Kasur Tanneries Waste Management Agency (KTWMA)

Establishment

  • The government of Pakistan and United Nations Development Program (UNDP) signed the Kasur Tannery Pollution Control Project document in January 1996
  • UNDP allocated US$ 2.5 million, whereas the local input was Rs. 199 million

Inflow Wastewater

  • Comes in two drains from the Tanneries
  • Two drains comes side by side along the road coming from tanneries to the treatment plant

Flow Measurements

Drain 1

Width = 145 cm = 1.45 m
Depth = 54 cm = 0.54 m
Velocity of wastewater = 0.13933 m/s

  • Flow = 0.1091 m3/s
    • = 9426.32 m3/d

Drain 2

Width = 90 cm = 0.9 m
Depth = 54 cm = 0.54 m
Velocity of wastewater = 0.28575 m/s

  • Flow = 0.1388 m3/s
    •  = 499.94 m3/hr
    • = 11998.75 m3/d

Measurements

  • From Drain 1 ( Q ) = 9426.32 m3/d
  • From Drain 2 ( Q ) = 11998.75 m3/d

Total Discharge = 21425.07 m3/d

The treatment plant suspends all large particles from the discharge coming towards it. The pore size is of 60 mm. Furthermore, bar screening is done manually.
