In a duplex sewage ejector system, each pump is sized to meet what condition?

In a duplex sewage ejector system, each pump is sized to meet peak inflow conditions. This is essential because the primary function of the pump is to handle the maximum anticipated sewage flow that the system might experience during its operation. By sizing the pumps to accommodate peak inflow, the system ensures that it can effectively manage sudden increases in sewage volume, such as during heavy usage or after rainfall, without risking overflow or system failure.

This approach also helps maintain proper sanitation and system efficiency, preventing any potential backups that could lead to damage or health hazards. Furthermore, in a duplex system, having each pump capable of handling peak flows allows for redundancy—if one pump fails or requires maintenance, the other pump can still accommodate the peak inflow levels on its own.
