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.

Bryan ★★★★★ September 2026
Maintains our septic system. GREAT company. Did the full install on our new home. Never had one problem. Does a full inspection every 6 months, replaces sprayer heads when needed. Called several times about advice on maintenance - great … More help and very knowledgable. I am so glad our builder picked this company! UPDATE 9/3/2026 - Got to meet the owners Dawn and Michael today! What wonderful people and so responsive to their customers. They did a smoke test to see if there was any leakage due to recent issues and recommended an extension on two exhaust pipes on the roof. Their installed system was working perfectly after 5 years! I've also gotten Septlink installed by them last year. Highly recommend. It monitors the whole system and alerts me and them when there are any problems. No more guessing games whether something is wrong, and I sure want to know when a pump or aerator issue is happening BEFORE "other" EXPENSIVE problems happen (if you know what I mean). In all my years, this is the best company I have ever had the pleasure working with and the owners are exceptional people. -
