Rainwater Collection & Storage

Simple Setup with Tarps 

1. Tarp Funnel Method

  • Spread a clean tarp slightly angled toward a collection point.
  • Runoff channels into a container (trash bin, barrel, or buried cistern).

2. Buried Container Reservoir

  • Dig a hole for a food-grade barrel or IBC tote.
  • Cover with a lid to prevent contamination and evaporation.
  • Funnel water via tarp, gutter, or PVC pipe.

3. Storage Tips

  • Use food-grade containers only.
  • Keep containers covered and shaded to prevent algae growth.
  • Add 1 tsp of unscented bleach per 5 gallons if long-term storage is needed.
  • Rotate every 6–12 months.

 

Low-Cost Urban Hacks

  • Buckets & Barrels: Restaurants/bakeries often give away food-grade buckets free.
  • DIY Grow Bags: Use old rice sacks, feed bags, or reusable shopping bags.
  • Vertical Gardening: Pallets or shelves maximize tiny balconies.
  • Rainwater Pre-Filter: Stretch a T-shirt or screen over the barrel opening to keep out debris.
