Aloha,

Some more on catchment - the Texas Rainwater Harvesting Manual has a 3rd 
edition out just last year, available free here:

http://www.twdb.state.tx.us/publications/reports/RainHarv.pdf

See also publications from Oasis Designs (Art Ludwig, another 
arid-region designer) - his recently published "Water Storage" book is 
excellent on all the storage aspects, and they are working on an 
upcoming catchment book.  His greywater books are also excellent.

For about the ultimate detail on catchment, see "Rainwater Catchment 
Systems for Domestic Supply - design, construction and implementation" 
by John Gould and Erik Nissen-Petersen.  Ludwig and the latest Texas 
guide and others all mention this as a reference.  I have it - it may be 
overkill for your one project, but if you are intending to work with 
others, especially regulators who want lots of authoritative sources, it 
could be useful to have.

BTW ignore all those Rube Goldberg first-flush diverters in Mollison's 
books and derivatives thereof.  Use a variation of the simple 
no-moving-parts standpipe design shown in the the above references.
The Texas guide illustrates an IMO poor cleanout design with access via 
a plug at the bottom(!) of the standpipe, which is silly unless your 
standpipe bottom is up in the air and supported fully from above and/or 
sides.  Much simpler to let it rest on the ground and use a standard 
sweep 90 deg. cleanout at the bottom, with cleanout access plug 
(threaded) and self-draining hole or tap to the side.  That's what I've 
got anyhow.

cheers,
John S.
