In 2005, and after the expiration of the management contract between the Water Authority and LEMA Company; a coalition of French, British and Jordanian companies, the Ministry of Water and Irrigation/Water Authority of Jordan conducted an analytical study in cooperation with the donor states and a technical consultancy establishment to identify the best alternatives and available options to manage the water services in the Capital. The study recommended entrusting the management of water and sewage services in the Capital to a national private company with financial and administrative independence operating on commercial basis. The result was the creation of Jordan Water Company, Miyahuna in January 2007 as an independent limited liability company fully owned by the Water Authority of Jordan operating under the private sector laws and regulations to take over the management of the water and sewage services in Amman. The Water Authority granted Miyahuna the right to manage the services in the Capital with full ownership of revenues and additional resources generated from the sewage tax at 3% of the rental value of the real estate properties. In addition, the Water Authority transferred to Miyahuna the complete management of operations, maintenance and investments resulting from the expansion in the provision of water and sewage services in the Capital. Investment responsibilities are clearly defined in the Assignment Agreement allocating responsibilities between Miyahuna which is responsible of investments in network extensions and normal capital maintenance projects and the Water Authority of Jordan that handles the investments of big projects of network rehabilitation and major infrastructure construction needed to keep pace with the accelerated expansions in the Capital.

Since its foundation, Miyahuna was keen to maintain the workers' rights where all employees were transferred from LEMA to Miyahuna in accordance with a salary scale system based on justice and equal opportunities. In addition, the Water Authority of Jordan retired employees were re-hired in accordance with the company's regulations and bylaws and according to a salary scale closer to the private sector.
