Utility lines are generally buried at varying depths depending on their type:
- Cable lines, telephone lines, and pathway lighting wires are typically buried at about 1 foot (12 inches) or less.
- Sewer lines, electric lines, fiber optic cables, and gas lines are usually buried around 2 feet (24 inches).
- High voltage electric cables, water lines, and large sewer lines tend to be buried deeper, at around 3 feet (36 inches) or more.
The exact depth can vary by location, state regulations, and local conditions such as climate and soil. Some utilities might even be buried deeper due to engineering requirements or erosion. Specifically for gas lines, typical burial depth is at least 18 inches, with many buried around 24 inches deep. Utilities marking colors help identify different types of lines underground (e.g., red for electric, yellow for gas, blue for water). It's important to locate utility lines before digging to avoid damage and hazards. This information covers common depths but depths can vary, so checking local regulations and utility locators before digging is recommended.
