VSD
Lifting Feed in pumps Redundant centrifugal pumps: Flow is controlled
by changing the speed of rotation in order to
better manage water ow variation.

redun-
dant
Rain water
pumps
Centrifugal pumps: Flow is controlled easily by
valves on the pump discharge manifolds. The
rain water tank allows easy management of ow
variation.
