water pipe running inside electrical room

[chivodelacampana]

What kind of mechanical protection can I provide to a 12" sanitary line that has to run on the roof of a 2000 KW emergency generator room (against one of the walls) as well as on the roof of a 2500 KVA pad mounted transformer room, 13.8 KV @ 480Y/277 (also against one wall). Both located on the second basement of a new construction. Property line and storm channels outside oblige me to consider this solution.We have explored many ways but unfortunatelly this is the only one acceptable to the project. We have read the code and no way but is there an exception around?

See 90.4 for help.

this does not sound like an electrical problem to me. seems like the architect needs to get involved.

IMO if the water or sewer line was encased in 2" of concrete it would be considered outside of the building. We do the same with a service by running it under a building slab. If you used polyethelyne pipe it would last forever.

Tom, I don't think water or sewer pipes are covered in Article 230. Water and Sewer have their own codes and 230.6 doesn't fit.

The NEC can and does demand that the area be kept open for electrical use. I don't see how this will keep the area open, it will just cause more congestion.

how about lowering the ceiling so the sewer pipe is no longer in the room?
