A | 清晨5点，滨江区西兴路还沉浸在微凉晨色中。洒水车司机冯水良拧开阀门，细密水雾均匀覆在柏油路上，既湿润了空气，也压下了扬尘。和往常不同的是，这一车“解渴水”并非取自自来水管网，而是来自几百米外的建设河——经净化处理后，它成了环卫作业的“第二水源”。这是杭州推进环卫用水“换血”的日常缩影。今年以来，杭州持续调整环卫作业用水结构，用河道净化水、再生水替代自来水，把水资源节约集约利用落到每辆环卫车上。市城管部门的最新数据显示：今年上半年，全市环卫作业总用水量达507万吨，其中河道取水160万吨、再生水取水70万吨，“第二水源”合计占比45.37%。“以前装一车水，用的都是自来水。
B | 去年12月滨江新增10个河道取水口后，我们的‘水缸’直接搬到了河边。 “Since the energy crisis started, Mexico has used 72 percent of its crude oil exports to the United States,” Obrador said. “While we’re waiting for prices or gasoline to go down in the United States, we have decided that it was necessary for us to allow Americans who live close to the border… to go and get their gasoline on the Mexican side at lower prices.”,Obrador made the remarks before his bilateral meeting with US President Joe Biden at the White House.,Global Economy Will Plunge Into Long Recession in Coming Years, Prominent Investor Warns07:03 GMT,Over the past months, the United States has been experiencing accelerating inflation, which the Biden administration has dubbed "Putin's price hike" and blamed on many additional factors.,However, the majority of Americans see inflation as a result of the Biden administration policies and consider it the top problem, given the increasing energy, food and other prices cutting deep into consumer's spending power.。”开了8年洒水车的冯水良说，现在出车前顺路就能完成补水，方便又省心。截至目前，全市已累计布设河道取水口104个、再生水取水栓23个，一张覆盖城区的环卫“第二水源”补给网正越织越密。有人疑惑：用河水、再生水洗路，会不会影响保洁质量？答案藏在精细化“分质供水”方案里：洒水车出水口径大、自带粗滤装置，日均耗水量高，优先取用净化河道水和再生水；高压洗扫车喷头精密，选用悬浮物更低的再生水，减少设备堵塞磨损；雾炮车对水质要求更高，仍采用自来水。与此同时，养护人员会定期清洗更换取水滤网、疏通管路、检修高压喷头和水泵核心部件，让每一辆环卫车都“喝得顺、跑得稳”。节水更要算好经济账。经多轮实测，当取水半径控制在3公里以内时，综合用水成本明显低于自来水，也不会挤占正常保洁作业时间。如今，各保洁单位都会提前摸排就近河道取水点和再生水桩位置，提前规划作业路线，尽量不让车辆空驶找水。“少跑冤枉路，多干实在活，成本降了，效率反而高了。”一名保洁负责人坦言。从“全靠自来水”到“第二水源挑大梁”，当越来越多环卫车用上“循环水”，杭城的水资源节约之路，也越走越宽。
