Why is it important to have a spare pump installed near an active one?

Having a spare pump installed near an active one is crucial to ensure smooth operations during maintenance. This setup allows for one pump to remain operational while the other is taken offline for repair or routine servicing. Without a spare pump, any necessary maintenance could lead to interruptions in sewage treatment processes, potentially compromising the system's efficiency and safety. Continuous operation is vital in sewage treatment to handle inflow and maintain adequate treatment levels, and having a backup pump readily available ensures that there are no delays or disruptions in service.

While maintaining continual pressure, reducing noise levels, and lowering energy consumption are important considerations in pump operations, they do not address the operational reliability aspect that a spare pump provides during maintenance activities. Thus, the focus on ensuring uninterrupted service during such times makes the presence of a spare pump essential.
