Septic System Construction

 A septic system is a convenient, cost efficient, and   safe method for treating and disposing of household   wastewater. A septic system is comprised of three   main components; the septic tank, the leach field,   and the soil beneath the leach field, although some refer to the leach field and underlying soil to be the soil absorption field.

The septic tank, a watertight container, separates the solids from the wastewater, allowing solids to settle to the bottom of the tank and the more floatable solids (oils & grease) to rise to the top. Nearly half the solids that remain in the tank decompose, while the rest build up in the bottom of the tank. This “sludge” at the bottom of the tank needs to be cleaned periodically in order for the septic system to continue to function properly.

The leach field, can consist of several different types of structures, all are where the wastewater is transported to the soil. The organisms, that live in the soil beneath the leachfield, then purify the wastewater before it gets absorbed into the ground below.

An additional filter is installed between the septic tank and the drainfield, removing even more solids and preventing the absorption field from becoming clogged, which would cause the septic system to fail prematurely.

Prior to beginning any septic system construction, Connecticut state law requires that the soil must be tested by the local health department to make certain it is suitable for a septic system. This evaluation ensures the soil is able to absorb and treat wastewater from the home.
