Rainwater Harvesting

Free Healthy Lawns and Healthy Waters class, April 14, 2026.

Texas A&M AgriLife Extension Service’s Healthy Lawns and Healthy Waters Program will host a face to face residential rainwater harvesting and turf management training April 14, 2026 for Williamson County.

The free event will be on April 14, 2026 from 1:00 to 5:00 pm at the Round Rock Utilities and Transportation Department, 3400 Sunrise Rd, Round Rock, Texas.

Attendees can RSVP online and may contact John Smith, AgriLife Extension Program Specialist, Bryan-College Station, at john.smith@ag.tamu.edu or 979-204-0573 with any questions. Those who RSVP for the event will receive updates and materials including the link related to the training via email. Everyone attending needs to register online.

Attendees can submit a soil test by picking up soil test bags and dropping off their soil sample and Urban Information sheet at the AgriLife Extension offices in Williamson County prior to or by one week following the meeting.  Also, you can bring your soil sample to the program.

The training will include information on how to understand soil test results and nutrient recommendations so residents can interpret results once the analysis is emailed to them.

There will be NO  RAIN BARREL SALES in 2026 due to construction on-site at our office. 

 

You can purchase barrels from any vendor of your choice and still use the rain water collection rebate!

Here’s the Top Reasons why to collect rain:

  1. It’s free!
  2. Rainwater is always better for plants than treated tap water, due to its nitrogen content.
  3. Collecting rainwater helps prevent erosion.  If you don’t have specific plants or gardens to water, you can capture the water and release it slowly over the days following a rain storm.  Releasing it slowly allows more water to penetrate the ground, and again, prevents erosion–less of your soil will flow off the property with the water!
  4. It’s tax-exempt!  Rainwater harvesting components are tax-exempt per state law.
  5. There’s a rebate from the City!  
  6. Rainwater collection IS permitted within City limits.  HOAs cannot prohibit collection per Texas State Property Code 202-007.
  7. Another free and more consistent water source to collect is your air conditioner condensate!  Collect it in the same barrel as your rainwater for continued water savings.  During hot weather, our air conditioners are running more than ever, creating that little stream of water throughout the day that keeps the side of your yard wet and the grass green!  This is basically distilled water that can be used the same way water rainwater can.
  8. Water can be used to fill ponds, birdbaths, water gardens, or slowly released to reduce erosion.
  9. Barrels can be purchased from many places locally!  See the listing below*
