优选的，所述供水组件由供水管11构成，供水管11起接于水箱3下部、通连至使用二次用水的设备12，当需要二次用水时，二次用水通过重力作用从水箱3经供水管11进入使用二次用水的设备12供使用；
优选的，所述运水组件由溢水管7构成，溢水管7起接于本楼层水箱3上部、连通下一楼层水箱3顶部，当本楼层二次用水富余时，则通过溢水管7将富余的二次用水从本楼层水箱转运至下一楼层水箱储存备用，若以下楼层仍有富余时，则依此逐级往下一层转运；
优选的，所述排水组件包括排水管9、排污管10、次排水管13，排水管9连接输水管4和排污管10，次排水管13连接使用二次用水的设备12和排污管10，当本楼层设备2使用自来水后产生不宜再次使用的二次用水时，则关闭第一开关14，使无法使用的二次用水直接从排水管9排至排污管10排出；排水管9的中部高于其与输水管4的接口，以在输送可使用的二次用水避免从此溢出；次排水管13连接用水设备12和排污管10，排出用水设备使用二次用水后产生的污水；
优选的，所述自来水进水组件包括自来水进水管5和浮动闭水阀20，自来水进水管5连通自来水水管，浮动闭水阀20设于自来水进水管5下端且与其匹配连接，当水箱3中得不到充足的二次用水补给，水位逐渐下降，浮动闭水阀20在重力作用下也随着水位下降，当到达一定位置时，开启自来水进水管5向水箱3中注入自来水，以弥补二次用水水量的不足；当水箱3中水位上升，浮动闭水阀20随着水位上升的浮力支撑作用也向上，到达一定位置时关闭自来水进水管5，停止向水箱3中注入自来水。
进一步的，一种节水系统，在大楼除最高层以外的其它楼层，均重复配置所述水箱以及设于所述水箱3上的二次用水输水组件、供水组件、运水组件、排水组件和自来水进水组件，以确保上一楼层产生的二次用水能够输入下一楼层水箱储存备用，直至从上往下逐楼层将各个水箱均装满的情况下，才从最底楼层水箱的溢水管排出，提高二次用水的使用效率。
以上所述仅是本发明的优选实施方式，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
