Removal of surface water from the road or street is known as surface drainage.

从道路或街道排除表面水被称为地表排水。

The whole city drainage system program is as follows: rain water wells road, clay and drain well across the street and drainage inspection wells and underground drainage main lines.

市政整体排水系统程序如下：路面雨水→雨水井→沉泥井→过街排水管→排水检查井→地下排水主干线。

Entering into the village, one can see the stone steps and ancient streets stretching more than 2,600 meters; with good links, good drainage, the street remain the dry even a rainy day.

走进黄家塝村，青石台阶映入眼帘，石板古巷绵延2600余米，纵横相连、排水良好，即便是雨天也能保证路面的干爽。
