Sewage overflow is an issue in the U.S.
The EPA estimates that each year as many as 75,000 sanitary sewers overflow across the country, dumping untold gallons of untreated sewage into U.S. Waterways.

A decade later, the city changed course, deciding instead to reduce the amount of storm water before it reaches the sewers.
Rain gardens play a big role.
