GeoMat Leaching System

The most dangerous phrase in business is "we've always done it this way."

  • Traditional gravelless wastewater systems utilize a method referred to as 'storing water' in the leachfield.  

  • Gravelless systems repeatedly dose wastewater to the same small area while the rest of the leachfield is unused.  

  • Repeated dosing to the same spot with normal water usage results in the soil becoming saturated and oxygen starved.

  • Saturated soil stops the flow of air into the ground resulting in the formation of slimy, black, anaerobic bacteria called biomat.

  • Biomat prevents saturated soil from absorbing water, creating a domino effect, 

       covering one small area after another, making the field smaller and smaller. ​

  • When the entire field is covered with biomat, the only direction water

        can go is up through the ground surface or back into the house.      

The Solution

  • Shallow burial depth + even dispersal of water = maximum oxygen transfer

  • Oxygen results in biomat being transformed from anaerobic to aerobic.

  • A well aerated environment enhances treatment efficiencies.

The Science

  • ​GeoMat reduces storage volume so every dose comes in contact with more leaching system surface area​.

  • GeoMat relies on shallow burial depth and even dispersal of effluent to maximize oxygen transfer. 

  • Shallow burial depth and even dispersal of effluent maximizes oxygen transfer​ and increases the                                              flow of oxygen to the leachfield.

The Technology

  • GeoMat is comprised of fused, entangled plastic wrapped in fabric on top and bottom.

  • The shape and the membrane together draw water away from the point of application, across the entire mat

  • The thin 1" profile maximizes contact with the soil - which enhances oxygen transfer.

 

The Treatment

  • GeoMat + 12" of C33 sand provides maximum treatment of wastewater.

  • When effluent infiltrates the sand and soil, it pulls down air from above, allowing liquids or gas to pass through it.

  • Water travels quickly down through the sand beneath the GeoMat, resulting in different levels of the sand being

        saturated only briefly, if at all.

The Proof

  • GeoMat 2.0 load rate and hydraulic capacity were proven in stringent NSF testing.                         

  • When a proprietary system is tested by ANSI/NSF, or other similar testing authorities,                                                                 the leaching system is hydraulically loaded at the design loading rate every day.          ​

  • The design loading rate used to load the leaching system includes a peak flow,                                                                          which includes a safety factor typically between 1.5 to 2 times. 

  • In addition, the ANSI/NSF regime requires a high flow stress test be performed.

  • The loading rate applied under NSF testing protocol should never happen in the real world.

  • Conventional pressurized systems

  • Regular mound systems

  • Split-bed mound systems

Dosing Systems: The quality of a pressurized system at substantially less cost 

  • GeoMat only requires 37" insitu soil for inground installations

  • Dosing systems use 2" Schedule 40 pipe with 1/2" orifices drilled at 4 and 8 o:clock

  • Orifices are spaced at 12" intervals; they do not require orifice shields

  • Unlike pressurized systems, dosing systems are approved by counties, saving time and money.

What's your time worth?

Do you want more time to do more work or do want more time to do less work?

You can start planning what to do with the extra time you'll have by installing GeoMat.
