Between the sanitary and stormwater sewer systems, there is a lot happening below the streets to protect streams, lakes, and wetlands.
The Sanitary Sewer System collects the dirty water that goes down our drains and toilets (i.e. sewage).
The word "sanitary" is confusing because it refers to the "sanitation system," not the water itself, which is definitely not sanitary! The entire drainage network of pipes must be well sealed to keep raw sewage from leaking out before the water gets treated. We also don’t want clean groundwater to enter the system because then we’re treating clean water. Too much water can also overflow the pipes and pumping stations before it gets to the treatment plant.

The Stormwater Sewer System collects rainwater and snowmelt runoff from streets, roads, driveways, sidewalks and parking lots to prevent flooding.
