This is an old idea, but not a bad one...  I recently saw a presentation
about rain cisterns (which is what the systems that catch rain water are
called) and one key was that the system shunted off water from the first
rain each year, as that water was DIRTY!!!  After that, it was filtered to
get out the big stuff only, the rest went right through the irrigation
system, but if I recall correctly, it was a conventional spray system which
I thought was pretty odd for water-poor Los Angeles.  Anyway, there are
indeed problems with running graywater (used household water) through drip
systems.  There is a whole body of literature on gray water and another on
saving rainwater.  I suggest you do a search on a decent search engine.
There is also a listserv on drip which last I participated, was called
"trickle-l", send a message to trickle-l@unl.edu.

Good luck!
