Non-Potable Water
非饮用水
Non?potable water refers to water that does not meet drinking water standards, such as wastewater and collected rainwater.
非饮用水指不符合饮用水标准的水，例如废水和收集的雨水。
Buildings use potable water and generate wastewater, which is water that has been used for a purpose and conveyed by building plumbing systems toward a point of treatment and disposal.
建筑使用饮用水并产生废水；废水是经过使用后，由建筑管道系统输送至处理和排放设施的水。
In addition to the treatment plants that provide potable water, municipalities also have plants to treat the wastewater from buildings before it is released into rivers and lakes.
除供应饮用水的水厂外，市政部门还设有污水处理厂，对建筑排出的废水进行处理后再排入河湖。
Even once it has been treated, this water still contains some contaminants that can disrupt aquatic ecosystems.
即便经过处理，这类水体仍含有部分污染物，可能破坏水生生态系统。
In some cases, large amounts of wastewater can overwhelm treatment facilities, causing untreated overflow that contaminates rivers and lakes with pollutants.
部分情况下，大量废水会超出处理设施负荷，导致未经处理的污水溢流，污染河湖。
Buildings generate different types of wastewater that have different potential treatment options.
建筑会产生不同类型的废水，对应不同的处理方式。
Graywater is wastewater from sinks, tubs, showers, and clothes washers that has not come in contact with toilet waste.
灰水：来自洗手池、浴缸、淋浴、洗衣机，且未接触马桶污物的废水。
Green Building Strategies
绿色建筑策略
Green buildings leverage non?potable water to further reduce demand for potable water.
绿色建筑利用非饮用水，进一步降低对饮用水的需求。
Strategies include:
策略包括：
Installing on?site systems that enable treatment and reuse of non?potable water, such as wastewater and captured rainwater. Options for these treatment systems include off?the?shelf technologies and on?site constructed wetlands that clean wastewater while also providing a habitat.
- 安装场地内系统，实现废水、收集雨水等非饮用水的处理与回用；可采用成熟成套技术或人工湿地，在净化废水的同时提供生物栖息地。
Investigating whether the district or municipal utility that serves the building offers access to alternative sources of water.
- 调研服务本建筑的区域或市政水务部门是否可提供替代水源。
Even if water treated on site does not meet potable water standards, it still can be reused for other purposes on site, including flushing, irrigation, and cooling towers.
即便场地处理后的水未达到饮用水标准，仍可在场地内回用，例如冲厕、灌溉、冷却塔用水。
