About Gig & Trina
Gig Drewery, alongside his wife Trina, boasts an impressive legacy spanning over four decades in addressing onsite wastewater challenges. Their journey began in the early 1980s when they began installing aerobic treatment units (ATUs) in East Texas where they played a pivotal role in obtaining state approval for ATU usage. Gig is a licensed Texas installer II, licensed maintenance provider and a licensed site evaluator. They went on to found Hydro Action and transitioned from installing to designing and developing NSF-tested and certified ATU products.
Gig’s contributions extend beyond innovation; a number of his patents have become public domain and continue to shape the industry. As a founding board member of the National Onsite Wastewater Recycling Association (NOWRA) and the inaugural president of the Texas Onsite Wastewater Association (TOWA), Gig has left an indelible mark on the sector. Additionally, he has lent his expertise to the NSF joint committee for a number of years.
The couple’s enduring commitment to addressing onsite wastewater challenges has culminated in the development of the groundbreaking innovative RioVation® BioMaze® technology which converts septic tanks into Biofilm Reactors otherwise known as an ATU’s. Gig and Trina’s unwavering passion underscores their dedication to finding sustainable, cost-effective solutions for the industry and the environment.

Soil is an Excellent Medium for Wastewater Treatment
Estimated that less than 1/2 of the soils making up the United States are suitable for Wastewater Treatment
The Soils that are suitable for Wastewater Treatment live in very unpredictable and hostile environments
We can keep rolling the dice and leaving more than 4 billion gallons a day of septic effluent treatment to chance in the soil
We move the treatment into the tank where ~90% of the waste can be removed and leave the remaining ~10% for the soil to finish
The RioVation team is dedicated to designing and manufacturing practical and affordable solutions for onsite wastewater treatment challenges which impact people and our environment. We care about the contractors we work with and design treatment solutions for, their customers, and the environment that we all share and value.
