Pollution Overview

Stormwater runoff in our city isn’t treated.

The storm sewer system is separate (with the exception of CSOs) from the sanitary sewer system. Because we don’t treat the water before it exits the system and flows into our waterways, we must do our part to minimize the pollution that enters into the system.

Rainfall and snowmelt pick up whatever chemicals, trash, or pet droppings that are left on land. This waste makes its way into our creeks and streams.
