提纲初稿：
Questions about the difference between the actual readings of water usage before and after the adjustment, the change of showerhead’s service life caused by the adjustment and the percentage of residents complain about the adjustment should be answered.
To begin with, the question about the difference between the actual readings of water usage before and after the adjustment needs to be answered because the water may have been used more after the adjustment.虽然单位时间花洒喷水量降到三分之一，但可能导致人们花更多的用水时间，导致总体用水量增加。
In addition, the question about how service life of the showerhead has changed since the adjustment is need to be answered.水流量减小会导致花洒内水垢沉积速度加快，花洒使用寿命减短，更换花洒频率增高，成本增加。人工成本
Finally, what the percentage of residents complain about the adjustment should be answered.人们没有大面积反映问题不代表没有意见，应该进行民意调查，以免给人们的生活带来不方便。

讨论笔记：
人们会延长shower的时间，盆浴，能否节水
成本是否降低：换花洒头的人工成本,
投诉渠道是否畅通，导致居民不满意则不住在这里了，会不会流失tenant，收入降低，利润减少。
如果真的成本减少那么能否大量减少。水的成本占总的比例是多少，比例较小的话则不可能大量减少
