Cleaning waste water usually requires huge machines and tons of chemicals. The engineers from AYALA Water & Ecology figured out how to do it using only rocks, plants, and gravity.

00:00What you see here is raw sewage taken out from the septic tank, and this is water running
00:17out of the system that you see over here.
00:20We're doing it with zero energy, zero chemicals, and almost negligible maintenance.
00:24It's amazing.
00:26This is the power of nature.
00:57This place was contaminated.
01:00It smelled like fecal matter, urine, and all that.
01:18The community is without inhabitants because people have migrated because of the water situation.
01:25But it's not enough to keep them in the water or in a potable situation.
01:32So, it's a good project that's being presented here in the community.
01:38We're using too much energy in everyday life.
01:58We can do a miracle by mimicking nature and doing it in the right way.
02:02We're starting with the septic tank that receives sewage from the entire school over here.
02:08The sewage is running by gravity into these three ponds, going through this gravel.
02:15It's acting like a very powerful physical filtration, absorbing different kinds of contaminants.
02:21And we're using these plants that have a root zone that developed and support the huge communities
02:27of microorganisms, bacteria, fungus.
02:30And each one has another impact on the water quality at the end of the day.
02:35The outlet is very high-quality water that can be used for irrigation.
02:39The change is that we're using the water that we've already disposed of.
02:59To reduce carbon footprint in one hand, and to provide good water to communities all over the world, this is the future.
