What are Manholes? | Sewer School
Bollards, often made from materials such as steel, concrete, or recycled plastic, play a crucial role in urban design. Their primary purpose is to provide a physical barrier that prevents vehicles from driving into pedestrian zones, ensuring safety for walkers, cyclists, and outdoor diners. In cities around the world, you can see them serving as guardians of public spaces, effectively managing traffic flow while delineating areas for foot traffic.
Furthermore, the movement towards colored drain covers aligns with a broader trend of integrating art into public spaces. Public art installations have become increasingly popular as cities look for innovative ways to enhance urban experience and foster community engagement. Colored drain covers are a small yet impactful step towards this goal, transforming mundane infrastructure into opportunities for creative expression.
Historically manhole covers have been manufactured from cast iron [3], which is iron that is melted down and poured into a mold. When it comes to manhole cover material, gray cast iron and ductile cast iron are preferred as they are both economical and extremely durable. Gray cast iron is made up of iron alongside alloys including carbon and silicon. It is the carbon that results in the strength associated with cast iron. Ductile cast iron differs from gray cast iron because manganese is added to the molten iron during the casting process, which influences the formation of the carbon, resulting in an even stronger finished product.

Moreover, the global diversity in manhole cover designs reflects the unique identities of each locale. In the United States, many cities feature covers that pay homage to significant local landmarks, sports teams, or cultural heritage. For instance, some manhole covers in Chicago celebrate the city's architecture, while others in San Francisco may highlight its Golden Gate Bridge. This localized approach transforms an ordinary element of the cityscape into a storytelling medium, bridging the gap between the past and present.
