Catch basin = drainage inlet (a surface opening which collects stormwater runoff into an underground collection system).
I am familiar with hydroponder's use of the term 'sump'. However, a it is also a common term to describe the location of a catchbasin with respect to roadway grade.
When a catchbasin is located in the curb of a street along a slope portion the catch basin is "on grade".
When a catchbasin is located at the low point of the road/street it is "in the sump".
There are separate calculation methods for determining the amount of runoff captured and the depth of flow depending on whether the catchbasin is located "on grade" or "in sump".
RE: DIFFERENCE OF CATCH BASIN AND SUMP
A catch basin is a chamber, well or inlet designed to collect rain water which includes systems to collect debris and sediment and prevent the clogging of sewers
Catch basin: a depression, trench, or pit, which is a collection point for drainage, either water or spilled oil, that provides a means of containment for and prevents the uncontrolled discharge of the collected liquid from a facility or oil storage area.
Sump: a depression or trench constructed to collect drainage of water or spilled oil from storage, transfer or unloading areas.
In summary, the definition depends on the application and industry. A catch basin usually has an outlet to a drainage system. A sump usually does not have a gravity drain out of it.
