Project name            Pilot of catchment area network for city’s green infrastructure

Site location              Phraya Suren canal and Bang Chan canal, Bangkok, Thailand

Project area              562 rai (Canal area: 100 rai, Retention ponds area: 293, 130, 39 rai)

             The project is one of the six increasing retention pond projects in eastern Bangkok managing by Department of Drainage and Sewerage. It is in suburb of Bangkok where nowadays are risk of urban expansion like housing estate and commercial area. The concept of water management is integrated typical Bangkok retention pond design with rice field which is the original site context. It is a form of polder that can collect the water already. Unlike the typical Bangkok retention pond that does not take concern in ecological factors and some process is illegal.

 

            The purpose of the project is to adapt water management with the suburbs area. Which using rice field context can reduce the problem of urban sprawl and deal with the global warming that causes the unusual weather such as localized clusters rainfall, for example using rice fields or that connect each other with the main canal to distribute water volume in canal to low rainfall intensity areas.

 

            The traditional rice cultivation learning centre and using rice field with water management would reduce the expansion of the city to the suburbs or agricultural areas and collect water before flowing through the inner city. It can also be used as a pilot model for retention pond water management cooperated with rice fields around the suburbs without buying land, but make agreements with farmers to help increasing flexibility and quickly to provide water catchment area when the sudden climate change.
