The Futian River has been channelized into a rainwater runoff and waste streams. The rainwater flows above ground, creating a walking area, which winds through the Municipality’s central park. The waste stream flows through underground tubes, unseen and unnoticed, unless one manages to the wastewater treatment center further downstream. The effect of separating the streams has been to create a cleaner environment, literally burying the problem.
Now, whether or not a Shenzhen river can be separated into rainwater runoff and wastewater tubes depends on the level of industrialization upstream. Thus, for example, the City efficiently handled the relatively underdeveloped Yantian River (in the East), while remains undecided about what to do with the Buji River. Consequently, lest we forget that water quality remains an issue throughout the city, upon crossing the silvery clean Futian River into Tianmian, one encounters literally hundreds of plastic bottles of drinking water.
