What is typically found in a pump tank/dosing chamber?

In a pump tank or dosing chamber, the primary purpose is to collect and store sewage that needs to be pumped out for disposal. This chamber acts as a holding area for wastewater that has undergone some initial treatment before it is pumped to a drain field or another treatment method. The pumping process helps to manage the flow of wastewater and ensure that it can be treated effectively at subsequent stages.

This design is crucial in areas where gravity alone cannot efficiently move wastewater to its final destination. While effluent that may be ready for further processing or filtering can be present in some systems, the primary focus is on ensuring that the sewage is properly contained until it is ready for disposal, making it essential that the pump tank or dosing chamber functions as it is intended.
