  • 1. Prevention of Water Pollution by Control of Sediments Sediment is a naturally occurring material such as soil, debris and pollutants that is broken down by processes of weathering and erosion. Through rain the sediment can travel from a site and run into the drains and gutters entering storm water systems and ending up in the lakes, wetlands, rivers and finally the sea. Soil erosion from construction sites causes major environmental problems for waterways and aquatic life. Sediments washed to waterways have a great impact on the habitats of aquatic flora and fauna. Sediments also block the storm water drains thereby increasing the risk of floods. Hence to prevent the habitats of flora and fauna and to avoid the environmental problems, Sediment Control is important. A practice or a device that is designed to keep the eroded soil on a construction site, so that it does not wash off and cause water pollution to a nearby stream, river, lake, or sea is what is known as Sediment Control. These devices are used to keep Sediment in Control. Sediment controls are usually utilized together with the erosion controls, which are designed in such a way so as to prevent or minimize erosion and thus reduce the need for sediment controls. Sediment controls are generally designed for temporary measures, but, some can be used for storm water management purposes. Some of the commonly used methods of Sediment Control are: Check dam Diversion dike Fiber rolls Sand bag barrier Sediment basin Silt fence Storm drain inlet protection Straw bale barrier For preventing the Sediment Control, the most effective method is to create a fence that keeps sediment in control. This method is also called as Sediment Control Fence. The geotextile fence provides the best way to control the sediments and if installed and maintained correctly, it can last up to six months. They are designed in such a way that it allows the flow of water even through the trap soil. The straw bales should only be used in synchronous with sediment forces as they have limited life span and start polluting the drains when they break down. These fences have a lot of advantages as well, such as 1. It avoids the soil and unwanted debris to enter the Storm water. 2. Ideal for use on Construction sites and Industrial Estates. 3. Can be installed easily using star pickets. Because of the advantages of using fence for controlling sediment, it is defined as the most efficient method.
