Karachi Nullahs Map 2007 is a detailed visual representation of the city’s documented natural nullahs and drainage channels. These nullahs serve as the primary conduits for sewage and rainwater disposal throughout Karachi. The map also illustrates the integration of these drainage systems with the city’s main sewer lines and Sewage Treatment Plants (STPs). It provides crucial insight into Karachi’s natural water flow patterns and existing drainage infrastructure, helping urban planners and researchers assess the city’s wastewater management and flood resilience.
