A storm drain marker program was launched in fall 2010 to raise awareness about the relationship between water quality and the stormwater system. Student workers have been working with facilities staff to install the markers on storm drains within the campus triangle. Storm drain markers help prevent contamination and reduce the amount of pollutants that are transported through the stormwater system to local bodies of water. 

 

 

 

 

How is a storm drain different from a sanitary sewer?

Storm drain


When water flows across pavement and down a storm drain, that water is piped directly to the nearest stream or lake; this water does not go to a wastewater treatment facility.  The purpose of a storm drain is to channel excess stormwater away from developed areas to prevent flooding. 

 

Sewer Cover

Sanitary sewer 


On the other hand, the sanitary sewer carries wastewater or sewage from toilets, kitchen and bathroom sinks, showers, tubs, dishwashers, and washing machines through an entirely separate underground piping network from the stormwater system. The wastewater is transported to the wastewater treatment facility where it is treated to remove biological nutrients prior to being discharged.  Manhole covers allow access for maintenance, but there are no open drains or grates.
