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.
