Abstract
A storm sewer overflow control device for controlling runoff surge flows from a generally vertically oriented storm drain into a generally horizontally oriented storm sewer pipe includes an engagement portion configured for insertion into the storm sewer pipe, a flow control portion attachable to the engagement portion and configured for receiving runoff surge flow flowing down the storm drain and slowing the flow for entry into the storm sewer through the engagement portion. The engagement portion is radially expandable to tightly and frictionally engage an interior surface of the storm sewer pipe, and preferably is configured to expand radially as it is shortened axially.
