Storm Drain Opening 〈2025〉

Engineers select specific inlet designs based on the surrounding topography and expected water volume:

: A hybrid design featuring both a curb opening and a grate inlet to maximize drainage capacity.

: In Savage, Minnesota, public workers spent hours successfully retrieving seven ducklings that had fallen through a grate.

A is the essential gateway for rainwater and snowmelt to enter a city’s stormwater management system .
