Second place winner of the eVolo 2010 Skyscraper Competition
I came across this beaut in Inhabitat which had this to say:
Dubbed the Ciliwung Recovery Project (CRP), the design took second place in the competition thanks to its amazing concept, beautiful design and ecological benefits. The project provides housing and features an integrated filtration system consisting of a series of tubes that pump and purify waters from the region’s polluted rivers.
More on the entry from eVolo’s website
Ciliwung Recovery Program (CRP), a project aims to purify the Ciliwung River’s environment to its original form. Through the new system in the building, CRP is expected to be able to repair and become the sustainability generator for Jakarta.
There are three main lines in the process of purifying the Ciliwung river, first line is the flow of the polluted river water into the building through pipes by utilizing capillary vessel systems, into the filtrating section. …
The second line is the phase of river water purification through elimination of dangerous contaminants, and addition of various good minerals to the water, so it is safe for daily needs of CRP building occupants. …
The third line is the re-processing of household waste products into water which is safe to be returned to the Ciliwung River. …
