Kris, I don't know a Code-compliant solution, having not faced this. But I'll suggest that you not attempt to glue and seal conduit to keep the conductors dry, as it won't work permanently. Use wet-rated wire, expecting any conduit to provide only physical protection. THWN is wet-rated - that's the W. You might consider submersible pump cable also. Allan

The lakes here are flood control and fluctuate a lot, like 50 feet in a given year. The marinas are dragging the feeder wires all over the place on rocky bottoms. We kill very few people with this insane practice but as the feeder wires age I believe the fatalities will increase. This is ground referenced service in fresh water with poor conducting capability in the water. Very dangerous yet allowed. Your situation would be quite safe IMHO as there would be no stressing of the delivery system.

The pond is about 4 feet deep. How would you wrenches make this run? in weighted conduit with primer and glued joints? use boring and go under? out of conduit with wire directly in the water? Does code have anything to say about this specifically?
