Drinking water and electricity services are critical to the development of Oman. The Public Authority for Electricity and Water(Diam) provides high quality sustainable and reliable potable water and power services to all people in the Sultanate of Oman.

The Public Authority for Electricity and Water(Diam) is a governmental institution founded on 9th of September 2007 by Royal Decree No. (92/2007), under the requisites of two royal decrees, nos. (58/2009) and (59/2009) issued on October 11, 2009. Diam - The Public Authority for Electricity and Water is the regulator for the water sector in Oman. In contrast to the water sector, Diam's role in the electricity sector is limited to policy overview.
