The Accumulated Rain Water is Stored in 12 Dams Constructed | Bahria Town Karachi
At Bahria Town Karachi, the accumulated rain water is stored in 12 dams constructed; 167.6 million gallon water has been stored during recent rains.
Bahria Town Karachi developing more dams & increasing the capacity of the existing ones and up the storage in next 4 to 5 months to 275 + M gallons.

It is good to store rainwater. Will this be treated and made potable also?
Overall work in BTK seems to have slowed down.
