In the past we have run PVC or rubberized outdoor SJOOW cord up water towers to get power to the catwalk or our box up top. This city wants it in metal conduit and clamped to the ladder standoffs inside the tank. This is a weird tank. Been doing this for 14 years and it is the first time I have had to climb 200' inside climb then climb down the outside of the tank to get to the catwalk. Plus the inside transition from the initial 170' to the last 30 or so is a very tight and very hard to maneuver transition. So bending conduit to fit all this is not my thing. They say they power wash and sand blast inside and want our power protected. OK.. So my question is would a flexible MX type conduit do the trick? Does it need to be jacketed or just protect from the blasting directly? I dont see any reason to go to full conduit. It would be hard to get it up the tower, in the tower, and bent to accommodate the tower design. I'm thinking doing PVC for the strait drops and over the side of the tank to the catwalk and at the difficult bends and weird junctions we will have to adapt to liquidtight.
