biggest slum in the world
Orangi Town, Pakistan

Orangi town is evidence that slum dwelling is a continuing trend because the town is only about 12 years old. As expected in a slum, there are problems of sanitation, and this is compounded by the fact that there is no central planning in the area; structures are erected in clusters that make it virtually impossible to have a drainage or sewage disposal system. 

The good thing is that the people of Orangi Town are quite industrious; they power their own economy through small businesses such as jewelry-making, as well as the sewing of saris and slippers which may then be sold in the immediate environment, or taken to big cities for sale. Sadly, the rate of crime is quite high; as high as 77 percent of women have been victims of rape in the last 3 years.  

When the inhabitants of Orangi Town were tired of living without proper sanitation and a healthy environment, the residents gave up waiting for the government to mount sewers and built them by hand themselves. Presently over 8000 (90%) of Orangi Town’s streets and lanes have sewerage pipes, constructed by residents.
