ABSTRACT

In practice, a variety of structural storm water management systems are employed to improve water quality. These systems in part include vegetated swales, extended detention basins, wet ponds, infiltration basins, bioretention basins, constructed wetlands, and sand filters. In addition, there exists a variety of nonstructural storm water management measures, such as porous pavements, rain gardens, and vegetative buffers. In recent years, various water quality devices have been manufactured to address the federal and states water quality regulations. This chapter discusses manufactured water quality devices (also referred to as water treatment devices) and presents a brief comparison of these devices with structural water quality systems. Structural and nonstructural storm water management systems will be discussed later in this book.
