- 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 City With 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).

- 11. FLOW DIAGRAM OF MPDT CONCEPT IMPLEMENTATION “Flow Diagram of MPDT Concept ”
- 12. I. Pre-Feasibility Study (FS) to Basic Design This 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 Design 3) 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 Design 1) 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.
- 15. III. MPDT Implementation Once FS and Detailed Design are completely done, next phase is to implement MPDT by the investor consortium through EPC system (Engineering, Procurement, & Construction) which consist of work items as follow: A. Deep Tunnel 22 km including Holding Pond, Flood Forecasting and Warning Center, Weather Radar and Rain gauge Station, Sea Outfall Turbine Pump plus Surge Chamber; B. Toll Road 18 km including Ingress and Egress, Motorway Control Center, Safety Features including Escape Routes and Fire Hydrants ; C. Sewerage system consist of Main Trunk, Secondary, Tertiary Pipe Networks and Water Reclamation Plant; D. Utility Shaft.
- 16. IV. Operational Management 1) This phase is not only expected by public at large but also by government and investor. 2) Considering that MPDT is a multi purpose, integrated and accurate monitoring and controlling are crucially important (for instance : integration among the SOP of flood control, toll road operational management and its safety features, sewerage system, etc) 3) Controlling of each component, consist of : a. Revenue Collection b. OM Costs c. Tariff adjustment d. etc.
