GeoMat Drainfield System

Traditional products only utilize a small portion of the drainfield each time they dose.
GeoMat utilizes the entire system every time it doses.     

GeoMat CRU files provide multiple design options for any application.

We are often asked if GeoMat can change a mound or at-grade to an inground. Quite often the answer is yes. 

Bob Berceau, co-owner of New Septic Solutions, is a CST and licensed designer. Bob has designed hundreds of GeoMat systems. 

If you need help getting started with our CRU files, or if a site has you questioning the best option to go with, contact us via telephone or text at 608-333-3610.

The Formula

GeoMat combines three critical components to prevent saturated conditions

Shallow Burial Depth      GeoMat ideal burial depth is 12" below the surface of the ground.

Even Dispersal               The shape and entangled plastic membrane spread water across the mat.

Max. Oxygen Transfer    Anaerobic bacteria can not exist in a dry, aerated environment.

The Foundation                                          

  • GeoMat is constructed so every dose utilizes the entire 39" wide mat.                                

  • The volume of wastewater per dose is less than 50 gallons.                    

  • Wastewater passes quickly through sand into the soil.                                   

  • The result; better treatment in a smaller area                                                    

History

Over 2,000 GeoMat systems installed in Wisconsin since 2018. ZERO failures. 

This can only happen when a product performs as designed. 

Authentication

GeoMat 2.0 load rate was proven in stringent NSF (National Sanitation Foundation) testing.

When a proprietary system is independently tested by NSF, the leaching system is

hydraulically loaded at the design loading rate every day. Odds of the design

loading rate happening daily in the real world is virtually zero.  

 

The design loading rate used to load the leaching system includes a peak flow, 

which includes a safety factor between 1.5 to 2 times the actual rate. In addition,

the NSF regime requires a high flow stress test be performed.

Length

Three bedrooms:  70 lineal feet 

Four bedrooms:    92 lineal feet 

GeoMat sections can easily spliced together  by placing a piece

fabric across the seams and tucking it under the sides of the GeoMat.  

Dimensions

GeoMat is 39" wide by 1" thick

GeoMat comes in 100 ft. rolls

A roll is 36"x36"x 43" high and weighs 70 lbs.

A roll easily fits in the back of a pickup 

Approved for

Conventional gravity systems

Conventional dosing systems

Conventional pressurized systems

Regular mound systems

Split-bed mound systems

GeoMat originally required installing a gravity filter and a pressure filter.

Installing a gravity filter is no longer required.

Lateral orifices range in size from 1/8" to 5/16" in diameter. If only one orifice plugs, it creates uneven distribution.If a gravity effluent filter is pulled without pumping the septic tank first, solids will flow

through the bottom of the filter case into the pump chamber and out the force main into the laterals. 

If a gravity filter is completely plugged, the water level has risen above the top of the filter. Everything

(solids, fats, oils, greases) floating above the top of the case will flood through the outlet into the pump chamber.

Every time the pump turns on and off, solids settle to the bottom of the lateral pipe(s) causing orifices

to plug. Plugged orifices cause uneven wastewater dispersal resulting in saturated, oxygen starved

conditions. The end result is reduced lifespan.

Understanding how septic systems fail

Septic systems fail when the soil becomes saturated with wastewater 

  • Saturated soil causes oxygen starvation stopping the flow of air into the soil. 

  • Saturated, oxygen starved ground creates anaerobic (does not need oxygen) bacteria. 

  • Anaerobic bacteria produce a black, jelly-like permeable substance referred to as biomat. 

  • As long as the ground remains wet, anaerobic bacteria will multiply in the oxygen-staved soil. 

  • This effect will continue until the entire drainfield is covered with biomat causing the system to fail.

Understanding why septic systems fail

The EPA states "Most systems fail because of inappropriate design or poor maintenance...." 

We respectfully disagree.

In Wisconsin, septic systems are overwhelmingly designed correctly.

In most instances, improper maintenance is due to property owners choosing to perform their own maintenance,

then neglecting to follow through. 

Septic system failure is often attributable to one or more of the following:

Using more water than the system is designed to dispose or in a timely manner:

Using large quantities of water in a short period of time (see ClearFlow Filter). 

 

Uneven wastewater dispersal

Pressurized systems are designed to utilize the enter drainfield every time they dose. They

do dose evenly from front to back, however they do not dose evenly from side to side. 

Sand, stone and alternative products do not significantly disperse water away from the point of contact. 

This causes hydraulic jetting, which creates saturated conditions at the point of contact. As a result, a biomat

forms at the interface of the orifice and the medium. This is why so many failed mound systems are completely

dry with no biomat buildup on the sides of the mound.

The system has four cells; each cell is 45' long x 39" wide

It was designed by Nick Klein with an assist from Bob Berceau of New Septic Solutions. 

The owners wanted to minimize size, limit loss of vegetation and be inconspicuous.
