Pro tip: If you’re hoping to harvest rainwater directly from your gutters, look for rain barrels that are flat on one side so they sit flush against your house.

Rainy season is nearly upon us, Indy. With ample precipitation in the forecast for the next couple of months, you may be wondering if the next storm is going to flood your crawlspace or basement again.

There’s a way to make use of some of that extra rain, promote sustainable water practices, and save money on your next water bill. Let’s break it down.

Rainwater harvesting explained

Building a rainwater harvesting system is an easy way to provide non-potable water for your plants. The best part: After some small start-up costs, it’s free, and we love free.

The system collects water off non-permeable surfaces like your roof and funnels it into a storage chamber, like a rain barrel or cistern, to be used when rain isn’t in the forecast as frequently — i.e. this summer.

A general rule of thumb: One inch of rainfall produces about 997 gallons for an average 1,600-sqft home.
