How to Build a Rain Barrel

Trash Can Rain Barrels

Family Handyman

You can make cheap, functional rain barrels with trash cans and simple PVC plumbing and electrical conduit fittings. Line up as many as you need to meet your watering needs and save water around your house.

To begin, place the drum near a downspout, drill a hole in the side near the bottom and screw in a drain valve. That’s an OK installation if you plan to run a soaker hose to your garden. But if you want to use a wand or a spray nozzle, you’ll need to elevate the DIY rain barrel on a stand for more water pressure. Water is heavy (55 gallons weighs 440 lbs.), so use 4×4 treated lumber for the legs and secure everything with construction screws or stainless steel lags. But don’t place the stand on soft ground. You could kill somebody if the rig toppled over. If you have large gardens and want to store more water, double-size the stand and add a second barrel.
