About Gig & Trina

Gig Drewery and his wife, Trina, have been solving onsite wastewater issues for over 30 years. In the early 1980’s Gig and Trina began installing aerobic treatment units in east Texas and were instrumental in getting ATU’s approved for use in the state. They soon began designing and developing NSF tested and certified aerobic treatment unit (ATU) products under the company name Hydro-Action.

About Gig

Over the years many of Gig’s patents have become public domain and are still in use in the industry today. He was a founding board member of the National Onsite Wastewater Recycling Association (NOWRA), the founding president of the Texas Onsite Wastewater Association (TOWA) and has served on the NSF joint committee. Gig and Trina’s continued passion for solving onsite wastewater treatment issues facing the industry and the environment has led them to develop the innovative RioVation® BioMaze™ Biofilm Reactor product line.

Gig is passionate about solving the wastewater problems which impact the health of people and the environment that exist in the USA and world-wide.
