• The elevation difference between

Jakarta -Bogor, and Jakarta - Bandung

are 258 and 761 m.

• Water from Bandung and Bogor are

flowing to Jakarta through Citarum,

Cisadane, and Cisadea rivers with

average debit of approximately 60, 55,

and 10 m3/s.

BACKGROUND

• Currently, Jakarta suffers from annual flood disaster. In

2002, losses due to flood in Jakarta was approximately US$

980 millions and can increase to US$ 2 billions in 2013.

• Jakarta currently deficit 10m3/s of clean water and will

increase to 19m3/s by 2020.

• Water feeding from Bandung and Bogor is one of the major

contributor of flooding and is aggravated by the littering

habits of the society and industries along Ciliwung,

Cisadane, and Citarum rivers.

ECONOMIC ANALYSIS AND BENEFITS

• Horizontal axis single and double runner

Francis turbine is utilized to generate 2.64 and

13.84 MW (required water rate: 10 and 50 m3/s )

• Water exiting from the turbine is supplied to

water (Micro filtration) treatment system with

capacity of 114MGD.
