Having water where you need it can make a big difference on a farm. My main reasons for collecting rainwater were simple: provide a water source for my bees, water my fruit trees, and have water available for everyday chores.

Rather than let all the runoff from my shed roof go to waste, I installed a gutter and routed it through a rainwater diverter into a food-grade barrel. It’s a simple off-grid setup that puts rainfall to work.

Watch my shed gutter and rain barrel setup to see how it goes together.

• VYH 3/4-inch rain-barrel spigot kit, provides an outlet for filling buckets and watering cans.

A Water Source for My Bees

The bees were my biggest reason for starting this project. Bees need water, and having some stored at the farm gives me a convenient supply for keeping a bee waterer filled.

The barrel stores the water; a separate shallow waterer gives the bees somewhere to use it. Stones or other stable landing surfaces above the waterline let them reach the water without falling in. Keeping that waterer clean and checking it regularly are still part of the job.

Water for the Fruit Trees

My fruit trees were another reason to capture rainwater. When they need supplemental watering, having a barrel available means I can fill a bucket or watering can without bringing every bit of water from somewhere else.

It won’t replace rainfall or meet every watering need, but stored runoff can help bridge the gap between showers. How far it goes depends on how much rain falls, how much storage is available, and how much the trees need.

Water for Everyday Farm Chores

Not every job requires drinking water. Rinsing muddy boots, washing dirt off tools, and other outdoor chores are practical uses for collected rainwater. Having a supply nearby can cut down on hauling water just to handle a small task.

Hand washing was also one of the uses I had in mind, but that needs an important distinction: untreated roof runoff isn’t reliably safe for washing hands. It can pick up bird droppings and other contamination. For hand washing, use clean running water suitable for that purpose and soap, especially before handling food or tending a cut. A food-grade barrel does not make the collected water safe to drink or wash with.

Starting Small and Adding Storage

In the video, you’ll see three barrels on a pallet, but only one is connected. Adding more storage is a future step.

For now, the benefit is straightforward: catch some of the water already falling on the shed and keep it available for useful jobs. A rain barrel won’t drought-proof the farm, but it can make caring for bees, watering trees, and getting chores done a little easier.
