An improved street cleaning and a higher usage of water is
one of the suggestions to cities been given by the German “Länderausschuss”
for emission protection. This measure has a (very)
high degree of efficiency and requests only limited staff and financial
resources to be invested in case of an acute pollution with particular matters.
The instrument has been successfully used by the City of Vienna. At Leipzig, the possible realisation of this
action is currently investigated as part of the process towards an Air Quality
Management Plan in line with EU legislations.
The measure is qualified to reduce short-term existing or
forecasted episodes of PM-10 exceedences. Those
usually occur after long periods without rain, intense traffic, increased distance transports of fine particular matters,
through the application of scatter in winter and through increased expulsion of
dust through local construction activities.
This measure is carried out by an intensification of the
frequency of the usual street cleaning cycles in the target areas and an
increased application of water on the street pavement and the shoulder.
The efficiency of the instrument can be increased through
- the frequency and the thoroughness
of the cleaning
- modern technology of the
cleaning vehicles (in the optimum case, vehicles with clean fuels or at least
dust filters). |
