The principal watercourses are fourteen in number, with the most important amongst them being the canal that drew its water from the river near Harsul. Nahr-e-Ambari water course The city of Aurangabad had several water sources that supplied the city. These were deemed necessary as the city had a large military population to support. The courses that have been recorded are: A canal that branched at Gaumukh. One of these branches provided water to Shah Ganj and the surrounding area whilst the other branch passed the Barakul gate and provided water to the Naukonda palace, Juna bazaar and the suburbs of Chauk and Gul Mandi. One of the syphons has been damaged which is preventing water from flowing through it.

At present, the pipe is blocked with silt, with the result being that only a small amount of water can flow through in the wet season.
