No Wastewater Discharge Symbol - Environmental Compliance Icon #216636 (License: Personal Use)

The image features a bold red prohibition symbol overlaid on a black pipe releasing stylized blue water into a yellow background, representing contaminated or untreated effluent. The high-contrast design ensures immediate recognition and is commonly used in regulatory, industrial, and public safety contexts to prevent environmental violations. Its visual clarity supports multilingual communication where text may be insufficient.

Used on signage near industrial facilities, storm drains, or municipal infrastructure to deter illegal dumping; also appears in educational materials, compliance manuals, and environmental awareness campaigns targeting facility operators and the general public.
