When a secondary water supply system is exposed to the public water system, all secondary water piping shall be identified by distinguishing color or tags and so maintained that each pipe may be traced readily in its entirety. All process water piping shall also be color coded or tagged. If piping is installed so that it is impossible to trace in its entirety, it shall be necessary to protect the public water supply at the service connection in a manner acceptable to the Superintendent of the Department of Water and Sewer.
