2. It saves water and money.
Water-intensive landscapes and green lawns cost a lot of money. In dry climates and during the summer, homeowners can use as much as two to four times more water than usual, according to the Environmental Protection Agency. A rain barrel’s “water catch” can collect 1,300 gallons of water during the growing season. And irrigating with rainwater could reduce your water bill by 30 percent or more.
One inch of rainfall on a 1,000-square-foot roof yields over 600 gallons of water. Even in dry areas, less than an inch of rain can fill a rain barrel. Cutting back on water use for your lawn and garden not only reduces your water footprint, but it can also reduce your water bill.
3. Water restrictions don’t apply.
If you collect rainwater, you’ll be able to keep watering and nourishing your garden all summer long, even when water advisories are put in place to limit residential water usage.
4. It helps protect your home from water damage.
Rainwater from a big storm can flood your basement or create a build-up of moisture next to your foundation, leading to damp patches and mold. Rain barrels help prevent these potentially dangerous problems by protecting the already-saturated ground from excess water.
5. It’s helpful to your local water treatment facility.
Urban areas covered with concrete, tarmac and buildings create runoff during heavy storms, which can carry pollutants into waterways. Collecting rainwater can reduce the amount of runoff and prevent some of that pollution from reaching waterways near you.
Additionally, runoff from rainy and snowy weather can cause flooding downstream and overflow at sewage treatment plants. Collecting the rainwater that lands on your roof might seem like a small effort, but it helps minimize flooding and leaks further downstream. If you don’t need a full rain barrel to care for your lawn and garden or other activities, you can slowly release excess in between storms. This allows the water to soak into the ground instead of running into storm sewers.
