A slight diversion . . . .

This blog is associated with three other websites listed below. The focus of each site is different. Those websites and portions of this blog are all authored by the same person.
The three websites/pages are:
http://www.roofwaterharvesting.org
http://www,slowsandfilter.org
http://www.shared-source-initiative.com/biosand_filter/biosand.html
These websites along with the posts on this blog are all authored by me, Dave T; unless otherwise noted.
