Abstract
Standard sumps are installed in many urban and suburban storm sewer
systems. They may
qualify as a best management practice (BMP) to pre-treat stormwater
runoff by removing
suspended sediment from the water. However, no data exist on the
effectiveness of sediment
removal and maintenance requirements of the sumps. Such data could
justify giving pollution
prevention credits to transportation departments, municipalities,
counties and other local
governments for the use of standard sumps.
The goals of this study were to (1) evaluate four configurations of a
flow-though standard sump
for sediment capture and washout; (2) design a simple retrofit for
standard sumps to improve
sediment capture and decrease washout; (3) develop a performance
function estimating the
efficiency of standard sumps in removing suspended sediments; (4)
develop another function
estimating the sediment washout in standard sumps. This volume of the
final report (Volume 1)
only focuses on the performance of standard sumps. The second volume
of the final report will
be on the design and performance of the retrofit for improving the
sediment capture and lowering
the washout rate.
