CHAPTER 3: PUMPING STATION 3.1 INTRODUCTION

Part B: Operation and Maintenance3 - 1 CHAPTER 3: PUMPING STATIONCHAPTER 3: PUMPING INTRODUCTIONP umping stations are either as in-line for lifting the sewage from a deeper sewer to a shallow sewer or for PUMPING to the STP or the out fall. They are required where low lying development areas cannot be drained by gravity to existing sewerage infrastructure, and/or where development areas are too far away from available sewerage infrastructure to be linked by gravity. The O&M of PUMPING systems presented here applies to all such types of PUMPING stations. TYPES AND STRUCTURE OF PUMPING STATIONSThe type of PUMPING stations can be (a) Horizontal pumps in dry pit, (b) Vertical pumps in dry pit, (c) Vertical pumps in suction well and (d) Submersible pumps in suction sump.

B. Centrifugal pumps if installed with negative suction should be primed before starting. C. Pumps should be operated only within the recommended range of the head-discharge characteristics of the pump. • If pump is operated at a point away from duty point, the pump efficiency normally reduces.
