Farm/shed water pump (A3)

Chlorinated water is delivered to the sheds by a hydro-pneumatic water pump (figure 6). Often, two or three variable speed pumps are used in series to allow efficiency of power use, back-up contingencies and extending pump life.

To limit biofilm build-up, it is advisable from time to time to flush the farm water reticulation system at various discharge points around the farm (taps and hydrants). For significant biofilm build-up it is advisable to use a higher concentration flush with an oxidizing sanitiser during batch turnarounds. The effectiveness of chlorine is limited by biofilms, and chlorine does not remove existing biofilms.
