Techniques for controlling total suspended solids in stormwater runoff

Abstract

Stormwater runoff is the major source of total suspended solids (TSS) released into the environment. This paper presents a state-of-the-art review of techniques for removing TSS from stormwater runoff. Three main categories of techniques are presented: infiltration, filtration and detention. Infiltration trenches, infiltration basins and porous pavements are discussed as the common infiltration practices. Filtration systems include filter strips, grassed swales and media filters. Wet and dry detention ponds and constructed wetlands are the most common detention practices. Polymer-assisted stormwater ponds are also discussed. The function, performance and suitability of each technique are discussed, and a comprehensive review is provided to guide the selection of a suitable TSS control technique. © 2001 Taylor & Francis Group, LLC.
