What does the Purple USA marking indicate?

Explanation:
Purple marking shows reclaimed water lines. This means the line carries treated wastewater intended for reuse in non-drinking applications like irrigation or toilet flushing. It’s not potable water and isn’t for drinking. In the common US utility color system, purple is reserved for reclaimed water, while other colors identify different services (red for electric, yellow for gas, orange for telecom, blue for potable water, green for sewer). So seeing purple indicates you’re near a reclaimed water line and should avoid digging or activities that could damage it until you’ve confirmed the exact line and obtained the proper approvals.
