STEP-BY-STEP
Install the Water Diversion System
Connect a T-shaped pipe to your gutter downspout. This connector will redirect rainwater into your storage system
This connection was designed so that when the barrels are empty, water flows directly into the storage system. Once the barrels are full, the water automatically continues its normal path through the pipe, preventing overflow and ensuring a continuous flow.
Build the Barrel Tower
Stack three plastic barrels vertically using a strong support structure. Place the system at a higher level than where the water will be used so gravity can create natural pressure.
Connect the Barrels
Use PVC pipes and elbow joints to connect the barrels from top to bottom. This allows water to fill evenly across all levels.
Install the Water Outlet
Install a faucet (tap) at the bottom barrel. This will allow you to easily control and access the stored water for irrigation, cleaning, or other uses.
Seal All Connections
Make sure all joints are properly sealed to avoid leaks and ensure system efficiency.
Final Result
You now have a simple and effective rainwater collection system that stores water efficiently, prevents overflow, and uses gravity to provide natural pressure.
