What is the difference between Median Inlets versus Grate Inlets?
When should each be used??


Grate Inlets are set with one side against a curb.  Therefore, they receive side flow along only one side of the grate (the length side), and the frontal flow is calculated using a typical curb and gutter section.

Median Drop inlets are set in the bottom of a ditch (Shallow Swale section on the Gutter Tab).  They receive side flow from two sided, and the frontal flow is calculated as a portion of the ditch flow.
