Excerpt: ‘Du’a’ – Water research center’ is an architecture thesis by Mohamed Gamal Sabry from the Department of Architecture – Faculty of Engineering – Cairo University that addresses and offers unique solutions for Egypt‘s pressing water scarcity issue through a harmonious fusion of architecture and technology. The goal of this project is to construct a research centre that can increase wind speed using the venturi effect and collect water through fog in Al-Tarfa Village, Saint Catherine.
Introduction: Since Egypt has been experiencing a severe water shortage crisis lately, it is crucial to identify new water sources in the desert rather than the Nile. The goal of this project is to construct a research centre that can increase wind speed using the venturi effect and collect water through fog in Al-Tarfa Village, Saint Catherine. The project aims to generate electricity from kinetic energy and raise community awareness of this technology through this structure.
Egypt has been dealing with a great challenge in water sources lately. About 95% of its people are dependent on certain kilometres of the river Nile. Despite this, UNICEF claims that Egypt is under the global water poverty line due to the rising Nahda Dam, placing Egypt in grave danger.
Firstly, it’s important to know where in Egypt fog can be found. Three locations can be seen on the map. North Coast, Alba Mountains, and Delta Saint Catherine in Sinai Desert. Saint Catherine was the selected site for intervention. As Sinai residents live behind the mountains, the project takes place on the other side.
Final Outcome
Through the use of CFD path simulations to the terrain site, the fog collectors are oriented to optimise wind flow. The structure is then raised to implement the same idea vertically, covering 15,000 residents of Sinai and ensuring their food security by expanding underground water tank suppliers.
In order to collect more droplets, the form generation relies on increasing wind speed through the venturi effect to 5 m/s. This kinetic energy is converted to electricity by the water movement through fog collector towers, lowering the building’s carbon footprint. The community can easily replace and maintain these towers at any time, and the research centre raises community awareness of technology.
Certain types of fog cannot always be harvested due to factors like humidity, wind direction, and speed. Throughout the design process, only the prior parameters are applied. Egypt hardly ever experiences dense fog suitable for harvesting, and slow wind speeds on the ground complicate matters further. However, with certain adjustments, it might be feasible. The numerical equations of the basking beetle’s fog-catching behaviour are the basis for the design simulations, which increase wind speed to achieve the optimum status of fog collection.
Based on the current prices of fog collectors, the numerical feasibility calculations assume that the collectors are operating at maximum efficiency, providing the village water at 210,000 E.P. per cubic metre, which is 10% less expensive and 10% cleaner than the water desalination solutions currently in use in Egypt.
Conclusion: The project addresses and offers unique solutions for Egypt’s pressing water scarcity issue through a harmonious fusion of architecture and technology. In addition to providing a solution, the proposed research centre educates the local community about the technology.
