An aqueduct supplies clean, fresh water to a settlement. Simply by separating water supply from any contamination by raw sewerage, contributes enormously to the general health of the population. That people can also wash is simply a bonus! Even in severe droughts, the settlement will usually have water.
城市水渠與腐臭污水相互隔離,為城邑提供潔淨新鮮水源,故而極大改善居民健康狀態,有時居民們甚至在水中沐浴嬉戲。即便乾旱之年,水渠仍能保證城邑的日常用水。 |
