King Abdulaziz University has established clear standards and guidelines for water discharge and treatment within the campus to preserve water quality, protect ecosystems, and safeguard public health. This is achieved through the implementation of an integrated wastewater treatment system and the adoption of the latest treatment technologies in accordance with international standards.
The Water Research Center and the General Administration of Facilities are the entities responsible for managing water treatment and discharge operations. They conduct regular water quality tests in line with environmental standards to ensure that all discharges remain within environmentally permissible limits.
Department of Water Resources
Sanitary Drainage Network:
A comprehensive sewage network serves the entire university, including faculty housing, student and nurse dormitories, medical centers, the female campus, the main university campus, the academic square, and the preparatory year area. Wastewater Treatment and Storage: Wastewater is conveyed through the sewage pipelines to the central treatment plant located within the university campus for treatment. The treated water is then stored in main reservoirs belonging to the treatment plant. Irrigation Pumping Station: A dedicated pumping station supplies irrigation water to all green areas within the campus .
The University has developed internal standards aligned with the regulations of the Ministry of Environment, Water and Agriculture and the Saudi Standards, Metrology and Quality Organization (SASO) to regulate the discharge of treated water and ensure that it does not harm aquatic or groundwater ecosystems.
Three wastewater treatment plants have been established on campus using membrane bioreactor (MBR) and reverse osmosis (RO) technology to permanently improve water quality before discharge or reuse for irrigation or cooling purposes.
The stations separate rainwater, groundwater, and contaminated water from the sewage system to prevent pollution and ensure safe and environmentally compliant discharge.
The Water Research and Facilities Management Center conducts regular water quality tests according to environmental standards to ensure all discharges remain within permissible environmental limits.
The treated water is used to irrigate green spaces and agricultural areas within the campus, reducing reliance on fresh water by only 10%-15% from the national water company.
Water Recycling Program (King Abdulaziz University, Saudi Arabia)
Water Pollution Group
Water pollution group is interested in studying different water pollutants, factors that affecting them, and propose appropriate solutions. In addition to acquiring knowledge and exchanging experiences through distinguished scientific researches and specialized training courses. The group depends in its work on a team of experts in water treatment, and a group of distinguished scholars from inside and outside the kingdom, as well as international collaborations with the world's best international universities, In coordination with the Deanship of Scientific Research .
Research Priorities
Integrated research projects are encouraged to focus research on one or more of the following areas:
Organic and inorganic pollutants in different water matrices.
Wastewater generation, sources, characteristics, distribution, impact and related applicable reduction and treatment programs.
Wastewater treatment reuse/ recycling using biological, physical and/or chemical technologies.
Technologies suitable for removing heavy metals and hydrocarbons from industrial wastewaters.
Physic-chemical and/or biological technologies for nutrient-rich (phosphorous and nitrogen) wastewaters treatment.
Sludge treatment technologies and reuse.

6. Setting priorities for the finance and implementation of scientific projects submitted to CEES according to the strategic plan.
Activities
1. Establishing a permanent research group of equal opportunities experts and includes foreign and local experiences.
2. Developing research priorities for the unit aligning with CEES strategic plan.
3. Suggestion some training courses that can be carried out by the unit.
4. Creating a list of necessary equipment for water pollution lab.
Water Conservation Program Implementation
The university has opted for the Policy Formulation, Implementation Plan, and the University's energy conservation guidelines.
Water Management Project by controlling weed around the surrounding areas which helps to balance the water conservation.
Domestic water conservation potential
The impacts of conservation measures such as the installation of water-saving devices, water metering and pricing schemes, water rationing and public awareness programs, strict plumbing codes, penalties for wasting water, programs designed to reduce leakage from public water lines and within the home, water-efficient landscaping, economic and ethical incentives are addressed in detail. Cost savings in arid climates, with particular reference to Saudi Arabia, in relation to some conservation techniques, are presented. Water conservation technology and tentative demonstration and implementation of water conservation programs are discussed.
Domestic water conservation potential in Saudi Arabia
The effectiveness of urban water conservation and desalination for water resources management in Jeddah city
This paper investigates the effectiveness of existing desalination water demand alternatives in Jeddah water developments using the Water Assessment and Planning (WEAP) model. Analysis of trends in water supply and demand between 2017 and 2030 is considered. In addition, the vulnerability analysis of the water supply system is examined after identifying years of unmet demand. The results of the model show that Jeddah will have a shortage of 504 MCM in 2030 if the existing water supply remains the same. Introducing water conservancy and leak reduction measures in existing desalination reduced unmet demands by 66 and 21% respectively.
Sewage Disposal
King Abdulaziz University recognizes the importance of wastewater management, water quality improvement by healing process, then recycled in some activities such as flower watering. Also, reduces pollution of the water before draining into the environment.
Constructed wetland system is more popular method for wastewater treatment in Thailand. Due to high efficiency treatment of organic matter, nitrogen, phosphorus, suspended solids and heavy metals in the water. In addition, there is also a low cost of construction. The operation and maintenance of the system depends on natural processes combined with growing plants in wetland. This is an important part of environment conservation and biodiversity promotion.
Aerated lagoon is a wastewater treatment system that uses oxygen from the aerator, to add enough oxygen into the water. Microorganisms can be used to decompose organic matter in wastewater faster than decomposing it naturally. Aeration pond system can effectively treat wastewater, based on the principle of microorganisms under oxygen conditions. The aerator additionally adds oxygen to the water, also stirred the water in the pond. This method decomposes organic matter throughout the pond.
Wastewater from buildings, no matter if they are near or far from water resources, when released without treatment affects water quality. Therefore, the natural water resource is degraded and cannot be useful for its use. Installing septic tanks and grease traps will prevent contamination of building wastewater. This is a simple technology for treating wastewater and is also a suitable method to reduce water pollution. Since, the grease of the kitchen utensils will be trapped and will not mix with the sewage in the drains.
