(v) Connection to Utilities: During the construction of the manhole walls, connections are made to the utility lines, such as sewer pipes or storm water drains. These connections allow for access to the underground systems and facilitate maintenance and repairs.
Cast iron manhole covers are manufactured in factories known as foundries, with a casting process made up of five simple steps:
The ease of installation and removal is a crucial factor in the effectiveness of removable road bollards. Many modern bollards come equipped with various mechanisms, such as lockable systems, hydraulic lifts, or simple manual methods, making them user-friendly for city workers and event planners. Additionally, advancements in technology have led to the development of automated systems, allowing for remote operation of bollards. This convenience ensures that access can be managed efficiently without the need for extensive manpower or logistics.
However, the importance of the 18-inch manhole cover extends beyond mere access and safety. They serve as a canvas for artistic expression and community identity. Many cities have begun to commission local artists to design unique manhole covers that reflect the culture and heritage of their surroundings. These artistic covers not only beautify the environment but also create a sense of pride and belonging among residents.
Dual Functionality
Manholes are also periodically placed along the sewer or stormwater line for easy maintenance access. This placement varies depending on the diameter of the sewer or stormwater system in question.

Step irons are durable metal fixtures that are installed in the walls of pits or shafts. They serve as steps or rungs for miners to ascend and descend safely. These devices are usually made from high-strength materials to withstand the rigors of mining environments, including exposure to moisture, heat, and heavy wear. Their design typically features a textured surface to provide traction, helping to prevent slips and falls.
