The university buildings are located in an area known for the scarcity of drinking water sources and its source is the water company affiliated with the Ministry of Energy and Water. Accordingly, a special network has been developed that starts from the main line and is distributed over the upper tanks in each building. In addition, all floors are provided with distribution points for drinking water continuously to serve students and university staff.

The total value of the quantity of water used in the Wardanieh campus is estimated at about 4888 m3, distributed between the water use, and its value is estimated at about 3488 m3, of which 2907 m3 originate from rain water and 581 m3 from the wells in the campus. The irrigation water is about 1400 m3.

The university relies at a rate of 20% of the estimated water expenditure, which is equivalent to 581 m3, on the water of the wells in the campus, which are treated for use as drinking water for students and employees at a rate of 70%, equivalent to 407 m3, and the water of the company affiliated to the Ministry of Energy and Water at a rate of 30%, which is equivalent to 174 m3.

Since the first source is not sufficient to serve the university throughout the year, artesian wells have been developed to cover the shortage of drinking water, especially in the summer season, as the consumption rate for each student is at a rate of 15/20 liters per day and it has been verified that it is suitable for use with treatment at a rate of 1ppm using ultraviolet radiation.

The project is equipped by seven ground tanks with a water collection system from the roads. The collected water is used in the irrigation system of the agricultural lands surrounding the project.

Ground tanks (from R1 to R4 in blue color) with total capacity of approximately 2907m³ (Table 1) were built distributed over the entire project. Ceilings were designed diagonally to collect water and deliver it to the tanks separately (Figure 3).

Table 1. Ground tanks

It is collected in lower tanks distributed throughout the project, which work as sedimentation ponds as well. Then the water is drawn into the main upper tank, and from it is drawn into the upper tanks of all buildings after being treated with ultraviolet radiation. The total amount of water reaches 2907 m3 (Figure 5).

The Wardanieh Campus includes the College of Engineering and the College of Business Administration, which accommodates 900 students annually, with the presence of the general library building, the administration building and student services, in addition to the staff and members of the teaching staff estimated at about 250 people.

In the campus, each building has been equipped with separate bathrooms for men and women, as well as equipped with washbasins and the necessary cleaning materials for each wash. The bathrooms were distributed on all floors. A kitchen on each floor is used to serve the Staff. The bathrooms were connected by a network of pipes with manholes reaching the treatment and sedimentation plant.

The rain water is collected in lower tanks distributed throughout the campus. These tanks work as sedimentation ponds as well. Then the water is drawn into the main upper tank, and then to the upper tanks of all buildings after being treated with ultraviolet radiation.

The wastewater from the bathrooms and kitchens is collected by pipes to the sedimentation and treatment basins located at the outskirts of the campus, and after the sedimentation stage, the wastewater is discharged into the public piping network of the Ministry of Works. The waste in sedimentation basins, it is transported periodically throughout the year for treatment outside the compound.

The rainwater that is produced from the roads and landscapes is used in the permanent drip irrigation system to irrigate the trees and plants inside the campus, especially during the summer days.

The architectural maps of the campus were drawn up and all the requirements needed by the project, which have a relationship to the surrounding environment, were developed and studied, including the lack of a source for use and drinking water, and the absence of an infrastructure that would meet the needs of the buildings included in the project. Accordingly, the infrastructure was equipped with the development of four networks as follows:

• An internal network of drinking water that is distributed to all buildings
• A network to collect rainwater from the roofs of buildings
• A rainwater collection network from roads and ground spaces
• A network for Waste water and a treatment station (septic tank)

Each of the project buildings has been equipped with separate bathrooms for men and women, as well as equipped with washbasins and the necessary cleaning materials for each wash. The bathrooms were distributed on all floors (Figure 6).

The efficiency of water use increases greatly by ensuring controlled withdrawal operations by the presence of valves at all exits on the network with constant maintenance of the pipes. The used water network and tanks have also been provided with an automatic control system (Figure 7) to fill the tanks and monitor the daily intake movement.

After completing the study of maps and determining the areas allocated to buildings and thus green spaces, the university administration proceeded to work on afforestation of the areas surrounding the project with cypress, pine and trees that do not require continuous irrigation works. The irrigation system was also introduced to the point on green spaces close to the buildings.

The rainwater that is produced from the roads and landscapes has been used in the permanent drip irrigation system to irrigate the trees and plantings inside the campus, especially during the summer days (Figure 8).

The total volume of water used in the campus during the school year, which includes water use, drinking water, and water used for agriculture is estimated at about 4888 m3, distributed between the water use, and its value is estimated at about 3488 m3, of which 2907 m3 are a source of rain water and 581 m3 as a source from the wells in the campus. The irrigation water is about 1400 m3.

The total volume of water Reused is about 4307 m3as follows:

• Rain water from roofs and balconies: Ground tanks (from R1 to R4) with total capacity of approximately 2907m3 used as a potable water.
• Rain water from the roads: The project is equipped with seven ground tanks with capacity of 1400 m3 used for the irrigation system.

The university has adopted the teaching programs of the College of Engineering, Department of Civil and Surveying Engineering, by setting up special teaching requirements that have to do with water management, irrigation methods, and ways to complete the infrastructure. The university has worked to interact with the surrounding area to convince the parents and students to enroll and participate in the educational process. The following courses related to the water management implemented in the university are:

Roads and other networks /sanitary /hydrology /Hydraulics/ Geology/Irrigation.

The project depends on rain water in the main form as an alternative to the water received from the Ministry of Energy at a rate of 80% of use. Noting that the water of wells is not used except in days of scarcity, allowing the rest of the surrounding areas to benefit from the surplus water available.

The university secures from its sources water for the agricultural areas surrounding the campus, (Figure 9) in agreement and coordination with the municipality and the owners of neighboring properties.

Water resources, such as lakes, rivers and reservoirs, are essential for every community. Water and sanitation is one of the primary issues for public health. The use of rainwater after treatment reduces the need for other resources. The efficiency of water use increases greatly by ensuring controlled withdrawal operations by the presence of valves at all exits on the network with constant maintenance of the pipes.
