Preface
This report investigates the effectiveness of street
sweeping as a stormwater pollution source control
measure. The Cooperative Research Centre for
Catchment Hydrology (CRCCH) Project U1 (Gross
pollutant management and urban pollution control
ponds) focuses on ways to improve the quality of
stormwater runoff. The project covered means to
reduce gross pollutants both before and after they
entered the piped stormwater drainage system. This
report describes a scoping study to assess the
efficiency of Australian street sweeping practices in
the removal of pollutants from street surfaces. This
study has provided information on the effectiveness
of street sweeping, currently practiced, in the
collection of pollutants across the range of particle
sizes representative of a street surface load.
It is a pleasure to acknowledge the contribution of
Tracey Walker and Tony Wong to the Urban
Hydrology Program. This work has provided
important insights into the limited role street
sweeping plays in improving stormwater quality.
