One of the more common catch basin sizes is 24" x 24" inside width with a 36" x 36" outside width, but it is not uncommon to see 36" x 36" and 48" x 48" (or larger) inside wall dimensions. The rim elevation is where the point where overflows are measured from, so an accurate rim elevation is important. If you know the invert of an outfall you can back calculate the node invert elevations of the other nodes from the length of the link and the slope of the link, Or if you have GIS software use a DEM or Tin to estimate the Rim Elevation of a node and then you can calculate the invert elevation. Frame height and vertical pipe clearance can also force a rim abovesurface. "Bottom of the inside wall" is what I should have said - thinking one thing, typing and posting another. You have to start somewhere with a known invert elevation. Rim, on a manhole, also Top of Grate on an inlet, is the elevation of the top of the cover on the manhole, or the inlet grate on an inlet. if I have a junction node with known depth, how do I estimate the invert elevation??
