This blog consists of archives from the original blog “Biological sand water filters and roof water harvesting” ; started back in July of 2008. That blog had documentation from work done on slow sand water filtration for 7 years. The blog was started a year after the study on slow sand water filtration started. The information from that blog will be slowly added here as time permits. Due to issues with data corruption, a migration was not possible.
On the forum, please try to limit the discussion to topics directly related to rainwater or roof water harvesting and slow sand water filtration.
On the blog topics will be introduced by the admin. Comments are welcome.
