Household income is one of the most determinant factors of individuals’ living standard in general and consumption in particular. According to Table 4.3, out of the total sample households 13(8.8%) earns less than 600 Birr per month, 17 (11.6%) of the respondents monthly income was 601-1200 birr, 22(15.0%) earn about 1201-1800 birr per month, 24(16.3%) earn about 1801-2400 birr per month, majority of the respondents 44 (29.9%) monthly income that they earn from their current job was 2401-3000 birr, 27 (18.4%) of the respondents monthly income was ;3000 birr. As the survey result shows that from the limited amount of monthly income, expenditure on basic necessities like food, cloth and other social services take greater
Regarding the occupation of the sample households in the study area were diverse employment backgrounds. The greater part of the respondents was engaged in employee and commercial/trade 51 (34.7%) and 39(26.5%) respectively, 18 (12.2%) daily laborer. Farming and others were 25 (17%) and 14 (9.5) respectively. In addition, the income basis are both agriculture and daily labor this varieties resulted the water supply situation inferior as further suggestion collected by instigator from sampled respondents.

4.2.1 Access to water supply and Status of provision
As stated by WHO, basic access can be defined as the availability of water at least 25 liters per day per person, a distance of not more than 1 km from the source to the house and the maximum time taken to complete round trip should not be more than 30 minutes. The UNDP (2008) stated the minimum absolute daily water need per person per day is 50 liters (13.2 gallons) which include: 5 liters for drinking, 20 for sanitation and hygiene, 15 for bathing and 10 for preparing food. However, because of lack of water supply, millions of people try to exist on 10 liters (2.6 gallons) a day (ADF, 2005). In densely populated areas, a water transportation trip of 30 minutes or less, including get in line time was a more appropriate indicator of access. So, inadequate access of water supply and distribution in the study area related with different type of problems that again influence demand of water as shown the next table.
