What is the international color code for sanitary sewers?

The international color code for sanitary sewers is red. This coding system is used to ensure that different types of underground utilities are easily identifiable, helping to prevent accidents during excavation or construction activities. The red color specifically signifies that the pipes or infrastructure in question are related to sanitary wastewater.

Sanitary sewers are essential for directing wastewater away from buildings and into treatment plants, and clearly marking these systems helps to maintain safety and efficiency on construction sites. Using a standardized color helps construction workers and engineers quickly recognize the presence of potentially hazardous materials, ensuring proper handling and maintenance protocols are followed. As a result, knowing the correct color coding is critical for safety and compliance in the field.
