If you are trying to do everything that you can to help protect the environment, something you need to consider is proper stormwater drainage which the government has been requiring effective measures in since 1990 thanks to the Clean Water Act of 1987. A study that was done by the University of California found that catch basin inserts that were placed in stormwater drainage sites were able to strain out 98.31 percent of fat or oil that were attempting to pass into the sewer system through the water. Utilizing top of the line storm drainage systems will ultimately help to get rid of both micro and macro contaminants that would otherwise wind up in local waterways.
The idea of nonpoint source pollution which is water contamination that comes from several sources that accumulate to create a large amount of pollution in a single area is exactly what proper stormwater drainage systems aim to prevent. Fortunately, the newest stormwater filters can catch just about anything in their grip. This means that as long as you have the right stormwater filters for your system, you can count on it being in good order to keep pollutants out of the waterways. More importantly, your stormwater management system will not take very much management on your part at all in order to keep it functioning. This means that it will keep going strong doing what it was meant to simply by you having it up on your property.
