Pumping - Overview The amount of energy used for water pumping
depends mainly on the farm's configuration. For example, the
pump's requirements will be different if the water comes from a
bore, a deep well or from a stream. The position of the water
storage also has its importance; if they are placed above the
level of the shed gravity can often be used instead of pumps.
However, the following recommendations always apply when
choosing pumps: - Use energy efficient pumps and motors. - Match
pump size to the usage. - Consider the best way to control pump
i.e. time clocks, Variable Speed Drive. Note that a pump
throttled will use more energy than the same pump running at
lower speed or a smaller pump to achieve the same result. The
simplest way to reduce the energy usage from effluent pumping is
to reduce the volume of effluent on the yard. The following are
some recommendations on how to reduce the volume of effluent: -
Make sure that guttering and downpipes divert storm water off
the yard. - Install storm wat
