Given the environmental conditions governing it, its stakeholders' expectations and its organizational mission and in the context of supplying and distribution of water and safe disposal of wastewater, the water and wastewater sector needs to grow and develop in parallel to the changes in environmental conditions. For this reason identifying the development condition of the water and wastewater sector is a necessity in the context of targeting plans and strategies from the aspect of sectorial management and senior management. This research was undertaken to identify the level of development of the water and wastewater companies (35 companies) from the aspect of the different indicators specific to the water and wastewater industry in the context of clarifying the economic plans and to enhance and improve operational activities. In the course of the study, after identifying 18 indicators, the exploratory factor analysis was undertaken and the number of indicators was reduced to 5 significant factors. Then the combined indicator was calculated according to the weight of factors and the entire sector was classified. In continuation and by applying the hierarchal clustering method the development levels of water and wastewater companies were categorized on the basis of 5 factors in three homogenized groups of development. The study's results indicate an unbalanced and non-homogenous level of development in the sector, with some companies failing to achieve the desirable level of development and needing greater attention and planning to improve the developmental conditions.

In recent years, numerous policy programs such as the construction of dams on surface water resources in upstream areas, rationing of water input in the agricultural sector, installation of meters on groundwater wells and seal of the unauthorized exploitation wells to solve water deficit problems in agricultural sector of Kerman province used. Implementation of these policies on the water supply side have many effects on the cropping pattern and farmers’ gross profit of in south of Kerman province and so it requires proper planning to water resources management and agricultural production in the region. For this purpose, in this study to estimate the economic value of agricultural land and water inputs and then to evaluate the potential impact of water supply policies on the agricultural sector in the south of Kerman province using of the statistical data related to crop years of 1996-1997 and the PMP advanced economic planning model. The results showed that by applying the water supply policies, the cropping pattern leads to the development acreage of low water and grain products and onions, cotton and vegetables experience the greatest reduction in acreage. Under these conditions, Kerman farmers pay about one-third of the economic value of agricultural water in the form of costs of extraction and water transfer. The farmers also receive a price elasticity of water demand of 0/175. The water resources supply polices decrease the total gross margin of cropping pattern 0/92 to 3/46 percentage compared to the base year conditions,
