I'm looking at a new location for a house, and all utilities will need to cross a creek at some point - it's about 10 feet wide, 3 feet deep at the lowest spot. Due to the proximity of it to the road, I do not think boring under the creek would be very easy, and you can't run over it unless you use heat tape - but there is no electric near the creek.
My current thought is to just dig a trench across the ditch about 1 foot deeper than the bottom of the ditch (so 4 feet down), and then run the water line across there with concrete around the line, then filling it back in with dirt. Since this is well below the frost line, and the creek never completely freezes, it should be fine in the freeze/thaw cycles. I do realize, however, that I would need to get the appropriate permits before digging a trench through the ditch.
Does anyone have any additional suggestions or advice for this process?
