How to Filter and Store Water for Emergencies

Water is one of the most important things in any emergency situation, as we, being Krav Maga studio owners and family resilience experts, understands. Between life and death lies ensuring a secure and reliable water supply. In this blog post I will take you through the steps of filtering and storing water so you can get ready for emergencies.

Understanding the Importance of Water Storage

Water is necessary for drinking, cooking, and sanitation. In an emergency it may not be possible to have access to clean water thus there is need of having a stored supply.

Daily Water Needs

• Individual Requirement: Each person needs about a gallon of water per day for drinking or basic sanitation during emergencies.
• Family Calculation: The number of family members multiplied by the daily requirement should give you enough water for as many days as you want to prepare (e.g., a family of four for seven days needs 28 gallons).

Choosing the Right Containers for Water Storage

Types of Containers

• Plastic Bottles: Use food-grade plastic containers that have not contained any harmful substances.
• Glass Bottles: Suitable for water storage but are fragile and can break easily.
• Stainless Steel: Durable and safe for storing water, but ensure they are food-grade and not previously used for other liquids.

Container Preparation

• Cleaning: Rinse containers with soap and hot water. Use 1 tsp household bleach per quart rinse well with clear running tapwater.
• Sealing: Ensure containers have tight-fitting lids to prevent contamination.

Filtering Water Before Storage

Water Sources

• Tap Water: Typically safe for storage without additional treatment if it comes from a municipal supply.
• Natural Sources: Water from rivers, lakes, or rainwater needs to be filtered and treated before storage.

Filtration Methods

• Commercial Water Filters: Use filters designed to remove bacteria, protozoa, and other contaminants.
• DIY Filters: Create a simple filtration system using materials like sand, gravel, and activated charcoal. However, this should be a last resort as it might not be as effective as commercial filters.

Boiling and Chemical Treatment

• Boiling: Boil water for at least one minute to kill pathogens. Let it cool before storage.
• Chemical Treatment: Use water purification tablets or household bleach (5-8 drops per gallon) to disinfect water. Stir well and let it sit for 30 minutes before use.

Storing Water Safely

Storage Location

• Cool, Dark Place: Store water in a cool, dark place away from direct sunlight and chemicals.
• Avoid Extreme Temperatures: Do not store water in areas where it can freeze or become too hot, as this can compromise the container and water quality.

Regular Maintenance

• Rotation: Rotate stored water every six months to ensure freshness. Label containers with the date of storage.
• Inspection: Regularly check containers for leaks, cracks, or signs of contamination.

Emergency Water Sources and Treatment

Alternative Sources

• Rainwater: Collect using clean containers or tarps. Always filter and treat before drinking.
• Natural Bodies of Water: Rivers, lakes, and streams can be used, but require thorough filtration and disinfection.

Portable Water Filters

• Survival Straws: Compact and easy to carry, these filters allow you to drink directly from natural water sources.
• Portable Pumps: Handheld devices that filter water and are ideal for larger volumes.

Emergency Water Purification Techniques

Solar Disinfection (SODIS)

• Method: Fill clear plastic bottles with water and place them in direct sunlight for at least six hours. UV rays from the sun can kill harmful pathogens.
• Effectiveness: Works best with clear, low-turbidity water and in sunny climates.

Improvised Filtration

• Materials: Use items like coffee filters, cloth, or bandanas to remove large particles.
• Process: Combine improvised filtration with boiling or chemical treatment for better safety.

Summary

Part of emergency readiness involves being prepared with reliable water supplies. You can secure your family’s safety and resilience by learning how to filter, store and purify water in any crisis situation. Keep in mind that proactive preparation is the core principle behind efficient emergency management.
