11.125.170 Water pumping station piping color code

11.125.170 Water pumping station piping color code.

(1) To provide a standard piping color code to be used in all water pumping stations.

(2) To provide quick and easy identification of all lines.

(3) To provide a guideline whenever station piping is repainted, replaced or added.

(b) Color Code. Only the pipelines listed in the following table will be color coded. Bare copper, stainless steel, and PVC lines will not be painted. If these pipelines carry potable water, no markings will be made. If they carry other process water (except chlorine) they shall be appropriately labeled. If they carry chlorine gas or solution, they shall be painted yellow except that flexible connectors, flexible vacuum tubing, and all chlorine valves and appurtenances shall not be painted.

When labels on pipelines are required (check with the Production Department) they should be plastic wraparound type, or self sticking type, which are commercially available. Arrows indicating the direction of flow should be of the same color as the lettering. In most cases, lettering and/or arrows will not be required.

*Indicates standard, commercially available labels.

All pumps and valves shall be painted the same color as the pipeline. Exceptions are that brass, bronze, copper, stainless steel, PVC and any flexible portions of these pumps or valves shall not be painted. If these items have been previously painted, then they should be repainted according to the above schedule.

(c) Cleanup. Cleanup and retouch as necessary all affected work. Leave all glass areas, unpainted fittings, plaster surfaces, floors and walks, hardware and other surfaces clean and free from any paint, stain, smears, spatterings or smudges.
