The others are water source from shallow soil-water digging and natural springs. There are 26 small ‘embungs' which have 11,700 – 96,830 m3 water volume and the biggest ‘embung' which has 1,860,000 m3 water volume; 276 springs, and some shallow soil-water digging. ‘Embungs' sustainability are influenced by some aspects such as technical problem since construction developed, utilization, social and management. Due to the natural resources and budget handicap, generally in one village just exist one type of the three water collected constructions. However, it is possible in one village there are three constructions, i.e.: ‘embung' is particularly for cattle drinking and irrigation; and the shallow soil-water digging and natural springs are specially for water domestic consumption. These man made and natural water source are very valuable to serve farmers in the Belu-ENT village area.
