By upholding the core value ‘Professional, Innovative, Sustainable’, over the past fifty years or so, we have made remarkable contributions to Taiwan’s water resources planning. These included planning visionary water resource policies; leading the R&D of leading-edged water resource technologies; planning and testing major water resource projects; building a knowledge base to share all knowledge about water resources; and improving the core R&D competencies of employees. In the future, we will continue to lead Taiwan’s water resource planning to a new age.
