Оранги: Пәкістанның Карачи қаласындағы қалашық

Municipality in Sindh, Pakistan

Orangi (, ) is a municipality approximately 22 square miles (57 km2) in an area that forms much of the northwestern part of Karachi in Sindh, Pakistan. It has often been considered of the world's largest slums. When grouped with the neighboring municipality of Baldia Town, the Orangi Baldia population is estimated to be over 2.4 million.

Following the Partition of India and creation of the Islamic Republic of Pakistan, a separate country for Muslims of India in 1947, a large influx of Muslim refugees from India began moving into Karachi. The Pakistani government began granting permission for refugees to settle on vacant land by 1950. Orangi Township was originally planned over by the Karachi Development Authority, and many of Karachi's squatter settlements were relocated here. The township was planned and developed with informal assistance from the city's municipal administration. Orangi did not qualify for government aid or community assistance, and the area's sanitation was extremely poor. in which the local community financed, designed and built their own low cost sewerage system. As a result of the sense of ownership, the community maintained the sewerage system and streets itself. though the Karachi Water and Sewerage Board eventually began providing water supply to the settlement. In December 1986, Pashtun gunmen attacked the Aligarh Colony, which was home to a vulnerable population of Biharis who had recently been repatriated from Bangladesh. Orangi is in fact a lower class settlement with basic amenities of life available to most of the people. Only some parts of Orangi Town can be characterized as a slum. At 22 square miles (57 km2) in size, it is "significantly less dense than most urban slums and also more structured". In comparison, Dharavi is home to one million people in about 1 square miles (3 km2). Ninety percent of Orangi's streets are connected to sewage services. Ninety six percent of homes in Orangi have their own private latrine or toilet. Most homes in Orangi feature two or three rooms. By 2004, over 90% of households in Orangi were connected to the city's electric grid, although up to 20% of connections were illegal.

Orangi's population alone is estimated to be over one million. When combined with neighboring Baldia, the population is over two million. The remaining 50% is a mix of Afghans, Balochis, Bengalis, Punjabis, and Sindhis. The project comprises a number of programs, including a people's financed and managed low cost sanitation program, a housing program that assisted in the construction of 93,000 houses, The OPP also helps provide education services, and as a result, the literacy rate in Orangi is higher than the rate in Karachi overall. Pipes are built under the street, with each household contributing $800 to $1000 toward construction of sewer services. "Lane managers" collect dues from households, and arbitrate disputes. The OPP model has been exported to other cities in Sindh and Punjab. OPP has also helped establish Awami tanks, which are underground water cisterns for use in a local area. Many are located under Orangi's mosques and churches.
