Abstract:
The project is named Nyala Water Project, the design capacity of this project is
40,000 cubic meters of water per day , it was designed by the Public Water
Corporation of the Ministry of Irrigation and Water Resources in November of the
year 2000, and that the proposal is based to drill 20 wells in the area of Gareida
assuming that the productivity of these wells are equal and equal to 2,000 cubic
meters per day , and that the water is disinfected with chlorine according to World
Health Organization standards (WHO). And then will be pumped by a number of
pumping stations to the city of Nyala, a distance of 85 kilometers in the north.
Since the basic design of the project (hydraulic design) is based on pumping water
through the pumping stages, the first in the field, and the second after 26
kilometers, and the third a distance of 18 kilometers from the second and fourth 28
kilometers of the third and discharges water into two tanks with a capacity of 4000
Cubic meters each, and then to the distribution network of the city. After reviewing
the existing design work and analysis of the basic components of the project, it was
found that the project can be re- designed to reduce the number of pumping
stations, thus reducing operating and maintenance costs. Steps have been clarified
in the new hydraulic design in chapter four, as well as the work tables to compare
the operating costs in the case of the old and the new situation. And also found that
the operation of this project by electricity can reduce costs of operation and
maintenance to a very large, and the research has made the comparison between
them and the old design, and also between them and the new design.
