Recycling of treated sewage wastewaters into two cypress domes in Gainesville, Florida is in its fourth year with much accelerated growth of cypress trees and recharge of groundwater after removal of most of the nutrients and microbes by the natural filter mechanisms of the swamps. The cypress swamps through the shielding effect of their thin leaf cover and their leaf drop in dry season save water, as compared to open water storage. Extension of studies to a cypress strand at Waldo receiving sewage for 43 years showed the long-term stability of the ecosystem receiving the nutrients. Drawdown of superficial groundwaters was found to occur a half mile from canals in south Florida. Lowering the water tables reduced the productivity and temporarily reduced transpiration. Evaluations showed that cypress swamp substitution for technological tertiary treatment was feasible.
