WaterSense Labeled Texas Landscape Irrigation Auditor (TxCLIA) Certification Program

What is WaterSense?

WaterSense® is a partnership program by the U.S. Environmental Protection Agency (EPA) designed to encourage water efficiency in the United States. The WaterSense label offers people a simple way to use less water by helping them easily identify and choose water-efficient products, new homes, and services..

WaterSense only labels irrigation professional certification programs that certify experienced irrigation design, installation/maintenance, and auditing professionals. Certified professionals must demonstrate their ability to assess critical soil/water/plant relationships and resulting impacts on irrigation system efficiency. They must complete continuing education requirements and renew their certification periodically to confirm their qualifications and demonstrate awareness of recent innovations and technology developments.
