The Patiala Ki Rao is a seasonal stream that originates in Shivalik Hills, Punjab, enters Chandigarh then to Mohali and later merges into the Ghaggar River.[1] The stream runs across Fateh Burj at Chappar Chiri. It is one of the seasonal rivulets amongst others in Chandigarh, which include Sukhna Choe in the East and N Choe[2] in the West.
UT panel raises Patiala Ki Rao pollution with Punjab due to a significant increase in Nayagaon's population.[3] On 31 July 2010, Punjab Pollution Control Board reported that effluents discharged in N-Choe from Chandigarh were beyond the permissible limit. The analysis revealed that pollution levels such as BOD-150 mg/1 and COD 320 mg/1 was found to be more than the permissible limit of 30 mg/1 and 250 mg/1, respectively.[4] Mohali residents complained that the N-choe was not properly protected and that sewage was found in the water.[5]
