Many of them cut down the frequency of collection trips to once
or twice per week in order to save on transportation costs, and
also employ fewer labourers than as proposed in the official estimate
to cut down on salary expenses. Better services are offered
to high-income groups, who do not mind paying the private contractors
unofficially in order to keep their streets clean. An insufficient
number of bins has led to people having to walk a greater
distance to dispose of their waste; and low collection frequency
has kept the bins in an overflowing state. These factors prompted
people to resort to roadside littering, illegal dumping and indiscriminate
burning of MSW. Wastes from the overflowing bins
and street corners attracted cattle, dogs, cats and vermin.
