Water Supply Expansion for Metropolitan Ankara

Abstract

Problems of managing urban water infrastructure for a rapidly expanding metropolis are demonstrated in the case example of Ankara. There has been a severe shortage of water (about 20% of the demand) in the last 20 year period in Ankara although a master plan was prepared and various facilities were added to the system. The difficulties of projecting the population growth and water demand per capita are emphasized. The failure to provide enough water is due to the problems of financing the new supply and distribution systems, and the organizational conflicts between the two agencies responsible for the construction and operation. Recently the expansion of the system to satisfy requirements until the year 2030 has been investigated by a systems approach as a part of a NATO Science for Stability research project. Dependable yield and optimal reservoir operating policies for various stages of the expansion project have been studied on a mathematical model of the system by a new algorithm based on dynamic programming.
