Collecting rainwater in water barrels is not only beneficial to your garden but to the pocketbook as well. Just think how much water runs off the average roof, hundreds of gallons everytime it rains. I want my garden to look good in the summer, but the water bill just kept getting higher. I have been using water barrels for the past few years and I love them. My first investment was in 2 ready made rain barrels from an online gardening source. The cost was ridiculous. I started doing some research on how I could make my own rain barrels and save some money in the process. Here is a couple of the links I found for instructions on how to build a rain barrel. It was so easy we made four!
My husband purchased 4 used food quality barrels from a military surplus store for about $15.00 a piece. It is very important that they are food quality, ours were used to store olives. Any container that was used to store chemicals will probably have residue that could harm your plants and the environment. We invested about $30-$40 in parts that we purchased from our local home improvement store for an overall investment of $100.00 for 4 barrels. The parts are easy to find, they are just common plumbing parts. I don’t know if you have priced ready made rain barrels but they can be as much as $100.00 a piece. The project wasn’t too time consuming. It took about 1 1/2 hours to complete. As you can see the instructions go one step further and show adding a spigot with a hose to make filling your watering can easy. I fill my watering can by unscrewing the lid from the container and dipping the watering can in the top. You could also attach a hose to the spigot if you elevate the containers to run off the excess water when the containers overfill.
