About Eljen:

Established in 1970, Eljen Corporation created the world’s first prefabricated drainage system for foundation drainage and erosion control applications. In the mid-1980s, we introduced our Geotextile Sand Filter products for the passive advanced treatment of onsite wastewater in both residential and commercial applications. Today, Eljen is a global leader in providing innovative products and solutions for protecting our environment and public health.

The Eljen system is a cost-effective upgrade from other septic technologies. Comprised of a proprietary two-stage BIO-MATT pre-treatment process, the geotextile modules supply better than secondary septic tank effluent to the soil, increasing the soil’s ability to accept the effluent.
