What is the storm grate?

Storm Grot is a lined metal opening usually along the curb on residential streets in cities, which is an entrance for rainwater outlet from storms. Usually the storm grate directs rainwater into an independent pipe that transmits it to a natural waterway in an untreated form such as a river or ocean. Many cities, however, tied their drainage grills directly into one set of pipes, which is part of the sewer system, instead of building two independent sets of underground pipes. This increases the volume load of the waste water treatment facility during storms and can cause untreated waste water at such times.

The storm grate proposals vary according to the location on the nation and climate. Cities or urban areas near a large natural waterway may have streets that do not contain any storm grates at all, such as some beach areas in the US, where drainage is directed directly to the Atlantic Ocean. Ocean City, Maryland, in the US, is a modern city that uses tstejná practice to rule out bOuřka drains completely in the city sections near the Atlantic coast. On the other hand, some cities, such as Kobe, Japan, are rated as among the cleanest in the world, partly because they have completely separate roads for drain in the rain, so that no untreated waste water is released into the environment.

cities like New York City, New York, in the US, which have a large underground metro, often have a double -purpose air ventilation and storm grate on the surface streets. This may result in a flood of the metro system during intense storms, as happened in New York in August 2007. The solution to such problems at this point was to increase the storm grate above the surface of the road, minimizing the amount of rain it caught during the storms, but it also acted as a ventilation shaft for metro.

drain of the bumper in large metropolitan areas are sometimes considered very harmful to the local ECThe region of the region, because the rain they capture, carrying any pollution or debris that raises from the city streets and buildings. Part of the solution is to create holes of the storm of the grate sufficiently fine slot pattern or grid, which can only wash the smallest residues around them. Immediately below the storm grate, depression is known as a basin that is designed to capture the remains that reach the storm grate. While these rainwater pits known as Gulley-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-the-thee-the -ings UK solutions, are effective in short-term solutions, they must be regularly drawn by the city using vacuum-powered equipment. The water itself is often directed to the waste sewer system, which can overload it and cause premature discharge of untreated waste water during intensive storms.
