The uniformity of circular manhole covers also facilitates mass production. Since these covers are produced using molds, a circular shape allows manufacturers to streamline production, leading to lower costs and more efficient use of materials. Furthermore, the rounded edges help distribute weight evenly, making it easier for workers to lift and replace the covers without compromising safety.

Water management is a significant concern for urban planners, particularly in the context of climate change, which has led to unpredictable weather patterns and intensified rainfall. Efficient drainage systems are vital in preventing urban flooding, which can result in significant property damage and health hazards. Water manhole covers are strategically placed to allow excess rainwater to drain into underground reservoirs or treatment facilities. This capability significantly reduces the risk of street flooding during heavy rain and helps manage the water supply more effectively.

In commercial and industrial settings, gate valves are often part of the sprinkler systems designed to combat fires. These systems require high water pressures that gate valves can maintain effectively. The valves can be positioned strategically throughout the facility, allowing for targeted suppression in specific areas, thereby enhancing the overall safety of the building.
