Water is important for life on earth.
Studies have proven that there is a fixed amount of water on the surface of the earth , but they differ from the distribution area from one place to another and for this reason we must used the amount and allowed us to exploit various ways of doing things our lives.
But in my country Palestine and because what we face by all forms of exploitation by Israel Occupation and the aim of this project is to design a safe network water which is valid for domestic use in Jbarah Village because it locate inside the wall of barrier and neglected by some of the authorities .
We use in this project WaterCad as a software to determine the demand on every junction we have .
From the tables shown in next chapter we note that the Pressure on the node between bars in the lowest point and bars as maximum value is within the range and we use the Minimum diameter for design is 2 inches in general and this size satisfy over have diameters in the net work, this indicate the network mostly commercial also from pipe table we note that the Velocity ranges from 0.2m/sec to 2m/sec in average , and this value between the rang of constraint velocity.
We conclude in this project that if we increase the diameter of the pipe, the velocity will decrease. Also if the head of the pump increase the pressure will increase
We advice to choose the loop system with EPS because its flow and velocity was higher than the other networks and its pressure was the lowest one and this led to that the pump has lowest power , lowest electricity and lowest money
We recommended going ahead with this project as soon as possible since this village suffers from the sewer problems and suffering from the lack of water, so this village really need to it. Also we can make combined system ( wastewater and storm water ) but we choose this system because of small area and the slop of this area make two separate system more easily .
