The Greater Hyderabad Municipal Corporation has failed to curb the practice of dumping garbage in open drains by slum dwellers. With monsoon fast approaching, clogged drains are sure to create havoc once it starts raining. Officials fear that unless the slum dwellers stop dumping garbage, the city may witness severe flooding in several areas. After a lot of hue and cry, the civic body has now decided to supply tricycles in every slum where the major drains are situated for door-to-door collection of garbage.
