Popis: With two monsoons producing 2,131mm (in 2015) of rain, Sri Lanka records around 130 billion cubic meters of water annually. Rainfall which is captured and stored by tanks are distributed through 103 natural river basins. 50 billion cubic meters of water that remains after evapotranspiration and seepage is being released to sea without being utilized properly. Divided by 20 million population, a citizen can use 4000 cubic m3 of water per year but the actual demand stands at 73 cubic meters. However, Sri Lanka is a tropical island where ¾ of its land area, 6 out of 9 provinces is climatically defined as the dry zone. Hence it is clear that there is an unequal distribution of water in Sri Lanka. Using a flexible water bag as a mode of bulk water transportation has been tested and practiced successfully in countries like USA, Norway and Suriname. Findings will depict the possibilities of using a flexible water bag as a mode of bulk water transportation to address water scarcity in the dry zone. Secondary data were used to examine the availability of surplus water in the island and also to identifythe density and discharging quantities of water from natural river basins. A descriptive methodology has been used to find the feasibility of implying a flexible water bag as a mode of bulk water transportation in Sri Lanka.
