998名“水管家”上岗守护密云水库

为改善水环境,保障水安全,密云区、镇、村三级共344名河长走马上任,同时各村还设了654名管水员,对该区63条河道实行分级分段管理,密云水库有了998名“水管家”。

水库上游白河段全封闭

密云区石城镇贾峪村,是有名的民俗旅游村,全村共有36户精品民宿,最大的特色就是村前的白河。因临近清凉谷景区,河道走势平坦,水流平缓,每到周末,河边挤满了烧烤、垂钓的游客。“就这一小块空地,最多的时候能挤下1000多人。”村支部书记、河段长郭玉春指着一块不大的空地说。

村民瞅准商机,买来几百条橡皮筏,开发漂流项目。“以前一到周末特别火,中午来都找不着房。”村民说。但随之而来的,就是遍地的垃圾和污水。游客前脚一走,紧跟着保洁员就能清出两大车垃圾。

“以前大家只提一级水源保护区,但水库上游的几条河,如果治不好,那还是白搭。”据郭玉春介绍,贾峪村的河道属于三级水源保护区。但为了让汇入密云水库的每一条河流都保持良好水质,今年7月,密云水库上游的白河段河道开始实行全封闭管理,各类漂流项目被全部取缔,包含贾峪村在内的16个入口竖起了大门,挂锁,无论是游客还是附近的村民,都不能再靠近河边,河道内重新变得清澈透亮。

最严格“河长”制度

密云水库白河段封闭后,监督巡查的职责就落在了村里的管水员身上,64位村民,担起了水库上游的白河18公里这一段的巡查任务,看到有游客偷入,或烧烤宿营的,立刻上前劝阻举报。贾峪村69岁的村民王稳海积极响应:“我们这儿景好、水好、环境好,大家都知道要保护密云水库”。

不仅如此,管理的标准也更加严格。密云区域内共有大小河流63条,其中白河、潮河、清水河等主干河流都将汇入密云水库。除了区、镇、村三级河长之外,还引入64名镇级河长助理以及654名村级管水员,该区“水管家”队伍扩充到998人,对全区63条河道实行分级分段管理,构建了较为完善的网格化管理体系。

随着蓄水量的节节攀升,密云水库日渐饱满。近日,密云更是出台了最为严格的河长制,将原本市里提出的“五无”标准翻倍,升级为“十无”标准,在原本的“垃圾、水面漂浮物、污水直排、水体恶臭和违建”五方面问题之外,又将网格化管理体系无缝隙无死角、断面考核机制无遗漏、河道管理范围无规模养殖场、无盗采盗运现象、无新增地下水超采区也纳入进来。

水质监测增频次

“以前提起密云水库,关注点都在水量,现在水量上来了,老百姓更关心水质。”密云水库管理处水环境监测分中心主任潘轲旻说。原本全年12次的水质监测任务,因为水量增长且正值汛期,频次加密到1周1次。

监测水质是通过化学检验评价水质状况的过程,水质检测员每周到白河主坝、潮河主坝、恒河等45个站点取样,通过化验总磷、总氮、酸碱度等43个项目如实反映水库水体情况。45个监测点涵盖密云水库流域内主要入库干支流、库区及出库水体,潘轲旻介绍,水质监测1周1次,一旦发现问题,能够马上做出应急反应,且所有监测数据都要提交到北京水环境监测中心,与南水北调办公室的数据做比对,如果有出入,会再次启动监测并及时处理,确保密云水库的饮用水安全。“不能让水质不合格的水流进密云水库,也不能让‘大水盆’中的饮用水受到污染,更不能让不合格的水流进北京市民家里。”密集监测之下,密云水库水质一直保持优于地表水二类标准。
