Supply System Color and Marking Information. All mechanical equipment, including control valves, appurtenant to recycled water supply systems shall be painted purple or composed of purple material matching Pantone color No. 512, 522C or equivalent. Recy- cled water supply systems shall be identified and permanently marked with clearly visible black uppercase lettering on pur- ple background. The identification may be accomplished by labeling metallic and non-metallic piping using purple-col- ored (Pantone color No. 512) adhesive Mylar PVC tape affixed along the entire length of the pipe, or using non-metal- lic pipe manufactured with purple (Pantone color No. 512, 522C, or equivalent) integral to the material. For either mate- rial, the tape or pipe shall be installed so the wording is clearly visible and shall be field or factory marked as follows:
