Have you ever been near constructions sites or near water, there are these strange large sacks that are by the roadside that resemble deflated or partially inflated balloons. These are not just ordinary big pillows that you see in the market, these are actually dewatering bags or sediment filtering bags that are used in filtering water.
As the image given below shows, these bags are employed in a sediment filtration process. Now let’s dissect the functionality of the water bags and the reasons as to why it has become popular in the water management.
Construction activities taking place near water bodies tend to displace water and sediment and thus pollute the rivers, lakes or streams. This is rather dangerous for aquatic systems since such water is essential for the life of these ecosystems. Suspended sediment can harm the fish gills, limit the amount of light to reach the plant and ultimately harm its photosynthesis and even hinder the working of municipal drainage systems.
This sediment has to be well managed as this can cause an adverse effect in the environment and may pose danger in construction activities or road construction and maintenance. That is where these sediment filtering water bags come in.
