The objectives of this research were (1) to study the use of the land within mountain tap water area (2) to study a physical quality of mountain tap water such as turbidity, temperature, suspended sediment, acidity and alkalinity and electric conductivity (3) to compare the physical quality of mountain tap water with the standard of water consumption productivity (4) to study the relations of the physical quality of mountain tap water (5) to know the problem conditions and to search the way of how to manage the mountain tap water system efficiency by collecting water samples of 12 stations and there would be needed to analyze once a month since June to December 2012. The statistic used in this study consists of the average, the standard deviation, the T-test, the F-test and the Pearson correlation The results showed (1) the water source was a forest area the weir point was an agriculture area the clarifier was a habitation and an agriculture area the water distribution point was a habitation area (2) the average of turbidity was 3.12 NTU , the average of temperature was 26.3 Celsius , the average of suspended sediment was 0.012 mg/L , the average of acidity and alkalinity was 7.10 and the average of an electric conductivity was 31.1 µs/cm. (3) the turbidity at the clarifier point was higher than the standard one (4) the turbidity related to the temperature and suspended sediment (p-value 0.05) however, it was irrelevant to acidity-alkalinity and electric conductivity (5) at some points of water distribution system were out of order or damage which needed to be solved. The tap water was quite turbid during heavy rain and there was silt coming down to water intake. The management process of mountain tap water system were to set up a group of tap water users and also to educate people of how to use it properly as well as to maintain it wisely. With the results of studies can be used to prevent the low quality of water sources and also can be brought to improve the quality indicators of people in village. Moreover, it brought up to the local organization to be ready to monitor the quality of water.
