Riverside townships, especially slums, polluting the watershed enclosures are posing a serious threat to almost all the major rivers across the world. Providing a solution, the Ciliwung Recovery Program (CRP) by a bunch of designers, including Rezza Rahdian, Edwin Setiawan, Aayu Diah Shanti and Leonardus Chrisnantyo, has come up with a sustainable skyscraper to purify the contaminated water of rivers by utilizing renewable energy. Intended toward the Ciliwung River in Jakarta, the revival program is planned to be accomplished under three main stages.
First, the contaminated water of the river is moved across the building, through a network of pipes by using capillary vessel systems, to remove the garbage from the water. In the second phase, various minerals are added to eliminate the unhygienic contaminants from the water to make it safe for drinking and other daily needs. In the third and final stage, the household waste is recycled into clean water, so it could be poured again into the river. In addition, the façade of the building features a number of wind generators to harness wind power, while a massive solar reactor located at the top captures solar energy to fulfill its energy requirements.
