I don't know your profession but let's take a statistical guess and say you're a software developer.
If I asked you to drive out to my place to take a look at 500 lines of Javascript, and tell me if the code is kosher, and if you're wrong I'm going to sue you. How much would you want to be paid to do that?
I think the local municipality typically sends an employee out to do the inspection? At least that's how it worked for me in the past (tbf that wasn't specifically sewer though). Permits having a nominal paperwork fee is understandable.
I very much doubt that the inspector only visits one property per day, or that they are paid anywhere near $1000 per day.
