The primary goal of a cleaning process in wastewater systems is to remove and transport septage to a disposal location. This step is critical in maintaining the functionality and efficiency of onsite wastewater treatment systems. Over time, solids accumulate in the septic system, which can lead to reduced treatment effectiveness and potential system failures if not addressed. Regular cleaning ensures that these solids, or septage, are efficiently removed from the system before they can cause any environmental or health hazards.

While other options may be part of different aspects of wastewater management, the cleaning process specifically focuses on the physical removal of waste. Testing for efficiency, inspecting for upgrades, or evaluating performance can be important practices, but they do not directly address the immediate need for cleaning and maintaining the system's operation. Thus, the answer highlights the essential function of managing waste to ensure the ongoing efficacy and safety of wastewater systems.
