We want to prevent major flooding as much as possible. Sometimes it is also caused by overflowing of supposed to be a faulty drainage system. There are several causes of floods and overflowing of water in the urban streets. With constant heavy rain downpour, there have to be ways to counter the effects of heavy rain. That is why people have developed underground storm water detention in DC.
Stormwater detention is an underground framework principally constructed to manage excessive rainwater overflow caused by typhoons. These are usually developed in an urban area where establishments and buildings are cramped. They were designed to strategically manage the volume of rainwater that runoffs to different surface areas. This way it ensures an even distribution of all the liquid throughout different areas.
The system of an underground storm water detention creates more space above ground and paves the way for developing new establishments in steep areas. Since the pipes and storage are all constructed underground, it does not take up space that may be utilized for different kinds of buildings and establishments for economic purposes. Furthermore, this system also takes into consideration all the existing environmental guidelines and regulations.
These water basins are engineered to take in and house immense amounts of rain that comes from a storm. It is designed to temporarily store that kind of liquid and not hold it for the long term. It prioritizes flow control and follows a system wherein the all the stored liquid will be released at specific controlled intervals to avoid excessive flooding.
So basically, the process begins when rainwater from typhoons starts to fill the detention basin as it rises within the channel or the other establishments that are around it drains it into sewers. Following the continuous rise of the volume of the liquid inside the channels, it steadily fills the watershed from the pipes. All of the rainwater from the typhoon is then captured in the detention basin.
As mentioned above that this system relies on the laws of gravity, the speed of water flow depends mainly on the channels. The sooner the channels drain the water, the faster the basins also drain. If the movement is stagnant, it imposes a bigger chance of flooding streets and establishments that can cause unnecessary hassle.
The channel and the basin are codependent with one another. It needs the other one to execute its job properly for the other one to perform successfully. Once the water in the channels reaches a normal level, the basin can once again be empty. It is now prepared for the next storm, while still following the same process and the cycle goes on.
Among the greatest benefits of this smart engineering is the prevention of massive floods within urban areas. It can also lessen the erosion that the rivers may experience. However, this does not include the improvement of water quality since it only manages the liquid flow. Nonetheless, some existing watersheds attach a specific filter that removes all the unwanted trash and pollutants.
Overall this type of system lightens the impact of rainwater runoffs caused by a storm and showcases an effective space saving method. This process requires strategic planning and intelligent engineering. This solution follows the same process as to how nature naturally does it, people have just made slight modifications to improve this process. This has greatly helped humanity in improving the way of life since flooding can be hazardous to our health and can affect our daily activities. Ever since the creation of this system, it has brought a huge improvement and comfort in daily activities despite having to experience a typhoon.
