TOTAL IDR 18.7 Trillions

(eq. to USD 2.05 Billions)

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

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.

MULTI PURPOSE DEEP TUNNEL (MPDT)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).

I.I. PrePre--Feasibility Study (FS) to Feasibility Study (FS) to Basic DesignBasic Design

This phase comprises of :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.

3) Ecological and social culture aspect, which comprises of :

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)

B. Cultural social aspect, especially for those community reside

along side Ciliwung river and west flood way including

acceptability level.

I.I. PrePre--Feasibility Study (FS) to Feasibility Study (FS) to Basic DesignBasic Design

Continued..Continued..

A. Environmental/ecological impact in development phase and

operation and maintenance phase.

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.

II. Feasibility Study (FS) to Detailed Design II. Feasibility Study (FS) to Detailed Design

III. MPDT Implementation 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.

IV. Operational ManagementIV. 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.
