Abstract

Hon Tre island with steep terrain, unconsolidated rocks and soils, the water flow in the streams are only in rainy season while dry season with no flow. Fresh water for the people on Hon Tre island is scarce and depleted whereas the forest area is decreasing. The main water sources are rainwater, dug wells, groundwater in the cave and under the rolling rocks. The water supply for people's life and economy is difficult due to the ability for water exploitation is limited. The proposed solution is to combine different water sources for water supply. Large-scale water supply systems are not recommended, instead, small-scale distributed water supply systems for group of households should be built. Priority way should be given for exploiting underground water, mountain spring water because these water sources are usually stable whole year with the limited water quantity but it should be fit for the small water supply structuters.
