Unimark System

Honolulu Board of Water Supply (Recyled Water): This method is an effective marking system...We are now able to differentiate the reverse osmosis reclamation, secondary reclamation and domestic water distribution pipelines.
Southern California Gas Company (Gas Services - High Pressure Pipeline): Saves valuable marking time and efforts…Gas service and meter locations are better defined to ensure revenue resources...no complaints from customers or the public about a graffiti appearance.
Los Angeles Department of Water & Power (Water Distribution) Great value with color coded identification, separating our recycled water and our drinking water supplies. The City Fire Department can now distinguish the fire hydrant valves from the main line valves.
City of Healdsburg, CA (Water Distribution): Easy to apply...we will continue permanent marking systems by Unimark.
City of Paso Robles, CA (Wastewater Collection): Being able to see the direction of flow from our service trucks upon arrival, will save the city valuable time setting up cleaning and video maintenance equipment.
