As you have seen from the videos presented, especially the one from Washington on using pressurized systems, the results are reduced impact on receiving ground waters due to the unsaturated flow under the drainfield. You may wish to watch the video again. There have been proposals that no matter how good the soils is and the fact that a standard septic tank and drainfield can be installed that in all cases a low dose pressurized system must be used.

If you were the environmental health person implementing such a requirement, knowing that it doubles and even triples the cost of a system, how would you go about justifying this to a permit applicant?
