Planning for Your Commercial Septic System
Commercial septic projects or even large residential projects require a different skill set from the average septic system. From a design fit to purpose to an installation that works for the site, Dawn is one of a handful of installers in Oklahoma willing to tackle small public systems and the extensive permitting process that can come with them.
Large projects involving more than 1500 gpd of flow can involve months of planning and permitting. Bringing us in before construction starts can save you time and headaches once construction starts. Wedding venues, concert venues, MMJ grow operations, restaurants, RV parks, office parks, industrial parks, schools, municipal buildings… we’ve done it.
The Commercial Septic Project Process
The state of Oklahoma divides commercial projects into 3 categories.
- Less than 1500 gpd and less than 1.5 BOD
- Over 1500 gpd but less than 5000 gpd or less than 1500 gpd and over 1.5 BOD
- Over 5000 gpd
We provide design and installation services for systems that fall into categories 1 or 2. Both categories can require an alternative review for approval by the DEQ.
The permitting process for systems in category 2 can involve a lengthy and involved permitting process. Dawn has successfully submitted and received approval for countless projects.

Custom Residential Septic Systems
Most residential wastewater projects are straight forward. That’s why there are so many installers that do them. However, surprises can pop up that derail a homeowner or developer’s plans. Dawn has rescued multiple residential projects that other installers have walked away from due to the complexity. These projects will often require an alternative review by the DEQ. The most common examples of this are:
- The home is built on a lot smaller than a half acre.
- Multiple homes need to be served by the same system.
- Very large homes that exceed normal designed flows or available space
Dawn knows the state regulations better than most and, therefore, knows when there may be options available others haven’t thought of. She’s also willing to look outside the state to see what technologies are available and champion those for DEQ approval.

Last week we had an amber alarm on our aerobic septic system. We contacted Cyclone Septic to troubleshoot the issue and they arrived the next day, inspected the system, discovered that a clogged filter and failed aerator were the culprits. … More The filter was clean and the aerator was rebuilt that day brining our septic system back up to standards. The technician also pointed out that the system needed pumped, so the next week we booked a pumping. The pumping crew was great! They arrived on time, pumped the system and took the time to explain how the system worked to me. I highly recommend this company for all of your septic needs! -
