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.
