Alternate for Water Crisis
Our client takes pride in being considered as one of the premium and leading names in the Denim Textile and Apparel industry of Pakistan. With a strong global presence and affiliation with top garment industries globally, it takes the spot as the fourth largest Denim processing company of Pakistan and has three huge business units including Textile, Garments and Laundry.
The Textile Unit of the company utilizes state of the art machineries and equipment from prestigious international companies. The allied facilities make its infrastructure one of the most advanced in the Textile Industry of Pakistan. The Reverse Osmosis (RO) Plant is equipped with hi-tech equipment that purifies borehole water used in the plant, while it’s Effluent Treatment Plant (ETP) has the capacity to treat large amount of toxic waste discharging from different areas of the factory. Our client is the pioneer among denim manufacturers with an international standard laundry in Pakistan, with the capacity of 60,000 of garments wash per day. To run these two large business units our client industry requires bulk quantity of water which is fulfilled from KWSB water supplies, recycling of water by ETP/UF and borehole water. Our client had fourteen borehole water wells producing 20,000 to 45,000 USG per day. These borehole water wells vary in depths and range from 500 to 700ft. These wells pump borehole water from Manchar Formation. By the passage of time, borehole water production has depleted due to excessive use of whole INDUSRTIAL AREA OF KORANGI. Borehole water of Manchar Formation recharge from Manchar Lake and rain fall recharge at different exposures of Manchar Formation spread throughout the vicinity of province, the majority of Domestic users of Karachi city is fulfilling need of borehole water from this formation and big chunk of industry as well. Borehole water quantity of this formation is now reducing with time as the extraction is much greater than the recharge.
So, BNB investigated the whole scenario through electrical resistivity survey and suggested an alternate way to decrease this borehole water crisis by drilling a new borehole up to 1200ft into relatively un-utilized aquifer of Jhill limestone. This Jhill formation comprises of limestone and shale, alternate layering of confined aquifers under the sealed layer of Drig clay, both are the member of Gaj Formation. Due to the natural sealed of Drig Clay, its prevent the subsidence phenomena cause due to extreme extraction of borehole water from upper aquifers. Although the cost is relevantly too high, however our client decided to spend more money to SAFE the future of KARACHI and set an example for other INDUSTRIES as well. Currently, tubewell of our client producing 178,000 USG per day borehole water, which fulfilling his borehole water production need without vulnerable the city structures.
