1.2 Project Location

  1.3 Background of the Project

Jakarta is the preeminent urban center of Indonesia. It is the main commercial hub of Indonesia. Regional urbanization

has contributed to making Jakarta one of the largest metropolitan areas in the world. The Special Capital District of Jakarta

  2

(DKI Jakarta)1 covers an area of approximately 650 km with a population of about 9.6 million in 2010, while the population

  2

  2

  2

of Greater Jakarta (covering about 7,300 km ) stood at 27.9 million . Rapid growth and inadequate development of public

services have contributed to a host of problems the most severe of which are manifested in disastrous perennial flooding.

  

Flood management infrastructures in Jakarta. Greater Jakarta is surrounded by several dormant volcanoes whose

slopes form the upstream catchment areas of the 13 major rivers that flow through Jakarta to the Java Sea. The rainy

season begins in late November and ends in early April. Jakarta sits in the lowest lying areas of the basin. Forty percent of

Jakarta lies below sea level, including most of North Jakarta, which is being severely threatened by acute land subsidence.

The basic principle of flood management in Jakarta is to divert peak flows from upstream areas around the core of the city,

directing flows to the East and West of Jakarta via two major flood canals emptying into Jakarta Bay. Within the city, the

macro drainage system consists of 13 rivers and a large number of drainage channels. The macro drainage system can be

divided into several subsystems that are separated by floodgates. In low-lying areas, there are polders, which are protective

systems that utilize retention reservoirs at the lowest point and regulate excess water levels by pumping out of the system.

Poor condition of the system, under-implementation of operations and maintenance (O&M), and inadequate local drainage

management result in rapidly occurring inundations during rainfall conditions.

  

Causes of flood in Jakarta. The overall urbanization trends are central to the causes of Jakarta flooding. This has led to

the deterioration of several critical factors. The encroachment and/or development of critical catchment areas have resulted

in both increased rainwater runoff and lack of natural stormwater retention areas both within the city and in upstream areas

of the catchment. Increased generation and inadequate management of solid waste have contributed to waste choked

canals and floodways, exacerbated by insufficient maintenance resulting in weakening structures and sediment build-up.

  

Some canals are operating at less than a third of their original capacity. Land subsidence continues at increasingly alarming

rates, principally caused by intensive deep groundwater abstraction. Land subsidence results in increased vulnerability to

flooding due to the reduced gravitational capacity to channel storm flows to the sea and an increased risk of tidal flooding.

  

Flood management institutions in Jakarta. Responsibility for the development and management of flood infrastructure in

Jakarta is shared between two central government agencies and the Provincial Government of DKI Jakarta (DKI) i.e. The

Balai Besar Wilayah Sungai Ciliwung - Cisadane (BBWSCC)3 under the Directorate General of Water Resource (DGWR) of

the Ministry of Public Works and Housing (MoPWH); the Directorate General of Human Settlements (DGCK) of the MoPWH;

and DKI, through its provincial public works office (DTA-DKI)4, is responsible for the remaining drains, floodways and

retention basins.

  1.4 Project Objectives

The Project Development Objective (PDO) of the Jakarta Urgent Flood Mitigation Project/Jakarta Emergency Dredging

Initiative (JUFMP/JEDI) is to contribu te to the improvement of the operation and maintenance of priority sections of Jakarta’s flood management system. The PDO will be achieved through: a) Dredging sections of selected key floodways, canals and retention basins to improve their flow capacities, and disposing the dredge material in proper facilities; b) Rehabilitating and constructing embankment in sections of, and repairing or replacing mechanical equipment in,

the same selected key floodways, canals and retention basins to sustain and improve their operations;

c) Establishing institutional coordination between the three responsible agencies to encourage coordinated development, and operations and maintenance (O&M) of Jakarta's flood management system, and

d) Strengthening the capability of the responsible agencies to improve the operations, maintenance and management of Jakarta's flood management system.

  1 Jakarta is officially designated a province with special status as the capital of Indonesia i.e., DKI Jakarta (or ‘Special Capital City District of Jakarta’).

  2 More than double the population of 11.9 million in 1980.

  3 River basin management agency for the Ciliwung and Cisadane rivers, which is a Central Government institution designed to function as a river basin organization.

  

4 And further supported by its sub-dinases (or sub-departments at the municipal level). Administratively, DKI Jakarta is divided into five municipalities (i.e , North Jakarta, South

.

  Jakarta, West Jakarta, East Jakarta and Central Jakarta municipalities) and one regency (i.e., Kepulauan Seribu, a group of small islands located on the Java Sea).

1.5 Construction Packages

  

The ultimate goal is to improve Jakarta’s flood management system and reduce the time and duration of floods by dredging

selected floodways, channels and retention basins and to dispose of the excavated (or dredged) materials at three managed

facilities each being many kilometers from the proposed construction sites. As discussed in other sections of this Inception

Report, there are 13 (thirteen) rivers flowing northwards through Jakarta. These form its macro drainage system. Overtime,

poor operation and maintenance (O&M) and ineffective solid waste management, has resulted in significant sediment

deposition and solid waste build up. Additionally, uncontrolled (intentional) upstream land development has resulted in both

increased surface runoff and lack of natural storm water retention areas due to the alteration of the surface (less forested

areas, more houses and roads, etc.). Effects of climate change has also changed the hydrology of the region resulting in

intense and longer duration downpours at times and shifting of the timing of wet and dry seasons.

This Project will focus on 11 (eleven) channels and 4 (four) retention basins which have been identified as priorities. The

major scope of works under the Project include the following: (i) dredging of floodways, channels, and retention basins and

disposing the excavated material at three separate disposal facilities; (ii) rehabilitating and constructing embankments and

repairing or replacing mechanical equipment on various structures, and (iii) constructing Sentiong pump station

One management concern with respect to this Project will be the development of effective coordination and cooperation of

three separate government authorities. Under Indonesian law, the Ministry of Public Works and Housing Affair (MoPWH),

[through two departments - DGHS and DGWR], and the provincial government of Jakarta, DKI are responsible for managing

different aspects of Jakarta's flood control system. The MoPWH departments are responsible for floodways that cross

provincial boundaries; while the Jakarta Public Works Department (DTA-DKI) is responsible for drains and retention basins

within its boundaries. For this Project, these are the works that are under the three separate authorities: Under MoPWH-DGHS: (i) Tanjungan drain, (ii) Lower Angke drain, and (iii) Cideng-Thamrin drain;

Under MoPWH-DGWR: (i) Cengkareng floodway, (ii) West Banjir canal/floodway, (iii) Lower Sunter floodway; (iv) Upper

Sunter floodway, and (v) Sentiong Pump Station;

Under DPU-DKI: (i) Ciliwung-Gunung Sahari floodway, (ii) Sentiong-Sunter drain (including Ancol canal), (iii) Grogol-

Sekretaris drain, (iv) Pakin-Kali Besar-Jelakeng drain, (v) Krukut-Cideng drain; and (vi) Krukut Lama drain; and

Under DPU-DKI: (i) North Sunter retention basin, (ii) South Sunter retention basin, (iii) East Sunter III retention basin, and

  (iv) Melati retention basin.

  3 are estimated to be solid

waste). About 42.2 km of embankments are expected to be rehabilitated or constructed within these floodways, canals and

retention basins. Details of the project achievement to this period summarized in Table 1.5 below.

  6 Solid wastes larger than 30 cm x 30 cm will be separated from the dredge material and disposed of separately.

  

under the bridges and other obstacles including sediment on the embankment will be removed as well. All dredging works

will be executed from the water, except some temporary disposal and the truck loading works.

All equipment used for the removal (excavation) of the sediment must be able to position themselves in the water during

dredging operations with spuds. This is to guarantee that each section of the drains, floodways and waduks are dredged.

Damage of embankments, obstacles or any other assets before, during and after the dredging works will be repaired.

  1.5.4 Transportation Methods

  7 All transport of sediment should avoid leakage or spills and dump trucks should be 100% watertight . Any leakage of the

dump trucks on the truck loading location and along the route to the disposal sites will be cleaned immediately. Each truck

movement, limited to 22.00 pm to 05.00 AM, will be registered. In particular, for disposal at Ancol CDF, this will include daily

reports mentioning type of truck, license plate number, time of truck departure from the loading location, and time of arrival at

the deposit area in Ancol CDF.

  1.5.5 Sequenced Project Implementation

A sequenced implementation design has been adopted as a key implementation risk management mechanism for the

project. Table 1.6 summarized the Phase 1 and Phase 2 sites.

approximately 3.4 million m of sediment material and the approximately 95,000 m of solid waste that will be removed from

the floodways, canals and retention basins that are being dredged by this project will be disposed of in the following manner .

• Non-Hazardous Sediment Material - will be transported and disposed of at the Ancol Sea Reclamation Works, known as the Ancol confined disposal facility (CDF). The project will not incur any charges for disposing the material at the CDF.
• Hazardous Sediment Material (if any are found) - will be disposed of at the PPLi Hazardous Waste Facility in Bogor,

8 West Java . Disposal at PPLi is subject to a disposal fee, funding for which is included in the JUFMP dredging contract.

• Solid Waste - will be transported and disposed of at City of Jakarta's landfill in Bekasi, West Java, known as the Bantar Gebang Landfill. Disposal at Bantar Gebang Landfill is subject to a landfill tipping fee, funding for which is included in the JUFMP dredging contract.

  7 The exact methodology and equipment for transportation will be proposed by the works contractor, subject to the approval of the Supervision Consultant. The bidding document specifies the minimum parameters to be adhered to by the contractor.

  

8 Note that specific proposed method to treat/dispose of any hazardous waste will follow national regulations on hazardous waste treatment and disposal and subject to the approval of the Ministry

of Environment (MoE).
