Civil engineers in Rome invented the concept of underground sewer to rid their cities of plagues caused by human contact with waste. Their water sources that they used for consumption were also contaminated as they served as open sewers. The underground sewers made sure that that waste stayed out of reach of humans and was deposited by these sewers further downstream. For periodic cleaning, they also provided access ways that were covered with stone lids that we call manholes today. Incidentally, these stone access way covers are still seen in Jerash, Jordan which was a Roman city in the old days.
Additionally, tree well grates play a crucial role in urban safety. They help to minimize tripping hazards by maintaining an even surface around tree installations.

Gate valves operate with a simple mechanism they consist of a gate or wedge that moves up and down to open or close the flow path. When the gate is lifted, fluid flows freely; when it is lowered, the flow is completely obstructed. This design allows gate valves to provide minimal pressure drop when fully open, making them suitable for applications where uninterrupted fluid flow is essential.
Installation Considerations
Tree grates are increasingly gaining popularity in urban landscaping, and one of the most favored materials for these fixtures is metal. Metal tree grates not only serve a functional purpose but also enhance the aesthetic appeal of public spaces.

The operation of a gate valve involves a gate, which is a flat piece of metal, being raised or lowered into the flow of water via a threaded stem or a handwheel. When the valve is fully opened, the gate is raised entirely out of the path of the flowing water, resulting in a negligible pressure drop and minimal turbulence. When the valve is closed, the gate descends into the flow, creating a tight seal that prevents any water from passing through. This functionality makes gate valves ideal for isolating sections of piping systems, allowing maintenance or repairs to be carried out without affecting the entire system.
