NarrativeAR No. #Low Pressure Irrigation
Recommendation
Install a variable speed drive (VSD) on the 40 hp river
submersible pump. This will allow the system to operate at a lower
pressure, delivering the same water with less energy than the
current method and reduce total pump operating cost by 35.5%.

1 MMBtu = 1,000,000 Btu, 1 kWh = 3,413 BtuBackgroundCurrently the 6
tower Reinke pivot utilizes low pressure drop down nozzles to
deliver water to the field yet the pump runs at relatively high
pressures. This is not an efficient method to deliver water to a
field. Variable speed drives (VSD), are able to change how a pump
operates based on an adjustable parameter such as pressure,
resulting in significant energy and demand savings.
The VSD will also soft start the motor by slowly ramping it up
to full speed instead of doing it instantaneously. Variable speed
drives and low pressure irrigation have many benefits besides
reduced energy costs:
Reduced Maintenance Costs - A soft start will also reduce motor
wear and damage caused by hard starting as well as maintenance
costs associated with water hammer, sprinkler head damage, and
flexible coupling damage extending the expected life of the
system.
Increased Yields - Low pressure drop down nozzles result in a
more uniform distribution of water on the field. This reduces under
or over irrigated sections, increasing yields.
Water Conservation - Low pressure drop down nozzles reduce wind
drift and evaporation losses usually associated with conventional
methods of irrigation. This increases the amount of water delivered
to the fields, reducing irrigation times.
Motor Protection - VSD's help reduce the effects of voltage
swings in the power distribution system due to other systems
kicking on or off. VSD's can maintain full output voltage at full
load, with voltage sags as low as 15 percent helping to protect the
motor.
Proposal
We recommend installing a Variable Speed Drive controlled by a
pressure sensor on the 40 hp submersible river pump motor. This
will allow system operation at a lower pressure while maintaining
the current flow rate. The VSD will also allow soft starting of the
pump resulting in reduced lower maintenance costs (not included in
our estimates). If the previously mentioned actions are taken, they
will save 8,810 kWh annually and result in an annual cost savings
of $614. Take advantage of the included incentive programs for a
net payback of 9.8 years with an implementation cost of $6,020.

Notes
Based on annual pump electrical draw, delivered flow, and a
calculated average pump head; the pump is delivering needed water
at a 56.3% average system efficiency. According to the Hydraulics
Institute Standard ANSI/HI-1.3, the modeled average flow and head
delivered to the irrigation system can be developed up to an
optimum efficiency of 72.5%. This low efficiency could be caused by
the pump operating off of its Best Efficiency Point (BEP) or by
pump degradation. We recommend having a pump specialist inspect the
pump to determine if repair or replacement is needed. Doing so
could reduce associated energy consumption by 5,540 kWh resulting
in an additional $386 annual cost savings. These savings are not
included in this recommendation.
VSD savings associated with varying end gun use are not included
in this calculation, which could yield increased savings.
The end gun nozzle size may have to be replaced from the current
0.65" to a 0.75" diameter in order to provide the desired flow and
range. This cost is negligible and therefore not included in the
calculation.
Our analysis assumes pump efficiency will not change
significantly when its operation moves to a new point on its
performance curve with VSD control and reduced system pressure.
An alternative solution is to install a pump specifically
designed to operate at the current flow conditions. This would be
beneficial as both savings mentioned above would be obtained for a
total annual savings of $1,000 and 14,350 kWh, however, we did not
recommend this because the lack of adjustability and fine tuning
available if the system end use ever changes. This system would
however not be as able to adjust to varying end uses such as
elevation change or end gun operation.
