Aerial rendering of "[Re]Flow Can Tho" by Shivani Agarwal, Hsin Yi Chao, Greg LeMaire, and Tanaya Kadam.

[Re]Flow Can Tho

Can Tho was built on top of an ever-changing, watery, delta landscape. This delta is sinking as urbanization consumes more groundwater and the sources of groundwater recharge such as wetlands are diminished. This culture that has traditionally lived with water, is being disconnected from it by rapid urbanization and a focus on land and road based development. By introducing a new system of urban water flow over the existing city fabric, [Re]Flow reimagines how Can Tho lives with water. A network of canal-like spillways will be cut through existing overbuilt roads, reviving a lost system of tandem road and canal based development. To allow for safer interaction with the urban waterways, reflow will also completely remove sewage discharge from the canals through a distributed system of constructed wetlands, built on existing green spaces, which will treat the wastewater and use the treated water to recharge groundwater. [Re]Flow increases the city’s ability to live with water and respond to its changing dynamics.
