Determining The Optimal Method For Water Management Using Hierarchy Analysis (AHP):A Case Study In The City Of Baghdad

Abstract

This research aims to determine the most effective method for water management in the city of Baghdad, by using the hierarchy analysis model (Analytic Hierarchy Process (AHP) This model is considered a scientific tool that supports multi-criteria decision-making in a complex environment facing increasing water challenges, such as the case of the city of Baghdad, which suffers from several challenges, including:Scarcity of resources, deteriorating water quality, and institutional and administrative problemsThe model was developed based on a set of technical and institutional criteria, including: water pricing, water awareness and education, water legislation and laws, water loss, water regulations and standards, intermittent water supplies, and graywater reuse.Three main alternatives have been identified to achieve optimal water management: rationalization of water use, water privatization, and activating water investment.

Data were collected using binary comparison matrices distributed to experts in water-related institutions in Baghdad. The results showed that (rationalization of water use) received the highest priority (6092.88), indicating its effectiveness as a first strategic option for addressing problems of consumption and waste. The model also proved its accuracy through an acceptable consistency rate of (5.59%). 

The study recommends the integration of regulatory, awareness-raising, and economic tools to ensure water resource sustainability. It also suggests the potential application of the model to other cities facing similar conditions.
