Usually I'll draw up the house plans, send those off to the structural engineer and also send them to the septic engineer. The engineers send any revisions back and those are incorporated into the plan set. The septic location is then noted on the plot plan for the house. Other than the location shown on the plot plan, nothing more for the septic is noted on the plan set for the house. The septic design is usually a separate .PDF which is submitted via EPIC to the County & Department of Health (state dept) along with the .PDF of the stamped house plans. (as well as a few other .PDFs such as Owner Declaration & Project Declaration and any other required documents) This is just the current method that we use, it can be different for other folks and other times.
As for the septic installation, will a truck be able to get to the area behind the house once the foundations are in? The septic folks here had a Takeuchi 135 excavator (Dave's Land Services) which is narrower than a car and didn't require any rock/soil/fill added to the project, but this is Hamakua and not Puna so there may be different requirements in Puna.
