This research deals with the adequacy and quality of drinking water in the city of Zagazig when it reaches the consumer through the objective approach, and because clean water is a resource on which the lives and health of the population depend, providing them with it safely and at the lowest cost is one of the most important goals that It is based on the search, The study was carried out by analyzing the spatial relationships between the distribution of the drinking water network and the production stations in Zagazig and between the other elements of population density, slums, building heights, and sanitation. Each of the building heights and the random growth in Zagazig city had a great impact on the quality and efficiency of delivering drinking water to the city’s residents. The economics of production, and consumption were also studied, to reach an optimal spatial organization of the drinking water facility in the city. The subjects of the study were as follows: First: sources of raw water for the city of Zagazig Second: the development of the water network and the urban expansion in the city Third: spatial analysis of the components of the drinking water distribution network (stations - pipes - tanks) Fourth: The loss of drinking water. Fifthly: Drinking water production. Sixth: Average per capita share of drinking water. Seventh: Consumption of drinking water. Eighth: Service Quality Indicators. Ninth: the economics of drinking water production. Tenth: Slums, building heights, and drinking water distribution quality. Eleventh: sanitation.. The study proved that the city needs to be strengthened with additional capacities of stations and networks, and that there are international experiences in network management that can be used and applied in the development of the facility, especially in high-reservoir management systems.
