| Human development drives demand for potable water — that is, clean water that is suitable for drinking. |
人类发展推动了对饮用水的需求——即适合饮用的清洁水。 |
| Historically, most projects rely on municipal sources of potable water to meet all their needs, from flushing toilets to washing dishes to irrigating landscapes. This high demand for potable water strains supplies and, under extreme conditions, necessitates water rationing. However, potable water is only needed in instances where water is in contact with humans, such as water used for drinking, showering, cooking, and handwashing. |
从历史上看，大多数项目依赖市政饮用水源来满足所有需求。这种对饮用水的高需求使供应紧张，在极端条件下需要实行配水。然而，饮用水仅在与人接触的情况下才需要，例如用于饮用、淋浴、烹饪和洗手。 |
| To provide potable water, treatment plants pull in freshwater and use chemical processes to purify it by killing microorganisms and removing most hazards, so that it is safe to drink. This treatment comes at a huge public cost. |
为提供饮用水，处理厂从河流等水源抽取淡水，通过化学过程杀灭微生物并去除大部分有害物质。这种处理需要巨大的公共成本。 |
