The study revealed that a total of about 208 Million litres per day of waste is discharged into the river by these drains amounting to about 8 percent of the dry weather flow, The BOD and Suspended solids contributed per day amounts to 52300 kg and 8810 kg. The major pollution is contributed by the Haider Canal and sarkata nala which bring basically the domestic waste. The authorities should take up the problem immediately either to provide treatment units to combat this heavy pollu-tion or to lay an intercepting sewer to collect these nala waste waters and discharged them down stream of the city to avail self cleaning capacity of the river.
