Passive ecosystem services, juxtaposed with engineered processes, can democratize wastewater treatment

Due to technological, economic and environmental constraints, contemporary treatment plants cannot treat all wastewater. In particular, the very high amount of agricultural and urban runoff to be treated is increasingly concerning, especially with more erratic — and unpredictable — rainfall events. Passive ecosystem services can be combined with engineered processes to create hybrid, locally adapted, inexpensive and sustainable technologies to more feasibly treat runoff and wastewater globally.
