How to redirect row from different tables with bad column data to a generic table?

We have about 20 source tables. There are columns in those source tables which may contain bad data and cause package to fail. I'm looking for some advice on how to capture bad rows on any table and redirect them to ONE generic table (because otherwise I'd have to add error dump tables for each source table and that gets out of hand very quickly,) and do this in a performant manner.

I'd like to do this with code, that is a custom component or script. 

Thanks!
