What is the difference between the drains in the street and the drains inside the house?

The drains in the street collect water in catch basins which ultimately flows into the ocean.  It is important that this water is not contaminated because it is not treated prior to flowing into the ocean.  Noxious agents can have a negative impact on the heath of the Harbor and surrounding ocean life.  (No animal feces, motor oil or other agents allowed in drains in street.)  Drains inside your house take waste material to the South Essex Sewerage Treatment facility to remove waste products.
