Eljen System

The Eljen GSF Geotextile Sand Filter System is a cost-effective upgrade from other septic technologies.  Comprised of a proprietary two-stage Bio-Matt™ pre-treatment process, the GSF Modules apply a better-than-secondary aerobic effluent to the soil, increasing the soil’s ability to accept the effluent.  The result is a superior treatment in a smaller absorption area. Ken White Construction has been installing Eljen Systems in the Ottawa Area since they were first introduced. It has quickly become our septic installation of choice!

Intended Use: 

  • Sites that require smaller systems due to lack of space
  • Cost-effective solution


  • Tested and Certifed by NSF to NSF Standard 40
  • Independent and third party testing shows the Eljen GSF treats to better than secondary treatment
  • Pretreats effluent with a two-stage Bio-Matt™ process
  • Greater long-term performance
  • Requires a much smaller installation area than traditional systems
  • Patented products and technology
  • No stone required
  • Lower site impact
