Water for Nature, Water for People: Treatment Wetlands as a Tool for a Sustainable Water Supply

摘要

IN 2016 THE CITY OF LAKE CITY cut the ribbon on the first treatment wetland (see Figure 1) in the Suwannee River Water Management District. The successful implementation of this project has provided a viable option for rural communities seeking to sustainably manage water resources where other methods may be unavailable. The treatment wetland reduces reliance on a sprayfield, where treated wastewater is disposed of via spray application to a grassy field. Sprayfield disposal of reclaimed water provides some limited nutrient attenuation. Still, it does not achieve the advanced treatment standards that are needed to reduce nutrient concentrations at regional springs and does not maximize the recharge of treated water to the aquifer.
