Septic Tanks

Septic Tanks in Washington, DC

The fundamental function of the septic tank is to remove solids from raw wastewater. This process is known as primary treatment.

At this stage 60%–80% of total suspended solids (TSS) are removed from the wastewater and almost 80% of the FOG is removed. Of the solids removed from the wastewater, some are digested and others are stored in the tank. Up to 50% of the solids retained in the tank decompose; the rest accumulate as sludge and scum and must be removed periodically.
