Subsurface Constructed Wetlands
08/10/24
“How can we filter wastewater by pushing it through toxin-absorbing plants?”
Wastewater typically contains toxins that prevent it from being used directly by humans. Certain plants can purify wastewater by absorbing these toxins. So what if we were to build a trench with impermeable walls, fill it permeable material like rocks, plant these toxin-absorbing plants on top, and then mechanically run wastewater through it? Well, that’s the idea behind Subsurface Constructed Wetlands. Subsurface construction is a great way to obtain recyclable water supplies while supporting plant life and not using dangerous chemicals.
