Control system for waste water pumping station
A control system for a waste water pumping station (3 figure 1) in a waste water network has a well 6 for containing waste water entering through an inlet 7, a sensor 11 for measuring the level of the well contents, at least two variable speed pumps 8 for pumping waste water out of the well through an outlet 9 and a control panel (10 figure 2). The control panel operates the pumps to maintain the level of the well contents between a normal start level 20 and a normal stop level 21. The control panel (10 figure 2) operates the pumps 8 periodically in an optimisation test mode to determine the most energy-efficient speed for each pump 8, then operates each pump 8 at that speed in normal conditions until the next time the control panel (10 figure 2) operates the optimisation test mode.
