What is the minimum size of a pump tank compared to a septic tank?

The minimum size of a pump tank should be equal to or greater than the size of the septic tank to ensure proper functioning and minimize the risk of overflows or system failures. The pump tank plays a crucial role in transporting effluent to the next stage of treatment, and if it is not sufficiently sized, it may not hold enough wastewater to accommodate peak flows or allow for adequate retention time. This can lead to potential malfunctions or back-ups in the system, which can compromise its effectiveness and lead to costly repairs. Additionally, an appropriately sized pump tank allows for adequate pump cycling and helps maintain a balanced operation, ensuring that the system can manage variations in wastewater flow effectively.
