Colored piping in water treatment plants.
Colored piping in water treatment plants.
(OP)
I am looking for a listing of what color certain pipes should be colored in a treatment plant. I was told raw water pipes are red but have not found that stated anywhere. Any help would be greatly appreciated.

usabluebook has a copy of the ten states standards in their catalog, link below

but check your state, I know some states require marking in accordance with ASME boiler code which have labels according to hazard level: white on green, no hazard; black on yellow, hazard; white on red, fire system.
