So, you've taken the step of diverting and collecting the rainwater that falls on your roof. This is an excellent idea—helping you make the most of this natural resource and use it more wisely on your property. But what next? Many people stop at the stage of collecting harvested rainwater in a barrel or butt. But thinking about where the water goes next can help you make the right choices for water management in your garden.
The most obvious way to make use of the rainwater from your roof, perhaps, is to direct it from the collection vessel into an irrigation system for your garden. In certain instances, it may be possible to use gravity to divert water to an irrigation system. Water, of course, flows downhill. Raising a barrel or butt off the ground may be sufficient to gravity feed water to irrigate containers, planters, beds, or your vegetable plot.
