Advice on burying sump pump discharge pipe

I plan to bury my sump pump discharge pipe from my house to a storm drain type thing in the rear of my backyard. One of my neighbors has there sump pump running there too. The distance is about 40 ft roughly. I live in Midwest. There is already a decent slope from my house to the drain. I plan on using PVC schedule 40 4 inch pipe the entire 40 feet. The pipe will be sloped a good amount. I'll install a freeze guard at source of discharge. How deep should I bury? Is below freeze line really necessary if I have a big slope. Do I need to lay a gravel at bottom of trench before placing pipe in? Or does that not matter? Any thing else you would recommend? Should I use something other than pvc schedule 40? Anything else I should think of? This is a sketch of my idea. Thanks for any input. https://imgur.com/a/iYHWw9m submitted by /u/Dependent-Capital463 [link] [comments]
