Use AI-powered and modular inspection product to improve Singapore’s Urban Drainage Systems

Keywords: AI-powered, modular design, complex inspection, high-water

Located in the tropics, Singapore experiences abundant rainfall and complex terrain, making the maintenance and inspection of its urban drainage system crucial. Our AI-powered inspection solutions have assisted the PUB, Singapore's National Water Agency in completing comprehensive pipeline assessments.

This project encompassed full-scale inspections of stormwater drains, GIS data collection, and the application of artificial intelligence algorithms to enhance the efficiency and management of Singapore’s urban drainage infrastructure.
