19 Rainwater Collecting Ideas That Are Functional, Beautiful, and Easy to Build

Materials Needed:
- 1 IBC tote (275–330 gallons)
- Corrugated metal roof panel (5’–6′ long)
- 4 support posts (4″x4″)
- PVC pipe or flexible downspout
- Screws, bolts, brackets
- Optional: debris screen, overflow hose
Step-by-step Guide:
Step 1: Build a basic roof structure over the IBC tank using posts and a sloped corrugated metal sheet. Ensure the slope directs water to one side.
Step 2: Connect a PVC pipe or downspout to the roof’s low end and route it into the IBC tank’s top inlet. Seal the joint to prevent splashing or leakage.
Step 3: Place the tote on blocks or pavers for stability and easier access to the bottom spout.
Step 4 (Optional): Add an overflow pipe at the top or a mesh filter over the opening to keep out leaves and insects.
#19. Gravity-Fed Elevated IBC Water Tower
Built like a mini water tower, this DIY setup elevates an IBC tank for serious water pressure and storage.
Materials Needed:
- 1 IBC tote (275–330 gallons)
- 4–6 pressure-treated posts (4″x4″, 8 ft+)
- 8–10 wooden braces (2″x4″ or 2″x6″)
- Galvanized metal brackets and bolts
- Hose, spigot, or faucet kit
- Drill, saw, wrench
- Ladder or scaffolding
Step-by-step Guide:
Step 1: Build a tall support frame using the 4×4 posts as legs and diagonal cross-braces for strength. Use galvanized brackets and bolts to secure all joints.
Step 2: Create a level platform at the top using thick planks, wide enough to support the entire IBC tote base. Reinforce with extra braces underneath.
Step 3: Carefully lift and place the tote onto the platform (use a lift or multiple people for safety).
Step 4: Connect a hose or pipe to the bottom outlet. Install a spigot or nozzle as needed for controlled water flow. Secure the system against wind or tipping.
