Sanitary Sewer Manhole Cover - Infrastructure & Utility Design #3544324 (License: Personal Use)

The image shows a circular cast iron manhole cover designed for sanitary sewer systems, featuring a robust interlocking woven grate pattern that provides structural strength and slip resistance. The raised lettering “SANITARY” at the top and “SEWER” at the bottom clearly identifies its function, while two side slots allow for lifting with specialized tools. Its dark metallic finish suggests weather-resistant coating for long-term outdoor use.

Used on municipal websites, civil engineering resources, or utility safety guides to illustrate proper identification of sewer infrastructure; matches user intent for understanding public works signage, asset management, or urban planning visuals.
