From the responses of the farmers on the satisfaction with water supply for households, it is found that the primary source is public water supply. The Mann-Whitney test is used to analyze the impact of satisfaction with water supply on the WTU and WTP. It is noted from the results that the satisfaction with water supply has a significant influence on the WTU and a highly significant influence on the WTP (Table 3).
