Date collected by referring to the different parts of rural water and waste water company of Kermanshah Province and checklist were completed. The study showed the volume of produced water and sold water has increased and the water loss percentage has decreased. High cost of water production compared to revenue of sold water and water loss resulted in significant detriments in terms of the water production costs. Water loss level decreased from 33% to 30% as result of measures taken to reduce water loss but, it is still15% higher than the world average level. Also the reduction in number of water resources and increase in the number and volume of reservoirs indicates a lack of water and a growing need. As result of high water loss, waste of costs in the contrast of water production cost and also because physical water loss accounts for most of the water loss of villages, necessary measures can be effective in reducing loss and have economic justification.展开更多

This descriptive-analytic study was done by component questionnaire and its sustainability and validity have been verified. The sample size of the statistical population of Kermanshah was selected as 400 people while it was considered that the population of the city was approximately 1 million people. The results showed that 77% of the participants in the study suffered from respiratory problems when the haze occurred. A total of 85.5% of the respondents in the present study believed that the precipitation rate had a direct effect to reduce haze. Also, 85% of the people with heart disorder had health problems during the haze. 63.3% of all participants had to use medical services when the haze occurred. However, 77.3% of participants were unaware of the necessary actions of the authorities when the haze occurred. Most of the studied people acknowledged that they obtained information about the negative effects of dust storms and the methods of reducing the effects to their health through broadcasting.展开更多
