Eljen GSF Installation Video

To see an installation overview of the Eljen Geotextile Sand Filter

The Eljen GSF is a cost-effective upgrade from other septic treatment technologies. Comprised of a proprietary two-stage Bio-Matt(TM) pre-treatment process, the geotextile modules apply filtered septic tank effluent to the soil, increasing the soil’s ability to accept the effluent and increase the long term acceptance rate (LTAR). The result is a superior performance in a smaller soil absorption area.
