Water scarcity and unequal geographic distribution of this important resource may be one of the most important environmental challenges affecting the sustainability of water resources. Especially, where water resources are scarce and the rate of its withdrawal is higher than the rate of replenishment through the hydrological cycle.There is a definite risk of depletion, leading to unsustainable use of water resources. Therefore the decoupling of water resources from economic growth is the key of sustainable development, especially for Egypt,in light of the current problems that have become increasingly complicated regarding to water resources.Decoupling refers to the economy's ability to grow without a corresponding increase in environmental pressure. This means, decoupling Natural Resource Use and Environmental Impacts from Economic Growth.This paper provides an overview of how decoupling policies contribute to the water sector. Through a number of interviews done with water resources'experts who emphasize the necessity of using these new policies when managing water resources. The paper also describes some technological solutions that can contribute to the implementation of water decoupling policy in the agricultural, industrial and municipal sectors. It also provides some achievements of some countries regarding the decoupling of water resources and economic this policyisconsidering one of the components of the integrated approach that can be used in water resources management in Egypt.
