Storms and Extra Water
When it comes to grates, one of the first types to come to mind for many is drain grates. Not only can they be found on every street, often with little kids nearby tossing in rocks or sticks to see how deep they go. They are also seen in many parking lots and in the corners of some houses at the end of gutter pipes. The purpose of these products is to drain excess rain and ground water. Without them, roads could quickly become flooded in a mild rainstorm, making them impossible to drive on. Storm drains can come in many forms depending on exactly where they are located. Old drains might have just been criss-crossed pieces of metal attached to the ground. Today, the common type found in the United States is a grate attached along the side of the road, connecting to the curb while the drain itself is at the level of the road.
Steel storm drain grates are able to gather the excess rain and runoff and transfer it, often draining into a nearby body of water. Small drains may also be able to distribute the water to a piece of land, however large amounts could cause the land to flood. Products such as these have been around for roughly 4,000 years. The Romans and other ancient civilizations were able to use them to collect runoff. Often these models were made of stone, while today steel and other metals are more common. While they provide countless advantages, they still must be treated with care. Since they often run into other bodies of water, people must be careful not to toss garbage and waste into them because it will increase pollution levels. Many areas now instill an extra grate to catch any of the waste before it can impact the environment.
