Multi Purpose Deep Tunnel (MPDT) An Integrated Solution for Flood Control, Water Supply, Waste Water, Water, Road Tunnel and Public Utilities in the Jakarta Mega City Presented to : Singapore International Water Week (SIWW) 2008 June 25, 2008 Suntec Singapore International Convention & Exhibition Centre - Water Leaders Summit and South East Asia Business Forum FIRDAUS ALI, PhD. Jakarta Water Supply Regulatory Body AN AI AN R Y MI A L NE UP M (JWSRB) 1
  • 2. Environmental Serious Problems being faced by Mega City of Jakarta.1) Floods, paralyzing the city (Business, Industrial and Municipal damages); a) 2002 Flood damages IDR 9.9 Trillions b) 2007 ditto IDR 8.8 Trillions TOTAL IDR 18.7 Trillions (eq. to USD 2.05 Billions)2) Raw water scarcity and also badly polluted;3) Water supply coverage ratio, only around 55 %;4) Untreated waste water, causing water borne diseases due to e-colli;5) Excessive abstraction of Ground Water, causing land subsidence and sea water intrusion as well as worsening the flood control management;6) Traffic congestion is severe, causing national loss IDR 43.3 T/annum (eq. to USD 4.76 B/annum);7) Climate change worsen the situation.

  • 4. MULTI PURPOSE DEEP TUNNEL (MPDT) An Integrated Solution for Flood Control, Water Supply, Waste Water, Road Tunnel and Public Utilities in the Jakarta Mega CityWith the Following Benefits;1. Controlling peak flood;2. Improving urban wastewater management, including Water Reclamation Plants (WRPs) to : Supply clean water for the Northern part of Jakarta; Improve water quality in water bodies; Produce electric power (methane gas) and organic fertilizer.3. Reducing ground water abstraction due to improved city piped water service due to a more reliable supply of raw water;4. Constructing of tunnel need no land acquisition except for holding pond and ingresses + egresses of toll road;5. Utilizing the tunnel as toll roadway as in SMART project (KL) and utility shaft, as in TARP project (Chicago).

  • 12. I. Pre-Feasibility Study (FS) to Basic DesignThis phase comprises of :1) Technical Aspect, for Geological aspect and Hydro Geology, Soil Investigation, Flood Control, Traffic System Engineering and Management, Waste Water Management and its Reclamation Plant, Utility Shaft, Civil/Structural Engineering Mechanical and Electrical Engineering, Health and Safety Engineering.2) Economical Aspect, economical aspect is needed to observe to what extent investment is economically feasible to mitigate the impact of flood damages and address economical benefit.
  • 13. Continued..I. Pre-Feasibility Study (FS) to Basic Design3) Ecological and social culture aspect, which comprises of : A. Environmental/ecological impact in development phase and operation and maintenance phase. B. Cultural social aspect, especially for those community reside along side Ciliwung river and west flood way including acceptability level.4) Financial aspect, is needed in identifying to what extent private sector including BUMN and BUMD both national and foreign investment are financially feasible (FIRR, schematic fund and concession period)
  • 14. II. Feasibility Study (FS) to Detailed Design1) After Pre-Fs is accepted by the government, the stages of FS and detailed design shall be continued by the proponent;2) The result of FS and detailed design shall become a basis for negotiation process based on BOT scheme, or tendering process under PPP scheme between Government and Private sector;3) The negotiation or tender result as mentioned above, shall become a baseline for entering the contract agreement between government and related private sector, based on pre determined of concession period.
