美国城市更新水系统 以对抗野火 仿照旧金山的模型 American cities update water systems to combat wildfires, mirroring San Francisco's model.

随着气候变化导致的野火加剧,美国城市正与在火灾期间失灵的过时供水系统挣扎。 As wildfires intensify due to climate change, American cities are struggling with outdated water systems that fail during fires. 解决办法包括安装远程封闭阀门和直升机水利剂,现场储存消防用水,以及建造专用的高压水管。 Solutions include installing remote shutoff valves and heli-hydrants, storing water on-site for firefighting, and building dedicated high-pressure water lines. 旧金山的系统包括专门的坦克和水龙头,作为一种模式,但许多社区的实施费用很高。 San Francisco's system, which includes dedicated tanks and hydrants, serves as a model, but implementation costs are high for many communities.
