How A Septic Tank System Works


Septic Tanks:

A septic tank is a watertight chamber constructed of concrete or poly material. The average size is approximately 1000 to 2000 gallons. and have 1-2 compartments.  Tanks are buried underground unless they have a riser at ground level.

Water passes through the tank; the baffle holds the sludge to the front chamber and water filters to the leach lines.



Drain Fields:

The “leach lines” or “drywell” area uses the ability of stone and soil to filter and treat the remaining effluent/water. After water is filtered through, it uses evaporation to dry and continue.  G  & C Septic helps to treat solids that damage septic systems, including leach lines.  Majority of problems arise from harmful products contaminating the disposal field. They include: coffee grounds, cigarette butts, cat litter, baby wipes, egg shells, fats, grease, and oil.

Septic System Component Photos, Diagrams & Descriptions:

A concrete 24” diameter RISER is used to bring the opening of the septic tank (lid) to grade for easy access when servicing.

A SEWER LINE leaves the house foundation (sewer line) and connects to the septic tank. It will also leave the septic tank outlet baffle and connect to either a pump tank and/or distribution box and/or disposal field leach lines.



All the waste-water from the house enters the tank through the INLET BAFFLE. This baffle needs to be intact. THE OUTLET BAFFLE prevents the scum layer from escaping the tank, contaminating the leach lines.




Septic inspection
Many systems built after 1999 have a PUMP TANK. The pump tank comes after and is connected by a delivery line to the septic tank. A pump tank is needed to pump wastewater that flows out of the septic tank up to the top of a mounded disposal field or is used to control the amount of effluent being dosed over a disposal field.
