Water in these lines are generally slow moving and as such ice crystals could form in the water which would not only begin to slow the flow even more but begin to grow and expand causing the pipe become blocked or puncture. So are buried below a depth not normally affected by winter temperatures.
How do you find underground water pipes?

How deep does PEX have to be buried?
PEX pipes and all underground piping should be buried at least 12” to 18” below the frost line to protect the pipes from freezing. The frost line refers to the furthest depth underground groundwater begins to freeze, also called the frost depth. In colder zones, the frost line can be three to four feet down.
How many inches or feet above foundation is the water line?
All too often I see ponds in between these sidewalks and the house because the sidewalk acts as a dam and doesn’t allow surface water to drain away. The best way to prevent all these issues is to keep the top of the foundation at least 18 inches above grade. You can even go up as much as 24 inches.

How Cold Does it Have to be for Pipes to Freeze? It must be below freezing inside the plumbing long enough for an ice dam to form. Pipes vulnerable to freezing at this temperature are usually located in an unconditioned attic, basement, crawlspace, or along an exterior wall. Underground pipes can also freeze.
Is it OK to use PEX underground?
Some plumbing contractors may be surprised to know that PEX is approved for use in underground as well as in-slab applications. Installing PEX pipe in the slab or underground can help reduce costs because there are no hangers required and less ladder time for installers (adding to installation efficiencies).

What kind of pipe do you use for buried water lines?
Cross-linked polyethylene, or PEX, is a plastic water supply line suitable for both buried and above ground applications. Like a thick, strong hose, PEX is a flexible tubing material capable of stretching around bends and turns without pipe fittings. PEX withstands chemical damage, high temperature and high pressure.
What kind of water pipe can be buried?
High-Density Polyethylene (HDPE, often just “PE”) has become one of the most popular choices for underground service lines, thanks to its corrosion-resistance, durability, and competitive price. Some codes require that buried plastic lines under 2″ in diameter be PE (rather than PVC).
