125m DN1200 Drainage Pipeline Rehabilitation in Taiwan
Dec.02,2025
Project Overview
EasySight proudly delivered a critical infrastructure renewal project in Kaohsiung, Taiwan, rehabilitating 125 meters of DN1200 drainage pipeline using advanced trenchless CIPP technology. This zero-disruption project reinforces urban flood resilience while minimizing environmental and community impact.
Operational Challenges
The rehabilitated pipeline is a key component of Kaohsiung's stormwater management system. Aging infrastructure risked reduced flow capacity and potential collapses, threatening urban resilience during typhoon seasons. Traditional excavation would have caused significant traffic disruption and environmental damage.
Advanced Trenchless Solution
CIPP Technology: Deployed resin-saturated liners cured-in-place to create seamless, jointless pipe-within-a-pipe structural renewal.
Large-Diameter Expertise: Leveraged specialized equipment for DN1200 scale – within our certified DN150-2200 diameter range.
Zero-Disruption Execution: All works conducted subsurface, preserving roads, landscapes, and daily community activities.
Project Outcomes
✔ Restored Flow Capacity: Eliminated infiltration/inflow defects, achieving optimal hydraulic performance.
✔ Durable Renewal: High-strength CIPP liner withstands abrasion, corrosion, and ground loads.
✔ Community Benefits: Zero surface disruption maintained traffic flow and public safety.
