What is a Facility Planning report ?
Facility planning reports are studies required by counties for plat approval of new lots. They must be prepared by a civil engineer or Registered Sanitarian (RS).
What conditions are needed to install a standard drainfield septic system ?
Four feet of soil with no rock layers.
Do I have to have an aerobic treatment system (spray) if there’s less than four feet of soil on my property?
No. There are other types of systems, e.g. low-pressure dose and mounds that can be used instead. They tend to cost more to install than aerobic systems.
