good mini spray & drip
irrigation system needs two things: a good
filter and a good pressure regulator. The filter stops the
emitters and mini spray heads from getting clogged up. The
reason for the pressure regulator is to keep high pressure
from blowing apart the emitters and
mini spray heads. There are
certain water pressure limits that they can operate at.
When I took over the project, the water pressure was 150 psi.
It would blow the emitters to pieces. One week later
because we had a lot of rock on the hillside and the 2
inch pipe was exposed to the sun light for 15yrs. Four
feet of 2inch pipe went everywhere. It was fortunate
that no
customers were around. I put in brand new Pressure
Regulators. The pressure is now 30psi. I had no problems
once I squared it away.
The advantages of
drip Irrigation System is low
application rates and low flow
rates. However, the fly in the ointment is
sometimes the high cost of the drip irrigation parts
themselves: emitters, flush valves and air relief valves.
Next is
better uniformity. All the plants get the same amount of
water meaning no over irrigation if designed properly.
Also, drip irrigation will
improve controlled root zone environment and improved disease
control. Drip Irrigation overcomes difficult soil and
terrain problems if designed properly. More efficient:
Chemical Application, and last but not the least is
Water Conservation.
Drip has its roots in Agricultural irrigation, where in
many parts of the world it was the only option for harsh
climates with limited water supplies. Once again we are
starting to have population problems. We are over populating
the planet for the constant limited water supply we have.
We must conserve and not be so wasteful. This is why drip
irrigation and mini sprinklers are a good option. |
