A brief description of when and why the water use baseline was adopted:

Cairo University received a Japanese delegation from Nagoya and Kyoto Universities, to discuss the mechanisms for implementing the joint applied research project presented by Cairo University to treat wastewater and generate biofuel energy from human and agricultural waste within the framework of localizing decentralized tertiary treatment technology in Egypt.
Wastewater of CU collected from different campus zone is treated according to standard and polices of environment ministry. The treated water is used for watering plants and gardens in the public areas of the university.

A brief description of the institution's water-related behavior change initiatives:

A brief description of the institution's water recovery and reuse initiatives:

Dr. Mohamed Othman Elkhosht, President of Cairo University, directed the necessity of submitting research proposals for applications related to solving national problems, benefiting from distinguished international experiences in the field of applied research, and supporting cooperation between Cairo University and universities and scientific institutions abroad in applied research projects of interest to the state, including a treatment project. Wastewater and biofuel generation in cooperation with Japanese expertise.
Also many professors inside CU are involved in mega-projects held by government in wastewater treatment for example: New Cairo Wastewater Treatment Plant - Water Technology, Bahr El Baqar: Egypt’s record-breaking wastewater treatment facility.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

The primary source of freshwater for Cairo University is River Nile since it provides a consistent supply of the water we need to survive each day. The River Nile is the source of the water used for drinking and daily purposes only. After treatment process of freshwater from Nile river in the Giza water station to produce safe, superior drinking water, the water is then piped throughout the city to the university.
Techniques for rationalizing water use on campus.
- The installation of a new drinking and fire water network, where the water pressures are controlled) to suit the application, is ongoing.

- Cairo University is holding a plan for all buildings to have a separated sewerage system, for waste water and for clean water (rainwater).
- New pipeline system is also under-construction for collectting water from the roofs of the buildings and is then discharged into tanks.
- Work to rationalize water consumption
- The faculties were asked to take the necessary steps toward rationalization by hastening the repair of damaged sanitary equipment and creating posters to inform the university's affiliates, including students, administrators, and faculty members, on the value of rationalizing consumption and the prompt reporting of leaks.
- Replacing old taps with newer ones with sensor to reduce waterloss.
- To prevent waste from water pipe leaks, a follow-up committee was established to check in on the various universities twice a month to see if there are any issues.
- Plans and procedures for maintaining the university's internal supply networks and faucets to stop water wasting.
- Water-saving cutting technology can be implemented on the nozzles of currently-used faucets without changing those taps at all. It is a contemporary, straightforward, and quick process to disassemble and install. The rationalization axis, one of the most significant axes of the plan for the development and management of water resources, is achieved by flowing water.
- Using spray manifolds to replace pipes with drilled holes.
- The workers make sure the nozzles are positioned correctly to guarantee exact spray coverage with the least amount of waste.
- Installing in-line strainers on all spray heads and routinely checking nozzles for wear and clogging.

- Cairo University has long tended to plant drought-tolerant plants like palms (date palms and prichardia) and trees (conocarpus, tamarind, prosops, Broad pepper, Ficus netda, glass mattress, carob, cypress, lemon cypress, thin pepper, decrostaches, sycamore, bell, etc.) because of the problem of water scarcity and the university's belief in its significant role as a key partner to confront.
