10.2 Pump station with pump control function
The waste water from households and industry, together with surface
water, is fed to the sewage treatment plant via an extensive network
of sewers. If the natural gradient is not sufficient, various pumping
stations are required to compensate for the differences in height. The
level measurement in the inlet shaft serves for the economic control
of the pumps. The intelligent control of several pumps can be easily
adjusted by the controller.
