Dubai Electricity and Water Authority (DEWA) was formed on 1 January, 1992, by a decree issued by the late Sheikh Maktoum bin Rashid Al Maktoum to merge Dubai Electricity Company and Dubai Water Department, which had been operating independently before then. Both organisations were established by the late Sheikh Rashid bin Saeed Al Maktoum in 1959. Dubai Government fully supported the Electricity Company and the Water Department to provide Dubai’s citizens and residents with a continuous and reliable supply of electricity and water. Since then, DEWA has made considerable achievements, to be ranked as one of the best utilities in the world. DEWA provides services today to more than 780,000 customers with a happiness rate that reached 95% in 2016.
