TM 5-814-3/AFM 88-11, Volume III
(11) When the system is fully laid out with pipes cemented in place, it should be tested and dosing
volume adjusted as necessary to assure that all holes are operating, that all pipes are full at each dosing, and
that there is no excess pressure. Pressure head at end of laterals should be about 2 ft when in full operation
at time of pump cutoff. Pipes are then covered with more gravel, then protected by woven plastic fabric
covered by straw. Finally, subsoil and then topsoil are carefully spread over the top, and the shaped mound
is seeded to grass. Do not neglect to ditch the edges of the mound to channel runoff around the mound.
