Modernizing Taiwan's Urban Drainage: Advanced Solutions for Extreme Rainfall
Dec.02,2025

Project Background
Taiwan experiences annual rainfall exceeding 2,500mm - among East Asia's highest precipitation levels. While achieving rapid economic growth as one of the "Four Asian Tigers" since the 1960s, its drainage infrastructure development lagged behind industrial expansion. This disparity intensified urban flooding risks in major population centers.Kaohsiung Water Resources Bureau implemented the NT$80 Billion (8-Year) Flood Control Plan. This plan completed 13 critical drainage system upgrades and initiated ongoing pipeline network rehabilitation and expansion.
Technical Challenges
1. High-Water/High-Sediment Conditions: Conventional inspection equipment impaired by silt and debris
2. Urban Space Constraints: Traditional excavation methods worsen traffic congestion
3. Seasonal Time Pressure: Narrow maintenance windows between monsoon seasons
