- Business with the purpose of reducing the risks of private and public property damage by expanding waterproof areas subsequent to urbanization, resolve internal water treatment issues subsequent to internal water level increase and plan drainage pump stations subsequent to increased flood damage scales, and preventing surface water and underground water quality degeneration subsequent to flooding of public facilities nearing rivers.
- Business to prevent disasters through drainage pipe expansion and construction in frequent flooding areas while promoting local economic development
- Business for early emergency recovery regarding water damage areas subsequent to localized downpour
Leakage assessment
- Water leakage assessment and waterworks inspection in supply areas to reduce water leakage and improve water flow rate, while promoting streamlined operation of water supply pipes and preventing safety accidents
