The idea is to place water collection devices under the eves of your house and collect water during large rain events. This water can accumulate quickly and depending how much is used to water plants, it can last a long time.
- You can check around town for old barrels, wooden or plastic. These can hold a large amount of water. It may be nice to elevate the barrel and install a spicket on the bottom of the barrel. The barrel can them be opened and closed like a faucet to fill watering cans, etc.
- Five gallon pals that have been cleaned out also make great containers. They are smaller and easier to carry around.
- You can also use something like an old cast iron bath tub or a trough from a farm supply shop.
