The septic system is a natural method of treatment and disposal of household wastes for homeowners who live in an area where there is no municipal sewage disposal system.
Although individual designs vary, a typical gravity fed system is composed of three parts:
1. septic tank -- 2. distribution box -- 3. drain field or leach field
Wastewater and solids exit the home and end up in the septic tank where solid are broken down by naturally occurring bacteria that inhabit the tank. A typical septic system drain field consists of trenches filled with gravel and a perforated pipe. The beneficial bacteria filters the effluent before it is returned to the water table. The treated water is full of nutrients and enriches the earth. It benefits plant growth and helps in maintaining healthy composition and structure of the soil. |
