Water Supply in Karachi
The existing water supply network in Karachi is over 100 years old and has become outdated and defective. Most of the mains have outlived their useful life and require renovation and replacement.
The water demand of this thickly populated city is 492 million gallons daily, while the supply of water is limited to 355 (if nothing goes wrong). It shows a deficiency of water upto 90 MGD. This deficiency is likely to increase to 468 MGD by the year 2000, when the demand would be 820 MGD. The on-coming projects will however, take care of the part of the demand for all uses, thereby leaving a gap of 268 MGD between supply and demand for which new proposals will have to be drawn up.
Losses in water supply through leakage are 30 per cent. If this leakage is controlled, and 30 per cent is saved, it is sufficient enough to meet the water requirement of Karachi.
Karachi water and sewerage Board is taking certain
necessary actions to overcome this problem. Such as:
Scientific study has been initiated for Leak Detection
and Repair techniques under UNDP assistance through
