Difference between drains and sewers。
A drain is a pipe that serves only one building, conveying water and waste water away to a sewer. A lateral drain is a section of drain positioned outside the boundary of a building, connecting with the drains from other buildings to become a sewer.。
Sewers (sewerage), are the underground networks of pipes that carry sewage (waste water and excrement), waste water and surface water run-off, from drains to treatment facilities or disposal points.。
排水管是仅用于一栋建筑物的管道,将水和废水输送到下水道。 侧面排水管是位于建筑物边界外部的排水管,是排水管的一部分。一栋建筑物的排水管与其他建筑物的排水沟相连成为下水道。
下水道是地下管道网络,用于承载污水(废水和排泄物)、废水和地表水。把这些水从排水管(drain)引流到污水处理厂等地方。
