Build Your Own 550-Gallon Rainwater System
Don't let FREE rainwater slip away from your home.
 
This guide shows you how to build a practical rainwater system using two IBC totes, common plumbing parts, and a simple layout. The goal is to help you store more water for your garden without guessing your way through the build.
 
What This Guide Helps You Do
Capture roof runoff from a downspout
Store up to 550 gallons of water
Use IBC totes as low-cost storage tanks
Add a first-flush diverter
Plan overflow before heavy rain
Build a cleaner exterior cover
Avoid the mistakes from my first design
 
Why I Made This Guide
My first rainwater system started as a basic backyard project. After sharing it on YouTube, I received years of questions about parts, setup, layout, overflow, pumps, filters, and design changes.
This updated guide pulls those lessons into one cleaner plan.
