Design Standards of Urban Roads and Accessory Works Article 24
Regulations governing the drainage designs of urban roads:1. Where rainwater drainage systems have been planned prior to the construction of new urban roads or road expansions, please refer to existing plans and design of system. Where no rainwater drainage systems have been planned, appropriate drainage facilities shall be designed, the capacity of which shall be able to accommodate the amount of rainwater catchment area on the road surface.2. A gravitational drainage system shall be employed. However, pumps may be installed in road sections where elevation makes such system non-viable.
中文原文 市區道路及附屬工程設計標準第24條
市區道路排水設計規定如下：
一、市區道路新築或拓寬時，已有雨水下水道系統規劃地區，參照其規劃為之。
無雨水下水道系統規劃地區，依據道路集水面積範圍內所需容納之排水量，設計適當排水設施。
二、採重力式排水。
但受地形高程限制者，得依需要設置抽水設備。
