本研究评估了在沙特阿拉伯干燥气候条件下家庭雨水收集的潜力。对沙特阿拉伯几个城市可收集的雨水量进行了估计，发现每年可收集的雨水量超过7.5立方米/100立方米。收集雨水的每立方米成本与生产淡化水的每立方米成本进行了比较。人们发现，收集雨水比从可再生能源驱动的海水淡化厂生产的淡化水更便宜，但化石燃料驱动的海水淡化并非如此。该研究还考虑了雨水收集对缓解洪水和减少温室气体排放的影响。对沙特阿拉伯安装屋顶雨水收集系统的成本效益进行了分析。报告显示，在冰雹、吉达、塔伊夫和利雅得等城市收集雨水在经济上是可行的，而在麦加、麦地那和布莱达等圣城则不建议这样做。
This work evaluates the potential for rainwater harvesting at the household level in the dry climate of Saudi Arabia. The amounts of rainwater that can be harvested in several cities in Saudi Arabia were estimated and it was found that a significant volume, exceeding 7.5 m3/100 m2per year, can be harvested. The per cubic meter cost of harvesting rainwater was compared to that of producing desalinated water. It was found that harvested rainwater is cheaper to capture than desalinated water produced from renewable energy-driven desalination plants, but that is not the case for fossil fuel-powered desalination. The study also considered the effects of rainwater harvesting on mitigating floods and reducing greenhouse gas emissions. A cost-benefit analysis of installing rooftop rainwater harvesting systems in Saudi Arabia was performed. It revealed that it is economically feasible to harvest rain in cities including Hail, Jeddah, Taif, and Riyadh, while it is not recommended in the holy cities of Makkah, Medina, and Buraidah.
