Advanced Ecologically Engineered Systems

An Advanced Ecologically Engineered System (AEES) is a wastewater treatment system that uses natural processes to treat water. The US EPA has conducted extensive research on AEES and constructed wetlands; and has concluded that these types of natural systems can often-times be the preferred sustainable ecological engineering solution to some of the wastewater problems we [...]
