Why dangerous? Often they use a yellow or white plastic pipe/conduit which is of a thinner material than the water pipes. The absence of elbows, tees, reducers, unions, couplings. junction boxes etc and glue seems to be the issue... the wires coming out and being joined in the open like that, where water can get to it is terrible work. Of course there being no grounding/earth or fault protection allows a pole to become live. In this instance the problem happened near a metal fence and power pole..... There was an example on 2nd Rd one time that was simply a puddle of water, .One need not look far to see plenty examples like this around town.
