Why This Skill Matters in an Emergency or Survival Situation

Collecting rainwater is a crucial survival skill as it provides a reliable source of water during emergencies or survival situations. In areas prone to droughts or where water supplies might be compromised, having a rainwater collection system ensures you have a steady supply of water for drinking, cooking, and sanitation.

What You Need

Materials

  • Rain barrel or large plastic container (at least 55 gallons)
  • Screen or mesh cover for the top of the barrel
  • PVC pipe or spigot for water collection
  • Hose or pipe for directing water into the barrel
  • First flush diverter (optional but recommended)
  • Filter (optional but recommended)
  • Storage containers for clean water

Tools

  • Drill
  • Screwdriver
  • Pliers
  • Measuring tape
  • Level
  • Silicone sealant or caulk

Knowledge

Understanding basic plumbing principles and safety measures for handling water.

Step-by-Step Instructions

  1. Choose a Location: Place the barrel near a downspout or under a roof edge where water naturally flows. Ensure the location is level and has enough space for the barrel.
  2. Prepare the Barrel: Clean the barrel thoroughly. Remove any labels or residue. If using a new barrel, check for any manufacturing defects.
  3. Install the Screen: Cut a piece of screen or mesh to fit the top of the barrel. Attach it securely to prevent debris from entering the barrel.
  4. Connect the Downspout: Use a diverter to redirect water from the downspout into the barrel. Ensure the connection is watertight to prevent leaks.
  5. Add a First Flush Diverter: This device flushes out the first few gallons of water after a rainstorm, which typically contain the most debris.
  6. Install the Spigot: Drill a hole near the bottom of the barrel and install a spigot. This allows you to easily access the water without contamination.
  7. Add a Filter: If necessary, install a filter at the spigot to remove any remaining particles or contaminants.
  8. Secure the Barrel: Ensure the barrel is stable and won’t tip over, especially if it’s full of water.
  9. Direct Water to Storage: Connect a hose or pipe from the spigot to a storage container. This allows you to easily transfer water to a more convenient location.
  10. Monitor and Maintain: Regularly check the system for leaks or blockages. Clean the screen and filter as needed.

Common Mistakes and How to Avoid Them

  • Not Securing the Barrel: Ensure the barrel is stable and won’t tip over. Use straps or stakes to secure it.
  • Ignoring Debris: Use a screen and first flush diverter to prevent debris from entering the barrel.
  • Neglecting Maintenance: Regularly check the system for leaks and clean the screen and filter.
  • Incorrect Placement: Place the barrel near a downspout or under a roof edge to maximize water collection.

Variations, Tips, and Related Techniques

  • Multiple Barrels: Connect multiple barrels to increase water storage capacity.
  • Solar Heating: Use black barrels to heat water naturally using the sun’s energy.
  • Purification Methods: Consider boiling water or using a water filter for safe drinking water.
  • Legal Considerations: Check local regulations regarding rainwater collection before setting up your system.

TLDR

Collect rainwater using a barrel near a downspout, with a screen and first flush diverter to prevent contamination. Secure the barrel, maintain it regularly, and consider multiple barrels for increased capacity. Legal compliance is essential.
