Just one inch of rainfall on 1,000 horizontal square feet of roof can result in 600 gallons of rainwater. Installing a rain barrel at your home is an easy, inexpensive way to collect that water for later use. Rain barrels collect and store roof water so that it can be used in place of tap water to:
- Water plants, gardens and lawns
- Wash pets, cars and patio furniture
- Fill fountains and birdbaths
Using rain water for outdoor chores will not only reduce your water bill, but will also have a positive effect on the environment. Rain barrels decrease the impact of stormwater runoff to streams which reduces the amount of pollution entering our waterways and minimizes sewer backups.
How does a rain barrel work? Rain barrels usually consist of a plastic storage container with lid, a system that diverts water into the barrel, an overflow that diverts excess water away from the house, a screen to keep out debris, and a water spigot to which a hose can attach. The rain barrel is connected into the downspout system, in order to capture and store a portion of the rain water produced by your roof.
Rainwater is ultimately better for your plants than tap water because it doesn’t contain any of the chemicals used to make tap water safe and clean. Plants don’t need sterilized water like humans. Natural rainwater is also soft and mildly acidic, so it helps plants grow and absorb important minerals from the soil.
Some localities offer rebates for the purchase and hookup of a rain barrel. Contact the stormwater contact in your municipality to learn what programs may be available to you or go to askhrgreen.org for everything you need to know about being green in Hampton Roads.
