美国加州发布最严节水令 CEC发布新规

         

      美国加州地区正面临用水短缺，加州州长杰瑞﹒布朗紧急呼吁加州各城镇将用水量削减25%，并出台一系列强制性的节水规定。此后，美国加利福尼亚能源委员会(CEC: California Energy Commission)一致通过了相关用水装置新规定，文件编号15-AAER-4，新规自2016年1月1日起生效。

      此次CEC新规规定：自2016年1月1日起，所有在售的住宅卫生间的水龙头应不超过每分钟1.2加仑的流量；厨房水龙头应不超过每分钟1.8加仑的流量，但允许其具备暂时增加到每分钟2.2加仑的功能；公共厕所水龙头应不超过每分钟0.5加仑的流量；马桶和小便池，除了那些用于监狱或精神卫生保健设施的（这些设施有专门的设计用来解决安全和健康问题）马桶冲水不消耗超过1.28加仑，并且需要有不少于350克的冲厕分数；挂墙式小便器冲水不消耗超过0.125加仑。自2016年1月1日起，相关卫浴产品如若达不到此要求，将可能面临拒绝在加州销售的风险。
