Gomal Zam Dam Multipurpose Project
 WAPDA Dera Ismail Khan

Main Headlines








Gomal Zam Dam site (Khajuri Kach), is located on Gomal River in South Waziristan Agency, west of Tank and D.I.Khan Districts of Khyber Pakhtun Khwa (KPK) Province. The site is accessible from Tank by and all weather road. About a couple of miles downstream of its confluence with Zhob River and Wana Toi, the Gomal River cuts through a narrow gorge, only 24.4m (80 ft.) wide at bottom, and about 183m (600 ft.) wide at top, offering and ideal site for high dam. The site is accessible from Tank by an all-weather road.

Objective / Benefits















(a) Main Objective

The main objectives of the project include: (i) irrigated agriculture development; (ii) hydropower generation; and (iii) flood protection.

i).   Irrigated Agriculture Development

The project will provide 316,232 Acre-Feet of water annually to irrigate about 77,353 ha (191,139 acres) round the year including: Perennial water rights covering 33,387 ha (82,499 acres) Culturable Command Area (CCA) and Flood water rights area comprising of 43,966 ha (108,640 acres) of CCA.

The Project would supply water to all the above lands. Cropping intensity would be 120% for the perennial (C1) and 100% and 60% for flood water right areas (C2 & C3) respectively.

ii).   Hydro Power Generation

The Project will provide cheaper Hydropower as compared to thermal power. A small power plant will be installed at the toe of the dam with installed capacity of 17.4 MW.

iii).   Flood Protection

The scheme will control the flashy floods, which has been causing damages to the fields, roads, bridges, canals, buildings etc. The recurring damages cause loss to the exchequer amounting to million of rupees in the repairs of these works. It is estimated that floods are causing damages amounting to Rs. 160.00 million per annum as highlighted in the Feasibility study report 1995.

(b) Other Objectives

Other objectives include: Employment opportunities in the industry and commerce, resulting from the processing of farm production; improved standard of living, resulting from the increased and more varied food production; security to farmers as a result of reliable water supply; balanced diet by providing opportunity to produce fruits, vegetables and other protein foods; water for domestic use; and road system being built.
