NIKKEN SEKKEI URBANISMTECHNOLOGY & URBAN DEVELOPMENT098 _ 099MANAGING WATER FOR BETTER LIFEDamuwan stands against Damuwanyang Bay, which directly joins the East China Sea to the east, 60 km from Ningbo City in China’s Zhejiang Province. The vitality of the future bay-side resort depends on a coherent long-term strategy for sustainable water management.Despite being a coastal city surrounded by water, Damuwan has been suffering from water-related crises for a long time. Shortage of potable water and frequent floods caused by torrential rainfalls, as well as poor water quality due to its saline-alkali soil property and up-stream water pollution provide severe challenges for the future development of the area.Four general water-management strategies for the 14 sqm site have been introduced with the objective of improving the quality of daily water supply as well managing the local natural water system in a sustainable way. Adjustments to river courses are expected to improve their storm water drainage and storage performance. Shoreline sections are intended to be modified to provide people with a more enjoyable waterfront. Introducing technical and ecological purification systems will improve potable water quality and encourage non-potable water use in daily life. A storm water management plan, which includes the development of a new storm water control analysis model for the city, will reduce surface runoff overow and to balance water storage to a more stable level.Damuwan Eco City Integrated Water Management System | Damuwan, China, 2010 Site Area: 1,400 hectaresFARMLANDEMBANKMENTPURIFICATION WETLAND7.0 Embankment High3.46 Flood Level1.50 Normal Water Level-0.50 Bottom LevelLand use master plan of Damuwan Eco CityNSC
