What is the purpose of a Double Compartment Septic Tank?

Aside from differences in capacity between the one and two compartment poly septic tanks, the way in which water flows and collects in your tank is distinct. A second compartment allows more room to settle the solids and liquids in the tank.

In a single compartment tank, one chamber that holds all liquid, sludge and scum. Adding a second compartment provides an additional area for you sludge and liquid to exist. Typically the two compartments are separated by a baffle partition. The partition opening allows for a select amount of liquid to flow into the secondary area. Once liquids inside the septic tank reach the height of the opening, flow into the second chamber begins.

This permits solids more time to settle, allows extra storage space septic waste. As opposed to a single compartment, the extra compartment gives you more space and more time before you need to empty the tank.
