Why Songdo
Sustainable City
Water
- The Central Park canal uses seawater instead of fresh water, saving thousands of liters of potable water per day.
- Irrigation-based potable water use will target a 90% reduction versus international baseline, reduced through the use of efficient landscape design, water-saving irrigation systems, reclaimed stormwater and reuse of treated greywater from a city-wide central system.
- Potable water comsumption in plumbing fixtures will target a 20-40% reduction based on the use type of the project.
- Stormwater runoff will be used to the maximum extent possible given the project's climate zone and annual rainfall pattern.
- Vegetated green roofs will reduce stormwater runoff, mitigate the urban heat island effect and promote biodiversity and species habitat preservation.
