Stormwater quality associated with a full silt trap discharging into an urban watercourse

Scholz, M; Zettel, S

Abstract

The aim of this project was to assess the influence of a full silt trap on the quality of stormwater which was discharged into an urban watercourse. The average SS concentrations of the outflow were 2.0 and 34.1 mg/l during dry-weather and wet-weather conditions, respectively, and SS concentrations of up to 141.6 mg/l were recorded during storms. Treated stormwater SS concentrations were often high, compared with secondary sewage-treatment standards of ≤30 mg/l. Pollutants accumulated in the silt trap.
