Establishment of a company called Water and Power Engineering Services (Mahab) was first proposed to the parliament by the Ministry of Water and Electricity. Articles of association of this company were passed by the parliament in late 1964 and the company commenced its activity legally on 19 March, 1969. The company's activities included providing technical consulting services and preparation of designs of dam construction, irrigation and drainage networks, water well drilling and aqueduct construction, power production, transmission and distribution, supervision on construction of the said projects and implementation of laboratory services. In late June 1980, in order to provide specialized activities, water and power sectors of Mahab Company was separated from each other and its power sector was renamed Moshanir Power Engineering Consultants. The aim of the company was initially to provide technical and engineering services in the areas of electric industry. But gradually with the increase of national needs, Moshanir's activities expanded to all areas of water and energy, and at the present time it offers services in all infrastructure and development fields. In addition, Moshanir's services have gone beyond national borders and have strong presence in regional and international arenas. Now Moshanir is a leading brand in the area of its activities and is synonymous with quality, speed and diversity in the provision of services.
