Description

清晨,在湖南长沙尖山印象公租房小区门前的取水阀前,一辆环卫车正在取水。与普通取水阀不同的是,它旁边立有一块专属取水口“名片”。

这是长沙高新区市政园林环卫有限公司的专用取水口,水源来自收集在地下的雨水,水质可用于绿化保护、道路浇灌,且价格要比城市自来水低20%。该企业所用水源,正是中国首宗雨水水权交易的水资产。

2020年底,中国首宗雨水交易在长沙顺利成交。湖南雨创环保工程有限公司以每立方米0.7元的价格,购买了湖南高新物业有限公司集蓄在尖山印象公租房地下的雨水资源使用权,再以每立方米3.85元的价格转让给长沙高新区市政园林环卫有限公司。近日,中国水权交易所颁发了中国首宗城市雨水水权交易鉴证书。

近年来,长沙积极探索建设海绵城市,已累计建设雨水收集利用工程500余处,建成7万多立方米的雨水综合利用系统。此前,由于缺乏雨水资源利用刚性政策措施等因素,长沙的雨水资源利用率较低,部分存蓄在地下的雨水变成黑臭水体等新污染源。

据悉,目前中国各地的环卫、绿化等用水大多是和饮用水同级别的自来水,但非生活类用水很多时候可用雨水替代。对此,湖南雨创环保工程有限公司董事长曾福安表示,公司研发了雨水蓄水模块及处理技术,将绿地、屋面及地面的雨水汇总后,要经过截污挂篮、弃流过滤、雨水过滤和消毒等技术环节。处理完的雨水水质能达到国家杂用水甚至饮用水的标准。

作为中国海绵城市早期发起人之一,刘波还建议,湖南可以成立地方区域性水权交易机构,把洞庭湖及湘江水系的水资源管理起来,用雨水资源的资产化和水权交易促进雨水产业发展,为“绿水青山变金山银山”建立起自然资源资产市场交易和投融资通道。
