How Does my Septic System Work?
Septic System Components:
A typical septic system has four main components: a pipe from the home, a septic tank, a drain-field, and the soil. Some homes have a clean-out pipe connected to the main pipe from the home. Microbes in the soil digest or remove most contaminants from wastewater before it eventually reaches groundwater.
Pipe From the Home:
All your household wastewater exits your home through a pipe to the septic tank.
Clean-Out Pipe:
Clean-out pipes are typically 4" in diameter made of black ABS pipe or white PVC pipe and have a cap screw into the top made of similar material. These caps screw into the clean-out pipe and have a protruding square nub. Sometimes backflow into the home can be remedied by removing foreign material build-up from your clean-out pipe. This is not a point of access for pumping your tank, however. It serves as an access point to insert electronic equipment when attempting to locate your tank.
Septic Tank:
The septic tank is a buried, watertight container typically made of concrete, fiberglass, or polyethylene. It holds the wastewater long enough to allow solids to settle (forming sludge), and oil and grease to float to the surface (as scum). The septic tank also allows partial decomposition of solid materials. Compartments and a T-shaped outlet in the septic tank prevent the sludge and scum from leaving the tank and traveling into the drain-field. Effluent Filters are recommended to keep solids from entering the drain-field. Newer tanks might have risers with lids at the ground surface to allow easy location, inspection, and pumping of the tank. Drain-Field: The wastewater exits the septic tank and is discharged into the drain-field (soil treatment area) for treatment by the soil. Every time new wastewater enters the tank, partially treated wastewater is pushed out into the drain-field. If the drain-field is overloaded with too much liquid, it will flood causing sewage to rise to the ground surface or create backups in plumbing fixtures. A reserve drain-field is an area on your property suitable for a new drain-field system if your current drain-field fails. Treat this area with the same care as your existing drain-field.
Soil:
Septic tank wastewater flows to the drain-field, where it percolates into the soil providing final treatment by removing harmful bacteria, viruses, and nutrients. Suitable drain-field soil is necessary for successful wastewater treatment.
What Does Proper Maintenance Include?
A properly maintained Septic System should be serviced every three to five years. Septic System Services include removing the contents of both the liquid and solid side of your tank. We suggest the addition of an inspection to visually inspect the tank, to ensure the inlet & outlet baffles are in place and performing a 30-minute water test to make sure that the leach field is in proper working.
Where Is My Septic Tank?
Unsure of where your septic tank is located? The first step is to contact your city or county's Building Permit Department and request the map supplied by the installation company. In some areas, the EPA or Health and Human Services departments keep septic system information. Should no documentation be found, or you would like to confirm that the records on hand are accurate, Bonanza Septic & Jetting Solutions has the equipment to map and confirm current available maps.
