Roads
in any community collect dust, debris, and garbage almost every day.
From garbage scattered by stray animals to soil and mud left by
passing vehicles, roads are in a constant battle against dirt and its
harmful effect. Dirt and debris not only make roads look messy, but
they can also degrade their integrity. Furthermore, garbage left on
the roads can go straight into the drainage system, either clogging
the sewers and causing floods or emptying into the nearest river or
lake.
This
is where street sweeping becomes highly necessary. Normally, this
type of service is a responsibility of the public works or
transportation department, scheduling it on a regular basis. However,
there are instances when street cleaning must be done off schedule
due to excessive garbage collection such as after a parade or any
outdoor celebration.
Street
sweeping was originally done by human street sweepers using brooms
and other cleaning tools. To improve efficiency, street sweeping
trucks are used, especially when dealing with huge volumes of
garbage. Mechanical street sweepers take on large amount of street
dirt in a short period. They are often used in big cities where
collection of garbage on roads are more common, although some rural
communities also need their service during special occasions.
