What Is A Septic System?

Simply, a septic system is a two-part sewage treatment and disposal system buried in the ground.

It incorporates a septic tank and a sewage treatment area. It can have pumps, filters, and other components, depending on your septic site and residence needs.

First, the raw sewage usually flows by gravity into the septic tank (commonly a concrete box), where large particles settle to the bottom and some decomposition takes place. In a second stage, the effluent flows from the tank into the distribution box, and then it gets distributed evenly to the filter system (pictured a GSF system - Geotextile Sand Filter) and leach field where it further decomposes before slowly soaking into the soil.

The Eljen GSF System

When your septic system installation requires more performance in less space, the Eljen GSF delivers.

With Eljen’s patented two-stage Bio-Matt™ pre-treatment process the GSF applies a better than secondary treated effluent to the soil, increasing the soil’s acceptance rate. This results in superior treatment in the smallest area possible.
