Estimation of the Per Capita of Drinking Water Consumption; A Case Study of Ardekan City, Yazd Province

Enforcement of policies related to water consumption management necessitates the evaluation of a variety of strategies leading to increased water productivity. One of these strategies is the separation of drinking water distribution from other uses. In this regard, the per capita of drinking water consumption plays a major role in the design of systems for drinking water supply and distribution. However, it seems that few studies have been conducted on the estimation of this amount in Iran. Therefore, the numbers and statistics cited in the references and technical reports are either dependent on standards (IRI MPORG Publication No. 3-117) or extracted from other studies in similar countries in terms of climate and culture. The present study aimed to estimate the per capita consumption of drinking water in Ardakan, Yazd Province, through field studies and a survey of subscribers who collect their required drinking water from public water distributors. For this purpose, the research background at the international level was reviewed and then a statistical methodology was developed and implemented for the survey and field studies. Finally, the data were statistically analyzed and the per capita consumption of drinking water in this area was determined.
