A filter for catch basin can help you keep the water in your community safe and healthy. Water can collect contaminants from a variety of sources, but a filter for catch basin can remove many of them, giving you better, locally sourced water to drink. Stormwater drainage and stormwater runoff can introduce a range of pollutants into local water supplies and waterways, making them less healthy. Stormwater filters, like a catch basin filter, filter storm drainage as it flows into other water management systems, like local collection or drainage management systems.
Stormwater collects several pollutants from several sources, each of which can be harmful to a local water supply or waterway. Macroscopic pollution is the kind pollution that you can see, but a lot of pollution is microscopic. “Nonpoint source pollution” is pollution that does not originate from one specific source, but is gradually accumulated by water as it flows, so a lot of the contamination in storm and other water is nonpoint source and so is difficult to regulate and prevent. Water pollution generally consists of organic and inorganic pollution. Organic, or carbon based, pollution tends to include detergents, pesticides, petroleum waste, and hygiene product waste. Inorganic pollution generally consists of industrial discharge, some fertilizers, and ammonia. These are all things that do not belong anywhere near water that humans use, but flowing water picks them up all the time, especially where more people live.
According a study from the University of California, a filter for catch basin was able to remove over 80 percent of lead and over 50 percent of copper from the water that flowed through it. A filter for catch basin cannot remove everything completely, but it can significantly reduce waterborne pollution. Using several in sequence can help sift out a greater proportion of the contaminants.
