Question: 1 / 400

How much reserve capacity must dosing tanks using pumps have?

One week’s flow

Two days’ flow

One day's flow

The requirement for reserve capacity in dosing tanks using pumps is set to ensure that there is enough stored wastewater to maintain system function during times when the pump is not operating, such as during maintenance or power outages. Having a reserve capacity of one day's flow allows for a sufficient buffer, ensuring that the system can handle variations in flow and any potential malfunctions without causing backups or overflow.

A reserve of one day's flow is generally viewed as adequate to accommodate typical fluctuations in the system's usage while providing time for service interventions, irregular peak flows, or emergencies without disrupting the overall function of the septic system. This helps maintain environmental safety and regulatory compliance.
