The Eljen GSF® (4-feet long by 2-feet wide by 7-inches high) fits in standard trenches and can be configured to fit any infiltration area shape where site restraints and hydraulic needs are a prime consideration.
Engineered For Superior Strength
- Provides advanced treatment in 50% less space than standard untreated systems
- Proven reliable performance eliminates the need for complicated maintenance
- Smaller size and streamlined design significantly reduces overall system costs
- Long-term leaching capacity is 2 to 3 times that of similar systems
The only system that pre-treats leach field effluent with a patented two-stage biomat filtration process
Made from lightweight recycled material, the GSF® leach field is engineered for superior strength. The Eljen GSF®, with its pre-fabricated modular units comprised of geotextile fabric and cuspated spacer cores, provides an alternative to conventional stone and pipe or chamber leaching systems.
Substantial effluent pre-treatment occurs within the two-stage biomat which develops on the 65-square feet of geotextile fabric, which is 7 times the area of soil interface.
This internal passive pre-treatment protects both the soil’s long-term acceptance rate (LTAR) and groundwater quality while providing a reduced system footprint. At 7″ thick, the GSF provides the lowest product profile, thus reducing the system’s finished grade.
