Obviously the Sun is not shining at night. That is why the video talks about "24 to 48 hours", in a sunny day the water is processed in 1 day, and if it is cloudy it takes 2 days. They will need temporary storage tanks for the waste water to cover cloudy days, and catch up on sunny days.

Brilliant concept here, replicable all over the world. This illustrates what Bill McDonough says: "there are no wastes, only nutrients." http://foreignpolicyblogs.com/2010/10/06/bill-mcdonough-moving-from-less-bad-to-more-good/

oh, yes. this is calling also treatment wetlands! it is a natural process that use bio-organism that uptake nutrients from wastewater and produce clean water. The most common pollutants in wastewater are nutrients for plants and also for algae. I wrote something about this on my www.treatmentwetlands.blogspot.com and also about the use of algae to clean up the wastewaters.
