Most people have either seen or used on of the little catch basin inserts in the bottom of their sinks, so that when they are doing dishes, or something like that, water can flow through and the debris get caught so they don’t plug your sink, stormwater filters are the same thing, but they just work on a larger scale. The specific filters used in stormwater treatments are called Catch filters, that can strain over 98 percent of liquid items that pass through them in the water, according to a study by the University of California.

Rather things are intentionally thrown out in certain locations, or just used in an everyday manner, many of everyday items like, hygiene items, personal care items, foods, detergents, items that are used outside to protect people from bugs, items that are used for cars and so on, are all considered organic water pollutants and they are all things that lead to stormwater pollution.

Although there is a variety of strange things that find themselves down in the drains, like an old shoe or sock, there are some really common ones that are seen all the time rather it is in the stormwater treatment plant, or laying in one of the catch basin inserts. Some of the common things that many people have in their cars are actually three of the more common waste materials that are caught in stormwater filter; candy and food wrappers, cigarette butts and discarded paper, these things usually get caught in the storm drainage as long as it enters at a certain location and do not make it any further than that.

Things that can potentially contaminate a large or small amount of water, but that enter in one source way, such as a broken pipe is called “Point source water pollution”. ?”Point source water pollution” means that the items, gum wrappers, trash, candy bars and so on came in through a way that is not used normally by stormwater treatment and they were not able to be stopped by any of the usual filtering methods because of where they came in. These pollutants have to be addressed and filtered through the systems through filters or even sweeping out of the water, like some people do in pools, at the stormwater treatment plants, which always have backups in place in case something of this matter was to occur.
