for pressure dosing systems shall consist of two or more distribution laterals
connected to a central or end manifold. The following requirements shall be
1. The size of laterals shall be no less
than one but no greater than three inches in diameter and shall be chosen in
size of the manifold pipe shall be chosen in conformance with

conform with the requirements of
3. All joints and connections shall be

4. Holes shall be spaced evenly, in a
straight line along the invert of each lateral. Hole diameter and spacing may
vary from one-quarter to one-half inch and from 30 to 60 inches, respectively,
and shall be chosen in conformance with
bed systems, holes in adjacent laterals shall be off-set by one-half the hole
spacing so that the distance between holes in adjacent laterals is maximized.
All holes shall be deburred.
ends of the laterals shall be capped. A small hole shall be drilled
horizontally in the end-cap of each lateral, near the crown, to facilitate
venting at the beginning of each dosing cycle.
6. Each individual distribution line shall be
approximately level. In no case shall the slope of the distribution lines be
greater than two inches per 100 feet.
7. An inspection port shall be provided in
