I am wondering if anyone out there knows, generally, what the depth of the frost line is in the Edmonton area.

I am assuming that I can bury a raw water pipeline 8 feet below ground, and the water in the line will not freeze.

I suspect frost penetration varies widely dependent on many factors (while I don't know about the accuracy or dependability of same for design purposes, you may want to look e.g. at Figure 1 at the site http://irc.nrc-cnrc.gc.ca/pubs/cbd/cbd026_e.html and e.g. also say th einformation including a freeze index map like on pg 11 of site  http://www.owenscorning.com/worldwide/admin/tempupload/pdf.3-74495-199_HighDensity_E.pdf).  
Hopefully you will get perhaps better experience-type response from area.

In a similar thread some time back, someone suggested asking local undertakers. They'll know.

The publication at http://www.agr.gc.ca/pfra/pub/pipelinealta_e.pdf gives a suggested burial depth and has a frost depth map for Alberta. (Googled it)
