Catch filters and a catch basin insert are extremely beneficial to the environment because they filter out over 98 percent of fats, grease, oils, and other contaminants found in rainwater runoffs, according to researched performed by the University of California. Stormwater drainage systems are used for stormwater management purposes that involve benefiting the environment and the people. Stormwater pollution involves both macroscopic and microscopic pollution. Macroscopic pollution mainly involves floatables that are found in stormwater runoffs. A stormwater drainage system should include stormwater filters in order to prevent pollutants and contaminants from entering into the water supply.

Drop inlet spillways provide many advantages, including being totally contained. Drop inlet spillways do not require soil conditions to be resistant to erosion. One of the most cost effective ways to separate oil and water involves the use of storm drain filters. Stormwater drainage systems should contain drain filters to prevent oils from entering the water supply or ground water as well. Underground aquifers can be contaminated with pollutants if the proper stormwater drainage system isn’t being used. Chemical, biological, and physical assessments are made to water in order to measure the health of a waterway. Finding stormwater drainage products is best done online.
