Environmental Serious Problems being faced byEnvironmental Serious Problems being faced byMega City of Jakarta.Mega City of Jakarta.
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.
