Sizing Catch Basin
Sizing Catch Basin
(OP)
Another basic item I don't know about. How do you properly design/size a catch basin? For example, if you are receiving say 1000 gpm, do you chose a bsin which can hold 1000 gal.? May sound like a dumb question, most people I know have just sized on gut feeling, no particular reference.

RE: Sizing Catch Basin
1. The capacity of the grate inlet.
2. The size and number of the drainage pipes coming to it.
3. For what has to go inside it as pump equipment, orifice pipes, ladders, etc.
4. The depth below grade of the bottom of the catch basin.
