Greywater utilization....

the water situation here is critical during the summer months.... i can't see why a system couldn't be incorporated here, i just need a 'handy' person to help me... i found some directions on a very cool system... i can visualize a pond, perhaps only bathtub size, but seems that it could be utilized to water some areas of the garden... a cistern would be the ideal problem solver, but a shortage of cash and labour nixes that thought, at least for now...
found this tidbit of information for the future... Hansgrohe has developed a compact Greywater system which is supposed to be coming to the U.S. ... more more.. bring it on!!! North Americans in general are a wasteful bunch... and yes, i include myself in that group... i'm more frugal than a lot, but if i didn't need to be.. would i be??
