Colored piping in water treatment plants.

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.

RE: Colored piping in water treatment plants.

I believe the American Public Works Association (APWA) is also an entity that publishes a "Uniform Color Code" that is sometimes used to temporarily etc. mark at least some underground utility lines (you could see much about this in a web search, e.g. colorful depiction at http://www.pp.okstate.edu/ehs/KOPYKIT/APWA%20Uniform%20Color%20Codes.PDF).

RE: Colored piping in water treatment plants.

Where are you located? the pipe colors are sometimes regulated by local laws. The answers above probably are related to USA.
