Ever wonder what that random bare wire is sticking out of the ground near your gas meter or along the foundation of your house? No, someone didn’t forget to connect it to a circuit. Its purpose is safety! Let us explain… The underground infrastructure of our cities and towns is complex, carrying everything from water and gas to electricity and communications. For those in industries such as plumbing, like us at Aaron's Water Heaters, understanding the nuances of this underground world is essential. One such nuance is the use of tracer wires, which play a critical role in locating and identifying these utilities. In Michigan, understanding the color code of these tracer wires is pivotal. Here's a dive into what each color signifies according to the Michigan building code. What are Tracer Wires? Before we delve into the color codes, it's crucial to understand what tracer wires are. They're conductive wires buried alongside underground utilities like water lines, gas lines, or other conduits. These wires make it possible to locate the utilities later using an electronic locator, preventing potential damage to the infrastructure and ensuring safety during any excavation or drilling. Michigan Building Code: Tracer Wire Colors and Their Meanings The Michigan building code adopts the APWA (American Public Works Association) Uniform Color Code for marking underground utilities. Each color represents a different type of utility. Let's break down the significance of each: Red: Electrical power lines, cables, conduit, and lighting cables. The presence of a red tracer wire usually indicates that there's an electrical utility underground. Caution is advised. Yellow: Gas, oil, steam, petroleum, or gaseous materials. Yellow is a warning color, indicating potential flammable and hazardous materials below. Orange: Communication, alarm or signal lines, and cables or conduit. This color is generally associated with telecommunication lines like phone, internet, or cable TV. Blue: Potable water. Blue tracer wires lead to clean drinking water sources, and it's essential not to contaminate these lines during any work. Purple: Reclaimed water, irrigation, and slurry lines. Purple indicates non-potable water, used mainly for irrigation or industrial purposes. Green: Sewers and drain lines. Green tracer wires typically show the pathways of waste and stormwater systems. White: Proposed excavation. This color isn't necessarily for a tracer wire but is used in marking to indicate a planned excavation site. Pink: Temporary survey markings. Again, pink might not be associated with a tracer wire directly, but it is important in the realm of excavation and utility mapping. Why is Respecting these Color Codes Important? Mistaking one utility for another can have catastrophic consequences. For example, puncturing a gas line while thinking it's a water line can lead to explosions. Additionally, not locating utilities before digging can result in costly repairs, disrupted services, and potential legal liabilities. Hence, respecting and understanding the color codes is paramount.
