Rain barrels are a sustainable landscaping practice that lets residents collect rainwater that runs off their roofs and store it for later use. The collected rainwater is not potable but can be used to water plants, wash vehicles, fill bird baths, wash pets, and more! In the United States, rainwater harvesting is becoming more popular due to its many benefits. It can protect our waterways by reducing stormwater runoff, strain on local aquifers, and some risk of flooding. The practice can also help homeowners by reducing their water bills and erosion issues!
A common misconception about rain barrels is that they need a building with gutters to work. However, rain barrels can be placed strategically under roof corners and eaves to capture rainwater through sheet flow. Water can also be directed from the roof to the rain barrel by a rain chain if the building does not have gutters or downspouts.
If you are interested in adding a rain barrel to your property, keep these tips in mind:
- All rain barrels should have a tight-fitting lid with a screened inlet to prevent mosquitos, leaves, and other debris from entering the barrel, an emergency overflow hose to allow water to escape when the barrel is complete, and a spigot to turn the flow on and off.
- Rain barrels should have a dark-colored body to prevent algal growth.
- When installing the rain barrel, elevate it 12-36 inches above the ground to ensure access to the spigot.
- Secure the barrel to stay upright, as a full 55-gallon rain barrel weighs over 450 pounds.
- The best way to care for a rain barrel is to use it. If the rain barrel sits full, the water will become stagnant, and water quality will decline.
