Dead Coquis in catchment tank

[MarkP]

I don't think catchment water in Hawaii is more risky than anywhere else. As for catchment water in general, I don't have any statistics. I am tempted to say that I would prefer to control my own water supply rather than rely on a municipal system run by operators who are professional but who don't have the vested interest that I do. What are the real risks for both municipal systems and catchment systems? I don't know. I wouldn't be surprised if bottled water is just tap water, or if lots of dead things wind up in the county system. By the same token there are some pretty grungy catchment systems out there.

On the whole I am prepared to build a good catchment system with proper filtration and UV and use the water for everything.
