ABOVE GROUND, MULTI-OUTLET PIPELINE
A water distribution tubing consisting of
aluminum, PVC or lay-flat polyethylene pipeline
with closely spaced orifices or gates.
• To increase water use efficiency on irrigated
• To reduce irrigation-induced soil erosion.
• To reduce excessive runoff, flooding or
ponding associated with inefficient irrigation
• To improve the productivity, health and
vigor of the crop.
• To increase the quantity and quality of feed
and forage for domestic animals.
CONDITIONS WHERE PRACTICE
The practice applies to irrigable land suited to
surface application methods. This practice shall
not be used in lieu of buried pipelines for
conveyance systems. However, reaches of un-
gated pipe may be used
to obtain necessary working pressure for the

less than 300 feet),
to convey water to various points within a
for splitting irrigation runs as in surge
• where rock precludes the installation of
Water supplies and rates of irrigation delivery
for the area served by the multi-outlet pipeline
shall be sufficient to make irrigation practical for
the crop to be grown and for the method of
General Criteria Applicable To All Purposes
Pipe Sizes. For durability and transportability,
rigid pipes shall be a minimum of 6 inches in
diameter and not greater than 12 inches in
Working pressure. The maximum working
pressure for rigid pipe shall be 10 pounds per
square inch or 23 feet of head. Excess working
