水智慧城市正在增加灌溉和喷雾的使用，以应对极端炎热和干旱。这是通过广泛使用雨水箱、雨水收集和储存系统以及回收污水来灌溉行道树以及私人和公共绿地而实现的。这些替代水资源为城市提供了新的选择，使其能够在极端的夏季热浪条件下更好地承受和发挥作用，而对饮用水供应影响很小或没有影响。通过蒸发冷却城市动物、植被栖息地和人类的小规模方法正在取得初步成功。然而，需要持续的测试和建模来了解扩大这些干预措施的影响并评估其成本效益。我们描述了澳大利亚城市当前在灌溉方面的创新，以帮助经历类似气候和夏季热浪的其他国家和城市的政策制定。
Water smart cities are increasing their use of irrigation and misting to cope with extreme heat and drought. This is being enabled by widespread use of rainwater tanks, stormwater capture and storage systems, and recycled sewage wastewater to irrigate street trees as well as private and public green spaces. These alternative water resources provide new options for cities to better withstand and function under extreme summer heatwave conditions with little or no impact on drinking water supplies. Small‐scale approaches to evaporatively cool urban animals, vegetation habitat, and people are showing initial success. However, ongoing testing and modeling are needed to understand the impacts of scaling up these interventions and to evaluate their cost‐effectiveness. We describe current innovations in irrigation of Australian cities to help policy development in other countries and cities experiencing similar climates with episodic summer heatwaves.
