On June 18, 2015, the Japan International Cooperation Agency (JICA) signed two grant agreements (G/A) with the Government of the Islamic Republic of Pakistan to provide grant aid of up to 4.17 billion yen for the Project for Energy Saving in Water Supply System in Lahore and the Project for replacement of pumping machinery at inline booster pump station and terminal reservoir in Faisalabad.
These cooperation initiatives will supply safe water to urban areas of Pakistan where the rapid rise in population is putting immense pressure on the existing urban water and sewerage infrastructure.
The projects under the grant agreements are described below.
(1) The Project for Energy Saving in Water Supply System in Lahore (grant amount: 2.554 billion yen)
The pumping capacity of many of the tube wells in Lahore, Punjab Province, has dropped significantly due to deteriorating pumps and other factors, resulting in inefficient energy use when pumping water. In addition, due to the effects of rising power rates and the like in recent years, the cost of the power for pumping water reached approximately 45 percent of the operating costs in 2012, putting a significant financial burden on the Lahore Water and Sanitation Agency. The stable operation of the water supply and sewerage system requires fiscal improvements in the Lahore Water and Sanitation Agency, and cutting power costs is a priority area for such fiscal improvements.
With the objective of achieving a sustainable, stable water supply service, this project will update deteriorated tube wells in Lahore, restoring the well capacity that has dropped, and improving the energy efficiency of the water supply equipment. It is expected that the power consumption of well pumps will become more efficient, more water will be transported from the target wells, and the number of pump malfunctions will drop, reducing operation and maintenance costs.
(2) The Project for Replacement of Pumping Machinery at Inline Booster Pump Station and Terminal Reservoir in Faisalabad (grant amount: 1.616 billion yen)
Approximately 55 percent of the amount of water supplied to Faisalabad, Punjab Province, is reliant on the Chenab River watershed, but as more than twenty years have passed since installation of the core water supply facilities, factors such as deterioration of the booster pumps at the inline booster pump station mean that the entire capacity of the water source wells cannot be utilized in transporting water. In addition, pump failures occur on a frequent basis at the terminal reservoir, which not only reduces the stability of the water supply service, but also results in an inefficient use of energy by the pumps in water transportation and distribution, causing an increase in the costs associated with the energy consumption for pump operation. The rise in power rates in recent years has caused a strain on the finances of the Faisalabad Water and Sanitation Agency, and in 2013, the power expenses for pumping water reached approximately 29 percent of the operating costs. Given these circumstances, updating the pump equipment, stabilizing operation of the current facilities with the problem of deteriorated equipment resolved, efficiently using energy to reduce water transportation costs, and improving the operating conditions are priorities.
With respect to the water distribution reservoir of the Chenab River watershed, as the water intake volume increases with the vertical distance between the transportation pump installation location and the reservoir water level, and there is a design issue in which cavitation occurs when water stored in the lower half of the distribution reservoir is used, the water demand during the peak use period each day cannot be met when the distribution reservoir is half full. In addition, there is a loss of approximately 600 cubic meters of reservoir water per day due to factors such as leaks in the terminal reservoir wall caused by deterioration, and addressing this issue is a priority.
This project will update the inline booster pump station at the water supply facilities using Chenab wells as their source, as well as updating the pumps at the terminal reservoir in Faisalabad, stabilizing facility operation, making energy consumption more efficient and reducing water transportation costs, thereby achieving the objective of a sustainable, stable water supply system.
In addition to these projects, JICA is combining technical cooperation to improve management and develop human resources at five water and sewerage companies in Punjab Province, thereby providing support toward achieving sustainable stable water supply services in Pakistan.
