What is the difference between the storm sewer system and sanitary sewer system?
The water that goes down the sanitary sewer system (from sinks or toilets) flows to a wastewater treatment plant where it is treated and filtered prior to entering any water bodies.

The stormwater and urban runoff water that flows down driveways and streets and into the storm sewer system flows directly to our creeks, lakes and rivers. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing and providing drinking water.
