3rd party independent testing at the Massachusetts Alternative Septic System Test Center, an EPA / NSF certified test facility, confirmed that the GSF provides advanced treatment of septic tank effluent to better than secondary levels. This has allowed the GSF to receive approvals from some states with up to a 70% reduction in the size of the wastewater disposal area as compared to conventional stone and pipe systems. This provides regulators the assurance of a reliable easy to maintain system with long-term performance that their customers require.
Benefits of the Eljen GSF System
Site Flexibility
The Eljen Geotextile Sand Filter system can be designed to accommodate a wide variety of soil and site conditions. From sandy to clayey soils, the GSF can be installed in trench or bed configurations, level our sloped terrain, in-ground or mounds, and even curvilinear module rows to avoid rock outcropping or old growth trees.
Designed for Superior Performance
The unique design of the Eljen GSF reduces the biological soil clogging that occurs in other septic systems by its propriety two-stage Bio-Matt™ pre-treatment process that delivers a better than secondary aerobic effluent to the soil.
Longevity and Reliability
The GSF is time proven with over 25 years in the onsite wastewater industry in both residential and commercial applications. Our high success rate over other technologies is due to the large infiltrative surface area contained in each GSF module. Give your customers the confidence and reliability they require from their septic system. Give them the GSF!
Environmentally Friendly
