Catch water while it is raining to use on your landscape when it is not!
Rainwater harvesting is the collection and storage of rain, usually from an impervious surface like a roof. Harvesting rain to use later can be helpful for efficient landscaping, but it can also be fun!
Just 1 inch of rainfall on a 2,000 sq. ft. roof can produce 1,250 gallons of water!
Catch up on rainwater harvesting basics like how to calculate how much water your roof will produce in a year, different types of rain barrels and cisterns, how to keep mosquitos out of your barrel, basic safety, and more!

BUILD YOUR OWN RAIN BARREL
Building your own rain barrel is easy! All you need is a food-safe container, a few supplies from the hardware store, and common household tools. Watch one of the videos below to see a step-by-step demonstration of how to build your own rain barrel.
After building your barrel, you can choose to decorate it by painting it or cover it if you like. After that, hook your home-made barrel up to a downspout or put it below a roof valley, and it is ready to go. Just make sure you close your spigot before that first rain!
Rainwater is the BEST water for plants and harvesting from a rainfall event is a great way to reduce the demand on our water supplies!

Contrary to popular belief, rainwater harvesting is not illegal in Texas. However, check with your HOA before you install your barrel. They may have rules on where it can be placed or what it can look like. Generally, keeping it out of sight in the backyard is a safe bet.
