Average Home Could Collect 25,568 Gallons of Rainwater Annually

Have you ever wondered how much water comes off of your roof in a major rainfall event? What about over the course of a year? Let’s assume the average home in Navarro County is 1200 square feet and that the average rainfall is 38 inches annually. For every square foot (horizontal square foot not roof area) we collect 0.623 gallons per 1 inch of rain. So the average home would collect 747.6 gallons per 1 inch of rainfall. If we figure 38 inches annually and a 90% collection efficiency, then the average home could collect 25,568 gallons per year! That water could go to a variety of uses. As the state of Texas faces increased population growth and demand on water resources, rainwater may be making a comeback. Want to know more?

A Rainwater Harvesting Workshop is scheduled for Thursday, May 6 from 5:30pm to 8:30 pm at the Sumner Family Property, north of Blooming Grove, TX. Highlighting the event will be Dr. Dotty Woodson, Extension Specialist for Water Resources who will present on the basics of rainwater harvesting and guide us in putting together rainwater barrels. A limited number of rain barrels will be available for purchase on a first come, first serve basis. Also, as part of the program we will view a 3,000 gallon rainwater collection demonstration as well as a unique project that is funneling rainwater to a surface tank. Directions: Take Highway 22 to Blooming Grove, TX. On the east side of town, turn north onto Pecan Street (this turns into NWCR 1420). Go 1.2 miles and turn left into the drive, look for signs.
