About Intermediate Pumping Station / Sewage Pumping Station
Working Principle
Pumping stations are critical infrastructure components in sewerage systems, designed to transport used water from lower to higher elevations where gravity flow is not feasible. They serve as intermediate hubs to maintain the flow of sewage through the network, particularly in low-lying areas or across varying topographies.
Purpose and Application
Overcome elevation differences in the sewer network.
Maintain consistent flow towards the Sewage Treatment Plant (STP).
Prevent backflow and reduce the risk of sewer overflows during peak flows.
