Beginning with an overview of the types of natural treatment systems, this book outlines the planning, feasibility assessment, and site selection processes unique to natural processes as well as the basic process responses and interactions governing natural systems. The authors discuss wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. They illustrate the practical aspects through 30 examples; include 178 data tables for comparing costs, performance, and constraints; and describe new approaches to partially mixed ponds, including dual-powered aeration ponds.
