Sewer Manhole with Open Lid

This is a circular manhole design, featuring an open lid revealing the inner ring. The lid, textured with an intricate pattern of recessed lines forming geometric shapes, is embossed with the word 'SEWER.' The material appears to be metal with a dark, slightly corroded finish, suggesting weathering or age. The ring around the opening has a similar weathered texture, reinforcing the impression of an object exposed to the elements.
