The Non-Aggregate Leach Field System with new Bio-Matt Fabric.  

	In-Drain system pretreats effluent with a two-stage biomat
	System maintains greater long term leaching capacity
	Requires much smaller area than conventional systems
	Lower site impact and less offsite fill required
	ends worries about dirty stone and stone dust
	Made with lightweight recycled materials
	Excellent documented long term track record
	The leach field system with a 10 year warranty

   

Here's how it works... 

Only the Eljen In-Drain System "pretreats" effluent with a two-stage biomat. 

 
 
  Conventional Systems...
      have a single biomat forming at the soil interface.  In-Drains offer 2 biomat layers...
      1) Primary surface on fabric, 2) Secondary a 6": sand Layer. 
 

Compare New Bio-Matt Fabric vs. Soil Interface 
 
 

Recent Studies have shown that the hydraulic conductivity ration (HCR)of nonwoven fabric has a stable long term permeability in contact with sand. Bio-Matt fabric in standard In- Drains offers a comparable environment environment to soil for biomat growth and presents no masking effect on infiltration capacity. Many years of field experience confirm the long term acceptance rates (LTAR) used in sizing In- Drain leach field systems.  1989 study by Geoservices Inc., Norcross, GA.
