No / Adaptive Water Management (AWM) could provide a sustainable route to address the existing complex problems of urban water management such as continued water shortage and flooding through the future. The AWM application could be a new alternative path in water management especially in developing countries which suffer from common weakening features such as unreliable infrastructure and poor institutional organisations. The AWM distinguishing characteristics such as polycentric governance, organisational flexibility and public participation are considered for feasibility study of the AWM implementation. The paper investigates whether AWM could be applied to a developing-country city in order to deal with future uncertainties of water supply/demand. The required data was collected from the water professionals of Tehran Province Water and Wastewater Company (TPWW Company), which is in charge of water supply and management of 12 million people of the Province. The key elements of AWM performance are transformed to a multi criteria decision model of Analytical Hierarchical Process (AHP) in order to facilitate quantification of the influence of corresponding qualitative elements derived from semi-structured interviews held in the Company, and for further analysis of urban water managers' views in a structured way. The research findings show that despite the lack of structural adaptability there are positive attitudes towards inter departmental communication and linking to the external decisive actors such as the Company's consumers. As a generalising result, the AWM concept would be applicable to the similar developing-country cities particularly located in the Middle-East region while simultaneously promoting technical and institutional performances.
