Engineering:Scruffy dome
From HandWiki
A scruffy dome is a steel grille that is placed over the inlet of a manhole, and is usually dome shaped. They function as a way for stormwater to enter the pipe network without allowing larger debris in, such as people or animals.[1][2] Scruffy domes are usually placed in parks and wetlands, and are usually made with galvanised steel.[2]
