Rainwater Harvesting Rebate Program Updates

We have made two important updates to the Lost Pines GCD Rainwater Harvesting Rebate Program to give property owners more flexibility and clarify requirements for potable systems.

Apply More Than Once, Up to $5,000

Previously, properties were limited to one rebate application. Under the updated program, applicants may submit additional applications for the same property until they reach the $5,000 maximum rebate per property.

For example, if you previously received a $2,000 rebate, you may apply for additional eligible rainwater storage and receive up to another $3,000 in rebates.

New Requirement for Potable Systems

Applicants installing a rainwater harvesting system that will provide potable water must communicate with their municipal water supplier and comply with the supplier’s applicable backflow prevention requirements.

These updates provide greater flexibility for residents who want to expand their rainwater harvesting systems while helping potable systems meet local water supplier requirements.

Interested in applying? Remember, applicants must attend a Rainwater Harvesting 101 workshop and receive approval before installing their system. Learn more by calling (512) 360-5088 or going to the Rainwater Harvesting Webpage.
