Common builds
Rain catchment kit. Tote with a screened inlet, sealed top hatch, outlet adapter for a garden hose and overflow plumbing. Often paired with a first-flush diverter under a downspout.
Raised garden bed cut. Tote cut horizontally into two halves with drainage holes, giving two shallow beds with the cage's footprint.
Aquaponics starter. Cut tote with a grow bed, pump and return plumbing. Long-form build guide: aquaponics from an IBC.
Secondary containment. Cut-down tote used as a spill pan under a drum or small tank.
For any food-growing or drinking-water use, ask what the tote previously held before you buy.
