I created a rain barrel water collection system using 4 rain barrels connected in series by their bottoms. The Quad rain barrel system stores roughly 220 gallons of rain water but fills as one complete unit. Excess water from the full barrels is routed to my compost pile for an extra soaking. Collection system utilizes 80 feet of PVC pipe that routes all rain water from north side of my house and garage to the rain barrels.
