They have the advantage of being self-cleaning and are often preferred over grate inlets. Here are some key points about curb-opening inlets:- Useful in sag and on-grade situations.
- Placed outside the travel way, posing less risk to motorists and bicycle traffic.
- Capacity depends on water depth, curb opening length, and height.
- Covered with a grate or filter to prevent debris from entering the stormwater system.

Inlets in Sags – Learn Stormwater Studio
See more on learn.hydrologystudio.comThe capacity of a curb-opening inlet in a sag depends on water depth at the curb, the curb opening length, and the height of the curb opening. Curb inlets operate as weirs to depths equal to the curb opening height and as orifices at depths greater than 1.4 times the throat height. At depths in between, flow is in a transition stage.Curb-opening inlets are effective in the drainage of highway pavements where flow depth at the curb is sufficient for the inlet to perform efficiently. Curb openings are relatively free of clogging …
