If your home runs on a septic system, wastewater from the house travels through the main sewer line into the septic tank. In the tank, bacteria digest organic matter and separate solid waste from the water. After that, the wastewater leaves the septic tank and is discharged to a drain field or leach field where pollutants in the wastewater are removed. The wastewater is then distributed through some perforated pipes for treatment.
- If you reside in a remote part of Australia or have a holiday home in a location that is not connected to the municipal council's sewerage system, it is highly likely that you have a septic tank installed on the property. These receptacles offer a convenient way to eliminate wastewater and are typically designed to be used for a long time. However, just as other household items, septic systems do have a shelf life, and it is prudent to know when to replace your tank before you have a septic disaster on the property.
