Whether you're a homesteader, gardener, or just someone who loves a clever DIY, collecting rainwater is one of the simplest ways to save money, conserve resources, and add charm to your outdoor space.
In this list, you'll find 19 creative rainwater collecting ideas that don’t just work, they look great doing it.
From rustic barrels to sculptural downspouts and off-grid setups, each project proves that functionality and beauty can absolutely go hand in hand.
With a compact corrugated roof feeding into a primary red barrel and a secondary gray overflow barrel, you won’t lose water even during a heavy downpour.
Step 1: Build a simple frame using 4 wooden posts and cross beams to support the roof. Raise one side slightly for water flow. Secure a corrugated panel roof on top.
Step 2: Place the main rain barrel on a sturdy pallet or platform beneath the roof’s edge. Install a downspout or gutter to direct runoff into the top of this barrel.
Step 3: Drill an overflow hole near the top of the first barrel and connect a hose that leads to the second barrel. Use a clamp to hold it in place.
Step 4: Add a spigot to the lower section of each barrel for easy water access, then seal around all fittings to prevent leaks.
Sometimes the simplest ideas are the most efficient. This raised rain barrel setup uses a sturdy wooden stand to lift the barrel for better gravity-fed water pressure.
Step 1: Build a square stand with the four wooden posts as legs and 2x4 planks for bracing across the middle and bottom. Make sure it's level and sturdy.
Step 2: Place the barrel vertically onto the stand. Mark and drill a hole near the bottom for the spigot, then install and seal it tightly.
Step 3: Connect the gutter or downspout into the top of the barrel using a diverter or flexible pipe. Ensure it directs water cleanly into the barrel.
Step 4: Optionally, drill a small overflow hole near the top and connect a hose to redirect excess water away from your foundation.
This upcycled rain barrel bench is more than just a place to sit, it’s a smart, sustainable way to collect water while making the most of your greenhouse setup.
Step 1: Place the barrels on their sides where rain naturally flows off your greenhouse or shed. Use chalk or marker to outline a large U-shaped section across the top.
Step 2: Carefully cut along the outline using a jigsaw. Remove the section and sand the cut edges.
Step 3: Push the barrels snug against the structure to collect rain runoff. Use wood planks or brackets to secure them in place if needed.
Step 4: Add a drainage hole or faucet at one end if you want to redirect or store the collected water.
Perched on top of a red barrel, the wide plastic basin captures even light rainfall and channels it straight into the tank.
Step 1: Place the barrel on a sturdy base made from stacked concrete blocks. This gives height for hose pressure and spigot access.
Step 2: Drill a hole near the base and install a spigot, sealing tightly to prevent leaks. Attach a hose if needed for garden use.
Step 3: Cut or adjust the barrel lid to allow the funnel to rest securely on top. Make sure the center directs water into the barrel.
Step 4: Secure the funnel with ties or weight if in a windy area, and position the setup in an open spot with good sky exposure.
When serious water storage is your goal, an IBC (Intermediate Bulk Container) tote is the way to go. This setup features a massive 275-gallon tank encased in a custom wood frame for added strength and stability.
Step 1: Build a wooden frame around the IBC tote using 4"x4" posts for corners and 2"x4" planks for cross bracing. Use brackets and screws for reinforcement.
Step 2: Position the tote near a roof runoff point. Angle a PVC pipe or downspout from the roof into the tote’s top port to collect rainwater.
Step 3: Ensure the tank is level and stable. Use bricks or pavers underneath if needed.
Step 4: Connect a hose or spigot to the bottom valve for easy water access. Secure all joints and fittings to avoid leaks.
Wrapped in vertically mounted, charred wooden slats and accented with black metal bands, it gives the look of a classic wine cask while functioning as a discreet water storage system.

Step 2: Cut wood slats to match the height of the barrel. Optionally, char the wood using a torch for that beautiful scorched look.
Step 3: Screw or nail the slats vertically around the barrel, spacing them evenly. Wrap metal bands around the top and bottom for a polished finish.
Step 4: Ensure the spigot is still accessible, and test the system during a light rain to check flow.
When space is tight but your thirst for rainwater isn’t, this vertical barrel system is a game-changer. Water flows down from the roof through a gutter into the top barrel and connects through tubing into each one below.
Step 1: Build a tall rectangular frame using four vertical posts and cross-beams spaced to hold each barrel horizontally. Reinforce with metal brackets and bolts.
Step 2: Cut holes and install a spigot at the base of the bottom barrel and overflow/drain fittings on each of the others.
Step 3: Stack the barrels on the frame, securing each one between the beams. Connect them using tubing or hose so water flows from the top down.
Step 4: Position a gutter or downspout to feed directly into the top barrel’s inlet. Seal all fittings and connections for watertight flow.
Whether you’re collecting water for camping, permaculture, or backwoods emergencies, this setup shows how simplicity can be incredibly effective.
Step 1: Drive the wooden poles into the ground in a wide circular pattern, creating a teepee-like structure. Tie the tops together with rope.
Step 2: Attach the fabric inside the frame to form a wide funnel. Ensure it’s deep enough to guide water down to a central point.
Step 3: Tie the funnel’s bottom securely above the collection bucket. Make sure the water exits cleanly into the container without leaks.
Step 4: Place the bucket in the center under the funnel. Cover it with a loose lid or mesh to keep debris out while allowing water in.
Strategically placed among your plants, these decorative rain catchers collect small amounts of water for pollinators or birds and add a whimsical touch to any flower bed.
There’s something poetic about this setup. A delicate rain chain leads water from the roof to a beautifully glazed ceramic urn below, turning a simple function into a gentle visual feature.
Step 1: Remove the downspout at the corner of the roof and install a rain chain hanger or hook in its place. Make sure it’s securely anchored.
Step 2: Hang the rain chain so it gently touches or hovers slightly above the base of the container. Adjust the length if needed.
Step 3: Place the large ceramic pot directly beneath the chain. Level the bottom using gravel or bricks if the ground is uneven.
Step 4 (Optional): Add a screen or mesh insert inside the pot to catch leaves or debris while allowing rainwater to collect cleanly.
This sleek design disguises a bulky IBC tank with custom slatted wood cladding, turning an industrial solution into a backyard feature.
Step 1: Place the IBC tote on a level concrete or paver surface near your downspout. Ensure the bottom valve is accessible.
Step 2: Build a square wooden frame around the tank using corner posts. Leave top access for the inlet pipe and occasional maintenance.
Step 3: Attach slats horizontally around the frame with even spacing, allowing ventilation and partial visibility if desired.
Step 4: Insert the downspout or pipe directly into the tank’s opening. Add a screen or filter to keep out debris, and seal as needed.
Ideal for parks, schools, or public gardens, this installation educates while it hydrates, showing that rainwater is more than runoff, it’s a life source.
