The new residential area is exposed to have 25000 residences, three schools to serve 1000 students, and a Plaza Markt that can serve 2000 persons. The water will be supplied from a purification station installed on the Tigris River at an elevation equal to 130 m. The distance between the water purification station and the center of the new residential area is about 9.5 km, and the elevation of the city center is about 150 m. The required pressure in the new residential area center is 30 m. The available pipes in the market with their price are shown in Table 1. Also, the price for each 10-meter of pump head is 1500$.
