What does the National Plumbing Code require for installing a main potable water supply line for a home?

I am installing an underground water line to provide water to lawn hydrants in a few places on my farm with plans to connect the end to a home in the future. I have some unusual considerations. My street pressure is 200-250psi and I am running the pipe roughly 1000 feet. It also gains about 100feet in elevation. I plan to run the full street pressure in the line and use individual pressure reducers at each hydrant along the run. Any helpful advice appreciated!

Please don t tell me to hire a plumber. That would not be helpful because I am not going to do that.
