上海雨水利用逐渐起步 城市雨水利用逐步推进

目前,地球上的淡水资源越来越短缺,在针对这样的现状,人们开始寻找新的水资源途径,而雨水利用就是其中最为重要的一种。近些年来,上海市已经开始逐步重视雨水资源的利用,如果上海市每年能将约24亿吨的雨水利用起来,就可以完全满足全上海人的用水需求,缓解上海市水资源短缺问题。

在上海浦东注明的孙桥现代农业园区,人们将6万平方米的大棚顶盖的雨水“开发”起来,将每座大棚的排水侧沟都连结起来,通向四座大型蓄水池。这些长为60米,宽慰25米,池深3米的蓄水池可以储存近3000立方米的雨水。在经过沉淀、过滤之后,可以将这些雨水用于农业园区的浇灌作业。

除了在农业方面可以进行雨水的再利用外,在路面和广场等地也大力推广了渗水材料和结构,让大部分地面的雨水径流成为回灌水源;此外,在高架两侧地下建设很多蓄水池,使沿着高架流下的雨水可以就地进行“回用”,这些雨水可以养育高架旁的花草,也可以在干旱时期作为浇灌储备用水。而针对小区等地来说,可以根据实际情况建设蓄水系统,利用蓄积的雨水来冲地,洗车等一系列工作。


水是生命之源。多少年来流失的雨水,在发展循环经济、建设节约型城市的全新理念指导下,今后不会再被浪费,而会受到上海人的善待,为我们的现代城市作出更大贡献。
