The Wetland Cell @ CCWP

Instead of the customary rural septic system with a tank spilling waste water into an absorption field spread out over a broad area, the wetlands utilizes a natural biological and chemical reaction to cleanse wastewater.
It works like this: wastewater is routed from a septic tank into the constructed wetland. There, the bacteria that live around the plant roots naturally break down the organic matter in the water. Finally, the treated water drains from the other side of the wetland. It is a horizontal rather than vertical concept with only clean water sinking toward the aquifer. The smell, fortunately, should never make it into the open air.
The chemicals and processes that produce it will all be confined underground as part of an innovative piece of technology.
