Saw a pic of exactly that just recently, think it was in the heavy equipment forums on Lawn site, will have a look and see if I can find it for you...
CRAFT Senior Member
"NOT" A Good idea at all !!! ointhead ..... Its not the crushing of the pipes you should worry about, it's the compaction of the soil that makes it a BIG NO-NO ..... when you compact the soils it totally makes the soil impermiable ...... even if you were able to use alot of aggregate ....

In the eighty"s several local contractors used CEMENT chambers under the paved driveways . The theory at the time was - by the time the system failed the driveway would be cracked and it would be time to replace it and that would be cheaper than landscaping .
Randy88 Senior Member
Talk to the state sanitarians and find out what systems are allowed in your state and also your area, there are a lot of types of systems allowed and you can even go with a pumping system, just pump it out say once a month or so instead of having a drainage field at all, weigh the cost of pumping vs.

These drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide. The individual drain lines will usually be 8½ to 10 feet apart (see Figure 2). It is important to note here that each drain field system will vary from the next. It is important that the homeowner have a detailed layout of their system (giving the locations and dimensions of individual components) for their reference.

What are the most common trees that are damaging drain fields?
Trees with very aggressive root systems that should be avoided include willows, red and silver maples , beeches, birches, elms and poplars. Some trees with less aggressive root systems include cherries, crabapples, dogwoods, hemlock and oaks. To reduce the associated financial risk and emotional stress of a failed system, plant trees at least as far away as their estimated root spread at maturity. There are two methods used to estimate tree root spread. One rule of thumb is that roots extend out from the tree two to four times the diameter of the canopy. Another is that tree roots spread out one to three times the height of the tree. These estimates should be considered a bare minimum, and to reduce the risk, the trees should be planted even further away from the drain field.
