About Us


Michael and Dawn Rohrs were born and raised in Northern Oklahoma.  They  spent 10 years in Houston working for the oil industry when Dawn asked to be transferred back to OKC in 2014 so they could be closer to their families.  However, after the oil downturn in 2015/16 they decided it was time to diversify.  They started Cyclone with just one excavator and installed 11 septic systems that first year.  In 2018 they started pumping septics and in 2019, they expanded to manufacturing.  By 2019, they were installing nearly 200 systems per year.

They decided to slightly step back from installing in 2020 and started selling tanks to other certified installers.  Today, they have a facility in Guthrie where they manufacture around 500 aerobic tanks per year with 2/3 being sold other installers.


Dawn is adamant that consumer education is paramount to improving our industry and protecting the environment.  For that reason, she is on the OOWA board and also does training for installers, realtors, homeowners and builders.


This is a family affair.  You are likely to see Dawn, Michael or their sons, Austin & Cody, on a job. So, what are you waiting for? Give us a call!
