Presby EnviroFin® Septic Systems

Presby EnviroFin® system’s revolutionary wastewater solution is especially useful when working on challenging projects with a zero lot line or difficult terrain.

Presby EnviroFin® system is one of the simplest and most affordable water treatment solutions ever designed.

The Septic System Details

1. Perforated Pipe (Air Duct)

Allows air to flow lengthwise into the fibers and system Sand to promote bacterial growth

2. Fin Distribution Unit (FDU)

Settles and breaks down suspended solids
Equalizes flow between units
Distributes effluent into the Treatment Fins

3. Skimmer Tabs

Prevents grease and suspended solids from leaving the FDU
Protects coarse Green Fibers and geo-textile from clogging

4. Air Ports

Allows air to enter the Treatment Fins to promote aerobic bacterial growth

5. Coarse Green Fibers

Filters and digests more suspended solids
Protects outer geo-textile bacterial treatment surface
Creates massive bacteria treatment area

Developed by Presby Environmental, Inc., this advanced treatment system relies on passive, non-mechanical filtration for exceptional treatment and dispersal of contaminated wastewater. As a result, this powerful treatment system:

Is very affordable to install
Requires almost zero maintenance once installed
Offers unmatched endurance

But how does this revolutionary technology actually work?

EnviroFin^® Septic System Treatment – Under the Presby Hood

The EnviroFin^® product uses a 10-stage treatment process to transform contaminated effluent into safe groundwater.

Stage 1: Warmed wastewater enters the fin distribution unit (FDU) where it is cooled to the same temperature as the surrounding soil.
Stage 2: Solids that are suspended in the wastewater begin separating from the cooled effluent.
Stage 3: Skimmer tabs prevent left over grease and other suspended solids from leaving the fin distribution unit.
Stage 4: Tiny perforations in the FDU permit wastewater to seep into a network of randomly-oriented fibers that remove even more suspended solids.
Stage 5: Air ducts at the top of the fin permit outside air to flow along the length of the piping and into the fiber network. In addition, surrounding System Sand promotes bacterial growth that further breaks down contaminants and other waste matter.
Stage 6: The internal fibers increase the surface area of the bacterial layer, allowing the EnviroFin^® ;unit to maximize its treatment process.
Stage 7: The wastewater then passes through geo-textile fabrics. This process helps to cultivate an even larger bacterial surface for additional waste decomposition.
Stage 8: System Sand helps to wick away excess liquid from the geo-textile fabrics, which promotes greater airflow and increased aerobic bacterial growth.
Stage 9: System Sand then finishes “polishing” the effluent so that it meets the rigorous tertiary treatment standards established by third-party certification organizations like NSF and ANSI.
Stage 10: Fluctuating liquid levels coupled with uninterrupted air supply help to boost the bacterial culture’s efficiency so that the treated effluent is safe for dispersal as groundwater.

At my firm, ORR Design Office, Inc., we design site-specific high-end custom homes throughout the Northern California region. We often design on parcels that require on-site septic systems and associated leach fields. It is not uncommon for us to encounter poor soils that have in the past required very expensive systems to treat waste water. Or, we find that...Read More »

My husband and I bought a property in Yuba County and found out after the fact that our septic system wasn't working properly. We called about a dozen people and the prices to repair our system was outrageous, we spoke with a family engineering friend about our dilemma and he suggested looking into the Presby Enviro-septic system. I called and spoke...Read More »

Whitney Mello

Outstanding service and went above and beyond in helping my wife and I put in a system that not only was a superior product but a helluva savings vesus the conventional sand filtration system. Strongly recommend the Presby system to anyone needing a sand system. Cant say enough about the team at NexGen.

Jerry Sinkey

They designed a septic system that the county approved when the other engineers said it was impossible. Ian was a pleasure to work with and we highly recommend them.
