As a rule of thumb, the spacing of pipe supports for steel pipes in liquid service, expressed in feet, may be taken as the nominal pipe size, expressed in inches, plus ten. For example, the spacing of pipe supports on a 6 line will be approximately 6 + 10 = 16 feet. This spacing changes at high temperatures and for materials other than steel. For example, for copper tubing, support spacing varies from 8-ft for 1 tubing to 12-ft for 4.
1 Septic drainfield trench spacing: The trenches are dug about 6 feet apart on center (center of pipe to center of next pipe) which allows, in good design, space for a set of replacement trenches to be placed between the original ones when the first set fails. Septic drainfield gravel specification: typically, washed gravel, 3/4 to 2 1/2 (pretty big) gravel is placed for a depth of 12 under the drain line piping (septic drain tile in some references).
