what lengh of (65 mm diameter) copper pipe will be requiered to contain each of the sand gravel and water?
Just remember that all construction, electrical, plumbing etc, must be inspected and pass the local building code. In running all the piping through the walls, you are perfectly safe, but you should be prepared for emergencies with the appropriate cut-offs.
Besides the other suggestions, take a picture with a tape measure or yard stick along side the pipe for future reference. Same for anything buried in the wall. Good luck.
You need to apply Metal Nail plates on the bottom and top (2), 2x4 plates of the wall so nails or screws from the drywall or trim nails do not puncture the pipes in the wall. Other then that, you are fine.

10 millimeters long, if none of the gravel has a small dimension over one centimeter. I think you forgot to tell us something such as why you want sand gravel and water in a copper pipe? Neil
