Data were collected<br>by means of a questionnaire at 12 separate locations from altogether 305<br>individuals. Common descriptive statistics were applied for this research. The water<br>quality at the site of investigation was tested against standard procedures. It was<br>found that the staff taking care of the water supply system worked on time but not<br>always according to the rule. Funds for the water supply management system were<br>insufficient. At only 4 places (33.33%) standard criteria for the water quality was<br>sufficient. However the physical quality of every water sample passed the standard<br>criteria. As far as the chemical content of the water was concerned at 4 locations<br>(33.33%) the iron content and other chemical substances were found to be too high.<br>The lead concentration was not according to standard at various measuring points.<br>Samples from 25% of all of the sites tested were contaminated with coliform<br>bacteria and fecal coliform bacteria above the standard. The level of satisfaction of<br>people using the water was neither very good nor very bad for 51.80% who were<br>asked. Overall satisfied had been 41% and not satisfied at all were 7.20%. Extra<br>training should be provided for the staff and the administration committees<br>responsible for the water supply system.
