Why Constructed Wetlands Provide Cost-Effective Wastewater Treatment
Quick fact
A constructed wetland can reduce biochemical oxygen demand (BOD) by 90% or more, achieving treatment levels comparable to conventional plants while using up to 90% less energy.
Why this is interesting
What if a wastewater treatment plant could be a beautiful, natural marsh? Constructed wetlands are doing just that—and saving communities millions of dollars in the process.
