It becomes difficult to breathe while you are inside a construction site. The amount of dust that you can see all around the site will make you wonder how the employees are working in such a perilous zone. They might contact any air borne disease which could be quite fatal to them. Also comes into the mind the necessary steps the company is taking to keep the dust under control. Well, frankly where construction is in full swing, dust is bound to flow in the environment and nothing much can be done by anybody to contain it. However, there is one step that can be taken to contain dust and it is to sprinkle water at regular intervals so that the water pulls the dust on the ground and allows fresh air to breathe. But there are places where there is water scarcity in that particular area. In such places, even sprinkling water can be a problem.
In order to bring dust under control, there is no other medium other than spraying water on the ground and if at all there is any other way to contain this problem then that will be very expensive, probably out of the reach of many construction companies. They will certainly not want to invest a good chunk of money to keep the dust level under control. Though it is a must to equip and implement whatever process you can to keep the construction site dust free, construction companies would not want to adopt any expensive modes. So this leaves them with the option of spraying water.
For places where there is water in abundance, construction companies can store gallons of water in a storage tank and then later fill it up in a truck that has a pipe attached to it and then use the truck to spray water all over the site. By doing this, you make the process portable; which means you need not have a large pipe that goes across the entire corner of the jobsite. One can only imagine this and wonder how tedious it will be for the person who moves around the jobsite with the pipe spraying water. For a big construction site, using a water tanker that can move while spraying water is the best option. Please do not make use of fresh drinking water for this purpose. You will only end up finishing your resources sooner than you have thought.
You can make use of water that you get while excavating earth. Though the proportion of that water will be quite limited for your use, you can also make use of saline water of the sea. For that, you need to make necessary arrangements to port water from the seabed to the construction site. This exercise may prove to be a bit expensive but certainly advisable rather than exhausting the fresh water to control dust. Using nozzles while sprinkling water is recommended as it not only settles down the dust but also allows it to return to the ground making it a convenient process of dust control.
