Hello,

I plan to source water from a nearby stream for irrigation. This
stream is roughly 200' from the first location of a drip irrigation
supply line. The next supply line is an additional 200' away. I plan to
use valves and splitters to choose which area I will be irrigating, but I
plan on only irrigating one zone at a time. The largest zone is roughly
3,600bedft, likely split up into 100' rows or so,..so picture 36 100'
rows for this area. Judging by an estimation for elevation from bottom
of stream to the high point in the field, I will require a pump which
can push between 20 - 30 ft of head. The drip tape operates at 10psi,
but I've heard it could also operate up to 30psi. I plan to use a
quality pressure regulator with a gauge to control pressure supply to
the drip system. I am a little worried about creating too much back
pressure on the pump. The lines from the pump to the drip supply line
will be regular garden hose. The drip's supply line is 3/4" polyethylene
tubing. The drip tape connects to the drip supply line. I plan to use a
generator to power the pump, probably 3,000 - 4,000 watts. My question
is, which pump do I buy? Though lots of research, I am still uncertain
about the type of pump I should be looking at! Either, centrifugal
(maybe too much flow), utility pump (perhaps not powerful enough), or a
multistage submersible pump??? Thanks in advance for any input.
