    How do they bury water lines up there without it eventually popping up out of the ground or freezing up ?

    Water lines (and all other utilities) are buried well below the frost/turf line (depending on area), this is anywhere from 4 to 8 ft in depth at the shallowest point. The earth shifting and "humping" during thaw is limited to the turf affected by the frost line, which is most usually limited to the top 4 ft. or so.

    I believe the utilities are all buried in a universal trench both in easement and to the property, with what is called hazing between each type of utility (I've seen this in Az. as well). So the trench may be 15-20 ft. in depth with sewer, a layer of soil, then water, layer of soil, gas, layer, electric, layer, and so on...

    I can't guarantee this information is correct, but I believe that's what my Uncle (who has been in the oil industry AND construction up there for 25 years or so) described to me.

    As far as marking is concerned, if the utilities are placed as stated, then theoretically only one facility would need flagging with a standard easement rule on either side of the flag applying. Common sense would state each city has a "blue flagger" position responsible for marking the easement or possibly the communication facilities would do the marking since they are most likely placed the shallowest respectively.

    I can't imagine they have much need for anything but either a city based "blue flagger" (which would most likely be a secondary duty) to mark the easement or possibly in-house locators (again secondary for line techs)for the communication...especially since the dig season would be less than 2-3 months in most areas, as the ground is like iron the rest of the time.

    Again, this is based on a conversation I had with my Uncle like 8 years ago...think I may research it and verify...interesting...
