Lately, Indonesia one of the biggest population country has a problem with flood disaster, specially Jakarta as the capital city. To solve this problem, Indonesia make a concept of water purification system which is called The Ciliwung Recovery Program (CRP). This Water purification concept (CRP Project) is basically to continue the Waterway concept which is involving over 13 rivers in Jakarta specially the Ciliwung river, and with the CRP Project, the Waterway will can be realism. Because of the crowd population, Ciliwung often facing river polution. The CRP project is mainly a building which will help Ciliwung river cleaning herself and there is step and tools which is already prepare to purify the polluted water. If this project can work in maximum way, Indonesia-specially Jakarta will never worry about long rainy season and probably the Ciliwung Recovery Program (CRP) will also can be used as renewable energy through wind, solar, and hydroelectric systems.

The Ciliwung Recovery Program (CRP) is a project that aims to collect garbage from the banks of the river and purify the water through a clever system of mega-filters that operate in three different stages. The first is to separate different types of waste and using organic one to cultivate the land. The second stage of purifying water by removing harmful chemicals and minerals essential to add it. Clean water and then fed to the river and into the fields of agriculture through a capillary tube system. Finally in the third phase, all waste will be processed through the recycling mechanism.
