What kind of testing is done on a septic system after installation?

Operational testing to verify proper function is crucial following the installation of a septic system, as it ensures that the system is working as designed and is effectively treating sewage. This type of testing involves checking various components of the system, such as pumps, alarms, and the overall flow through the system. It helps to identify any immediate issues that could lead to system failures or environmental contamination if left unaddressed.

While structural inspections can certainly be conducted to assess the physical integrity of the septic system, they do not provide information about how well the system operates under actual conditions. Soil permeability testing is typically performed before installation to assess the suitability of the soil for a septic system but is not a post-installation activity. Random spot checks by local authorities may occur, but they are not a systematic testing method specifically designed to evaluate the operation of a newly installed septic system. Therefore, operational testing is the most relevant and critical step after installation to ensure the system functions properly.
