This proposed study will provide a better understanding of the effectiveness of existing sump manholes
and catch basins by documenting sediment volume data from actual structures in urban watersheds.
Often influent concentrations in urban environments are assumed to have a particle size distribution
(PSD) similar to NURP 50 (EPA 1983), and this study will attempt to confirm if this is a valid assumption
for urban watersheds. This study will also illustrate how SHSAM can be used to estimate effective
maintenance schedules. Characterization of sump sediments will also provide a better understanding of
the pollutant hazard to the environment. Characterization will also provide an understanding of the
sediment disposal options available.
