The Hydro-Action Aerobic Treatment Unit invented by Gig Drewery in 1989. Bruce Craig ran the operations when
they first started in Texas. They were the most significant treatment plant manufacture in Texas. Then some lawsuits
were filed over some stupid patents that are not even worth the paper they are on. Gig, and Craig had a massive
operation as well way too many employees one time they had 15-20 engineers you don’t need full-time engineers in
this business those mistakes caught up with them. They owed Gast somewhere in the neighborhood of 660k, and AK
who made the cones over a million so in the bankruptcy AK got them. Now a wholly owned subsidiary of AK
They are a leader in fiberglass and polyethylene products for the wastewater market. AK Industries is a leader in the
manufacturing of lift stations and other wastewater tank applications they also rotomold the cones the other
manufacturers put in their systems.
• Producing a top-quality line of products with consistent engineering and production detail
• Continued, reliable customer service
• Providing the “Best Value” available
Since 1989 Hydro-Action has been in the aerobic septic system business. Hydro-Action was made in Texas until
2004-2006 and was owned by Gig. They are prevalent in the Midwest, and east coast areas not a lot of new systems
are being put in southern states any longer. Do to when AK received them I don’t know if they wanted to be in the
aerobic septic system manufacturing business and didn't know what to do. So it was a back burner project, and from
what I gather they are a not an aggressive company. When Hydro-Action was located in Lumberton, they were
being put in the ground left and right in Texas, so you see them in Texas, Louisiana, and other southern states. AK is
making a push back into these states.
The unit itself is well made and does a great job treating wastewater it is one of the top tier units with great diffusers
and comfortable access design that is service friendly. It is easier to service the diffusers than systems that are of a
similar design Clearstream being the big one. It is close in design to Clearstream, and Ecological Tank Aerobic
septic system. These units use Gast Rotary vane septic air pumps or a Hiblow septic aerators.
