Eljen GSF - Model A42 - Geotextile Sand Filter - Brochure

The Eljen GSF (Geotextile Sand Filter) is an alternative onsite septic leachfield system. Each GSF Module is made up of geotextile fabric and a plastic core material that work together to provide vertical surface area and oxygen transfer. The GSF System applies secondary treated effluent to the soil, increasing the soil’s long-term acceptance rate. A Specified Sand layer provides additional filtration, and prevents saturated conditions.
