Homeowners
The Eljen Geotextile Sand Filter (GSF) is a passive advanced onsite wastewater treatment system that provides homeowners with a reliable long-term performing septic system that is easy to maintain. The versatility of the GSF makes it ideal for new home construction or as a replacement in the repair for an old septic system.
The Eljen GSF Geotextile Sand Filter system is a cost-effective upgrade from other septic technologies. Unlike other systems that treat effluent only once, the GSF’s patented Bio-Matt™ pre-treatment process treats septic effluent twice. That means that the soil can absorb the effluent more easily, resulting in a better-performing system in a smaller area than other systems.
