What is the primary function of a dosing tank in a septic system?

1. To store solid waste

2. To pump effluent to drain fields

3. To treat wastewater

4. To infiltrate stormwater

The correct answer is: To pump effluent to drain fields

The primary function of a dosing tank in a septic system is to pump effluent to drain fields. In a typical septic system, wastewater flows from the home into the septic tank, where solids settle at the bottom, and liquid effluent is separated. The dosing tank collects this liquid effluent before it is distributed to the drain field. The dosing tank is equipped with a pump that is activated when a certain level of effluent is reached. This ensures that the effluent can be evenly and appropriately distributed in doses to the drain field, allowing for adequate treatment and preventing over-saturation of any particular area. This process is crucial because it helps maintain the efficiency of the drain field and prevents clogging or backup in the system. In contrast, a dosing tank does not serve to store solid waste, treat wastewater in the same manner as a septic tank, or infiltrate stormwater, which are functions associated with other components or separate systems.
