Iran, is one of the countries located in a dry and semi-dry area. Many provinces are facing water scarcity. This is not only due to the low rates of precipitation received, but also because of the increase in demand on water resources for municipal, agricultural and industrial uses. For reduction of water consumption, many research works have been carried out. Wastewater reuse has proven to be effective and successful in creating a new reliable water supply. The present study aim to propose an overview on the water productivity and wastewater minimization in industries which consumes a great amount of water in different units. In this paper some industries were chosen to measure the possibilities of decrease in water consumption and reduction in wastewater production. The management system implemented in the companies resulted in up to 50% save in water in addition to reduction in materials used for the production. Recover of useful materials from the wastewater, recycle and reuse of wastewater in the plant and overall of large amount of wastewater which was minimized have been resulted in the companies. At the end, some suggestions have been given for implementing the water and wastewater minimization plan in the companies.
