The stormwater runoff carries with it different types of pollutants including the floatable trash, debris, coarse sediments, hydrocarbons and others. It is important not to let these pollutants enter the stormwater stream or it can jam the flow of the runoff water. Once the passage is jammed, it becomes difficult to locate the part where the blockage is located. Preventing the entry of sediment and debris in the stormwater passageways is a better solution. It can be done with the help of stormwater inlet filters.
These filters are available in different designs. The multilevel screening system has different sizes of screens at each level. The media filter removes certain types of debris. A full capture filter removes 100% trash and debris. The type of filter selected for a curb depends on the types of debris and trash expected to enter that part of the stormwater inlet. It is important to use high quality product that will last several years. It ensures lower maintenance cost. A stainless steel filter lasts more than 25 years.
