A New Solution for Onsite Septic Systems:
We are proud to introduce the Advanced Enviro-Septic® Treatment System (“AES”) in Montana. Advanced Enviro-Septic® is the next generation of our effective and reliable Enviro-Septic® technology; certain systems have received Class I Certification under NSF International/ANSI’s Standard 40 for Wastewater Treatment Devices. Pending revision of its Circular 4 Design Standard, Montana DEQ has given AES product interim approval by formally issuing the following blanket deviations:
The following deviations to Montana Circular 4 Design Standards can be used for non-public wastewater systems (those that serve less than 25 people for 60 days) with residential strength waste and a design capacity of less than 2,500 gpd.
- DEQ-4, Standard 188.8.131.52: Presby laterals may be placed a minimum of two feet on center with zero distance between trench walls. The centerline-centerline distance between the two outermost pipe laterals shall not exceed 14 ft.
- DEQ-4, Standard 184.108.40.206: For the purposes of sizing, Presby lateral trenches must not be considered more than 48 inches wide.
- DEQ-4, Standard 13.2.3: Presby lateral trenches may use gravity distribution up to 48 inches.
- DEQ-4, Standard 13.2.4: When installing a Presby system, the absorption system size in square footage per Chapter 8 may be reduced in size by 50 percent for soil percolation rates less than 51 mpi and 25 percent for soil percolation rates between 51 and 120 mpi..
For application of AES to public wastewater systems (those that serve more than 25 people for 60 days and a design capacity of less than 2,500 gpd) or to systems with greater than residential strength waste, Montana DEQ will consider granting a variance.
We require individuals who wish to design or install an Advanced Enviro-Septic® or Enviro-Septic® System be certified by attending the Enviro-Septic® Design and Installation Certification Class. The class offers various design and installation configurations, troubleshooting techniques and tricks of the trade. To view the class schedule and certification options click on the ‘Training and Certification’ tab above.

In Montana, certification is required for all designers and installers. The classes are a great way to learn more about our product, even if you are not seeking certification. We strongly recommend regulators involved in the review and inspection of Advanced Enviro-Septic® systems take the certification training.
As part of certification, an assessment test is required. This should be taken only after viewing the class videos and reading the Montana Design and Installation Manual. The test is open book and is not timed. A passing score of 70% is required for certification.

Online Certification Test
After viewing the reading materials and training videos, follow the link below to the assessment test. We highly recommend that you download and print the Required Reading materials for the open book test which is not timed. If you receive a score of 70% or better, you will be emailed a copy of your Presby Certification Certificate, provided you give correct and accurate contact information to ensure proper certification. Please allow ten business days to process your test and deliver your certification.
The assessment test is only offered online. If you have special needs contact our Training Coordinator at 800-473-5298 x26.
