stored water (replace every 6–12 months)
- Assuming your filter removes all contaminants — know what your filter does and doesn't remove
- Not considering sanitation water needs — beyond drinking, toilets/hygiene require significant water
- Waiting until a crisis to source a quality water filter
