That's a different question -- how to get 38,000 gallons

Heh heh ... I don't know if you know about California, but, the
forecast is for ZERO rain from now until about late November.

From November to about March, it can rain a decent amount, or,
as it did last year, it could skip us altogether.

This (dated) article said 4 inches fell from Jan1 to late September 2013.

And the winter of 2013-2014 was equally dry.
