Using a rain barrel is a great way to save water and keep some cash in your pocket. If you're on a public water system, you have to pay for the water you use, so consider it free water. It's also a great way to reduce stormwater runoff, which helps prevent erosion and pollutants like lawn fertilizers, animal waste and other chemicals from affecting the environment. It's also healthier to water your plants as it doesn't contain chlorine and other chemicals and is softer than using tap water.
Rain barrels come in a wealth of sizes, so there's something for everyone, whether you're collecting from a small or larger home or building. You install the rain barrel under a downspout where it will collect the water running off of the roof when it rains. The collected water is then useful to water your plants and yard, fill up a fountain, wash your car or clean any tools.

Below we've outlined some considerations when purchasing a rain barrel and offered suggestions of suitable choices for every situation.
What to Consider When Purchasing a Rain Barrel
Size: Most rain barrels usually come with a storage capacity of anywhere from 30 gallons of water to more than 100 gallons of water. The larger the barrel, the more water it will hold. To get an idea of how much water is produced during a rainstorm, for a 1,000-square-foot roof, every inch of rain that falls can result in around 600 gallons of rainwater. However, the average amount of water you collect is around 10% to 30%.
If you wish to collect a larger amount of water, with some DIY handiwork, you can connect two rain barrels. You can then retain the excess water that would typically overflow when the first barrel reaches capacity. Look for a barrel that can hook up to another.
Durable Lid and Screen: You want to make sure the rain barrel has a durable lid or a secure mesh screen that can't be easily removed by children or animals. Some rain barrels have both a lid and a screen. This prevents things like mosquitoes, leaves and other debris from getting into the contained water.
Overflow Precautions: You'll want to regularly monitor the rain barrel to prevent an overflow that can damage your home's foundation or create other problems, especially if you plan to be away for an extended period of time. To prevent this, you can disconnect the downspout and make sure the rain barrel is covered.
Another option is connecting an overflow valve to a garden hose, directing the flow of water away from your home. You can also purchase a downspout diverter and have it installed on the downspout. This allows the flow of water to return to the downspout once the rain barrel is full.
Ease of Use: If you will be using the rain barrel to water your garden, you'll want to make sure the spigot is near the bottom, making it easy to fill up your watering can. The last thing you want is a barrel with all the valves and fittings located at its back where you can't get to them or move the barrel once it's filled with water. Elevating the barrel on a sturdy stand makes it easier to use and you won't have to do much bending. Just make sure the stand is sturdy enough to hold the barrel once filled with water.
