Well I cannot say I ever ran sewer lines professionally but I did go to college and studied environmental engineering. The national plumbing code specifies 1/4 to 3 inch drops per foot:
Balkin Plumbing
However North Carolina seems to specify a shallower slope: NC Code or the use of Mannings formula. That is a minimum 6 inch line tho.
Florida code goes into more detail: FL Code and uses the 1/4 inch per foot for 2.5 inch line. I went to school in Florida.
And he is right, you will get inspected for a water system frequently. They will at a minimum check chlorine levels and maybe once a year run more complete tests for fecal coliform bacteria and other items.
Let me point out that the intensity of oversight by the regulatory agencies varies from state to state. From paranoid (Florida) to eh in some other states. I have no idea where NC falls.
Jim,
I was not calling you out as Plumbers and Main Lines are totally different in the specifications used and the methods used, but the .5 percent is what is normally used across the country for 8" mains, we have laid larger mains at much less as water will run downhill even if the hill is almost flat.:) Just try to Imagine How Deep the lines would be if the Slope/fall has anything near 2 percent vs .5 or less? Plumbers use a level with A 1/4 bubble fall which usually works out to something around 2+ percent of fall, and that is fine for short runs with 4" pipe.
Can you imagine how deep the lines would need to be if the street was say a mile long, using the plumbers specs that you are referring to? Every foot deeper in the ground cost $$ lots of $$$$ so the sewer lines are usually designed to stay as shallow as possible so the developer and the repair crews, later do not go broke getting to the pipe.
Again not trying to be a PITA - as often Google sends you to the wrong page for information.
The next thing the owner would need to understand is the Advantages of an Aerobic Vs. Anaerobic Septic System - IMHO for a campsite he would be best served with an Aerobic system - while requiring an air pump it will likely need little other maintenance over the life of the Park.
One more thing to keep in mind is the way the systems are laid out - while trees may be the Campers friend they are in the way of the sewer and water and working around them will cost $$ lots of $$$$$$$, so the owner needs to keep that in Mind.
I could go on and on but........the biggest question for the OP is Budget and Mission - both are critical as none of this is cheap - if you do a lot of the work, yourself (possible but not likely) it still requires significant resources. (Ask IvyLog, as he has done this successfully and could contribute much to the OP)
Sorry for the long lecture, but his needs to be well thought out, as it is an expensive exercise, with a very LOW ROI.
