    First concrete gravity dam completed in Sindh

    ISLAMABAD The first concrete gravity dam in southern province of Sindh has been completed at Nai Baran in Jamshoro district by a Chinese company and the Water and Power Development Authority (Wapda).

    A joint team of Chinese and Wapda dam engineers invited the media on Tuesday to visit the site.

    Wapda Hyderabad general manager (water-south) Amir Bux Mirani said that the project had been completed within the stipulated period of three years.

    According to the British Dam Society, it is called a ‘gravity dam’ because gravity holds it down to the ground stopping the water in the reservoir pushing it over.

    Construction of Darwat Dam by Sinohydro Corporation Limited began on June 30, 2010 at an approved project cost of Rs9,300 million, he said.

    It has a live water storage capacity of 89,200 acre feet and dead water storage capacity of 32,400 acre feet, he added.

    Gul Mohammad Junejo, the project director, said that this was a significant structure as it would irrigate 25,000 acres of barren land of the Kohistan area and additionally there would be round the clock water supply.

    “It has one main canal with a water supply of 156 cusecs and three other distributaries with a water supply of 156 cusecs.

    These canals and distributaries have a total length of 28 miles.


    Jamshoro and Thatta are the two districts that will benefit from the dam with the main reservoir of the dam’s site located in Jamshoro district and the irrigation system in Thatta district.”

    The project’s additional director Mohammad Iqbal Shaikh said that nearly all the canals and distributaries were ready except for one minor.

    “The residents of the area did not let us construct the minor because of a land acquisition issue.

    Miao Yu Liang, project manager of the Sinohydro Corporation, spoke about features of the concrete gravity dam.

    “The normal storage level of water in the dam was 112.55m, the highest flood level 119.86m and the top level 121m. Darwat Dam will store rainwater through Nai Baran river.”

    DERA ISMAIL KHAN:
    A 36-hour test run of the Gomal Zam Dam was initiated at 11am on Friday, Express News reported.

    If the test is successful, the dam will be made operational and will generate 17.4 megawatts of power, benefiting 25,000 households.

    The multi-purpose dam will irrigate 200,000 acres of land in district Tank and tehsil Kulachi, in district Dera Ismail Khan.

    The dam was inaugurated in South Waziristan on September 12 by then water and power minister Khawaja Asif, along with the US Ambassador Richard Olson and K-P Governor Engineer Shaukatullah.

    The project’s completion will benefit all of Khyber-Pakhtunkhwa where the present energy crisis has damaged the country’s economy, Asif had said at its inauguration.

    Re: Construction of Hydropower Projects and Dams

    Penny wise, pound foolish

    How much does Planning Minister Ahsan Iqbal think a 4,600-megawatt hydroelectric power dam costs? Leaving aside the seemingly poor arithmetic skills of officials at the water and power ministry, Mr Iqbal refused to approve a necessary project like the Dasu Dam because he believes that it can be completed for cheaper. While accountability for the use of public funds is important, losing sight of the larger strategic picture is a far costlier blunder.

    Let us examine some of the facts. The water and power minister is estimating that the project to build the Dasu Dam will cost around Rs735 billion, or about $6.9 billion. In other words, the installation cost of the hydroelectric power generation capacity at Dasu comes to about $1.5 million per megawatt, which is very cheap by both global and local standards. For the sake of comparison, a run-of-the-river dam set up by Hub Power Company in Punjab cost about $2.5 million a megawatt of installed capacity. Indeed, if anything, we believe the water and power ministry’s estimates are still too low.

    We would remind Mr Iqbal of what his former professors at Wharton would no doubt have taught him about capital budgeting: the longer one waits to execute a project, the higher its cost. Pakistan desperately needs to reduce the weighted average cost of power generation and, by far, the best way to do that is to install more hydroelectric capacity. Of all the major projects under consideration, Dasu is the cheapest option.

    In fairness to Mr Iqbal, the water and power ministry did itself no favours, first by using incorrect numbers for the exchange rate with the US dollar, and then by going directly to the Executive Committee of the National Economic Council rather than first sorting out the matter with the planning ministry. But Mr Iqbal should not throw the baby out with the bathwater. Yes, the power ministry made an error. But that error should be corrected, not compounded.

    Hydroelectric projects, dams could be win-win for Pakistan

    Pakistan's hydroelectric power operators could be significantly vulnerable to climate change given the country's significant lack of water storage capacity, according to a report published by the Thomson Reuters Foundation.

    Citing a World Resources Institute study that ranked it amongst the world's most water-stressed countries, Pakistan's Minister for Planning, Development and Reform Ahsan Iqbal said the country's stored water capacity is only adequate for about 30 days.

    "In Pakistan, planners and policy-makers across different sectors -- including agriculture and industry, energy and health -- now have a daunting challenge before them of increasing the country's water storage capacity," Iqbal said.

    The minister said Pakistan needs a minimum of 40% of approximately 115 million acre-feet of water available in the Indus River system, though the storage capacity now is about 7% and decreasing with sediment buildup.

    Pakistan's need for water storage infrastructure is compounded given the country's susceptibility to flooding.

    According to a report published by UN-Water, Pakistan ranks ninth among countries most affected by floods, making dams a critical component not only for water storage, but also water control.

    Pakistan seems to have taken note, however, as the country has announced a number of hydropower- and dam-related infrastructure projects in recent months, including the 740-MW Munda and 35-MW Harpo, 83-mw Kurram Tangi, and 128-MW Keyal Khwar plants.

    PM lays foundation stone of Dasu project


    KOHISTAN:
    Laying the foundation stone for the Dasu power project, Prime Minister Nawaz Sharif said the project would prove to be a milestone for the country and help resolve the energy crisis in the country, Radio Pakistan reported.

    Addressing the groundbreaking ceremony of the 4,320 megawatt power project, PM Nawaz said hydel resources will be fully exploited in order to overcome the electricity crisis. He went on to add that work on the Diamer-Bhasha dam would begin soon.

    The World Bank has agreed to provide assistance worth $1 billion dollars for the project, which is expected to be completed in two phases; the first phase will be completed in five years and will add 2,160MW electricity to the national grid.

    The premier also said an additional 40,000 megawatts of electricity could be generated from new power projects on the Indus River. At present, 7,000 megawatts of electricity is being generated from these projects.

    The Dasu project is part of the least-cost energy production plan of Wapda aimed at harnessing the country’s hydropower resources to improve the share of hydroelectricity in energy mix.

    The project will be constructed on the Indus River, seven kilometres upstream of Dasu village and 74 km downstream of Diamer-Bhasha Dam. The project is situated on the Karakoram Highway, about 350 km from Islamabad.

    According to a statement issued by Wapda, the priority is to construct Diamer-Bhasha Dam for which land acquisition process has already started and 13 contracts for offices, colonies and roads have been awarded.

    Dasu Hydropower Project will follow the initiation of work on Diamer-Bhasha Dam. Detailed engineering design, for which the World Bank is providing funds, and tender documents are likely to be completed in early 2013. Afterwards, construction work will commence.

    The project will generate 21.3 billion units of electricity per annum and will also have positive impact on existing hydropower stations including Tarbela, Ghazi Barotha and Chashma.

    Jagran hydropower project: Flouting of rules cost national kitty Rs400m

    ISLAMABAD:

    The Power Development Organisation (PDO) of Azad Jammu and Kashmir (AJK) has caused a loss of Rs400 million to the national exchequer by using dubious processes for issuing the contract for the 48MW Jagran-II hydropower project.
    This was revealed in a document presented by the lowest bidder firm Sino-Hydro HrL-JV partners at a meeting of the National Assembly Standing Committee on Planning and Development.

    According to the document, the PDO has breached several rules when awarding the contract on July 4. The contract was awarded to CWE/Sachal Joint Venture partner, the second lowest bidder, in breach of due process. The document says that a minority vote was used to determine the outcome and the bidding process prescribed by the Public Procurement Regulatory Authority (PPRA) was flagrantly ignored.

    Moreover, the document revealed that while selecting the bidder, the AJK violated Clause 35 of the PPRA rules, which require procuring agencies to announce the results of the bid evaluation in the form of a report and provide justifications for their decision at least 10 days before awarding the procurement contract.

    The PDO adopted a new and highly questionable system of ‘voting’ while deciding this matter, the document said. Usually, boards of government departments do not take such decisions through the voting process. Conversely, the decisions are taken according to the rules regarding the bid evaluation process determined by the Pakistan Engineering Council (PEC), PPRA and the guidelines of the loan-giving agency.
    A decision to award a contract for development projects should never be based on the overall strength of the member of the development committee.

    The document added that AJK government seems to have treated the project as a legislative business which is not only unique but also an unwarranted and illegal way of deciding the fate of a development project.
    It was also mentioned in the document that the PDO has also ignored the directives of the ministry of Kashmir affairs. The ministry is the principal accounting authority for the project. Recently, its secretary had been appointed as the chairman of the steering committee to ensure that all regulations were adhered to.

    The ministry had directed the PDO to set up a review committee to deliberate on grievances of the affected firm. However, the document revealed, that this has not been implemented. Furthermore, the document said that the views of the minister in charge of power in AJK and the federal nominee on the PDO Board were also ignored.
