The ideal modern system collects storm water separately from wastewater and treats it to remove all pollution, but that has become a difficult task. There are four different types of wastewater pollutants and all four are treated before being released.

The primary treatment in removing pollutants from wastewater is the removal of the first type of pollutants, debris and grit; like, plastic bags, gravel, course sand, rags, and other object disposed in toilets or washed through storm drains. These pollutants can later damage or clog pumps, so they are quickly removed after exiting the raw sewage. This removal involves two steps; screening of debris and...
