JAKARTA CAPITAL CITY ADMINISTRATION Grey Solutions for Urban Water Management : JAKARTA Case Feirully Irzal, MBA Presented on “C40 Workshop on Senior Planner – Infrastructure Division Climate Adaptation and Risk Assessment “ Regional Development Planning Board Jakarta Capital City Administration Rotterdam, The Netherlands INDONESIA June 3‐6, 2013 OUTLINE • FACTS AND PROFILE • MAJOR ISSUES • WATER RESOURCE ISSUES • JAKARTA FLOOD MITIGATION CONCEPT • CURRENT AND FUTURE INITIATIVES OF WATER RESOURCE MANAGEMENT • CONCLUDING REMARKS FACTS AND PROFILE OF JAKARTA Basic Social ‐ Economic Role DKI Jakarta administration area: miniature of Indonesia Capital city • 5 Municipalities and 1 regency Very contrast social status of its National Activity Centre for • 44 districts citizen: Economic, Business and Service • 267 sub district/village •Wealthiest vs poorest Communication hub for Indonesia Area : approx 650 KM2 •Most educated vs most uneducated Tourism City Population: Multi ethnic and very heterogenic Cultural City • Approx. 9.5 million (night time) Economic growth 2012 6.5% • Approx. 13 million (day time) Centre for Higher Education • Density approx. 14.000/km2 Forecasted to be competing with Singapore, Kuala Lumpur Bangkok, Jakarta and its surrounding cities form and Ho Chi Min City as centre for Metropolitan area Jabodetabek, business and trading. population : approx. 25 million Greater Jakarta (Jabodetabek) MAJOR ISSUES OF JAKARTA • Volume of solid waste in 2008: 29.364m3 / day EnvironmentEnvironment • Air pollution • Water pollution: concentration of DO, Ni, Cu, Zn, Hg above standard • Rise of sea level • Land Subsidence • Destruction of Conservation Area on the ground, coastal side, sea and islands • Lack of Green Open Space • Flood caused by backwater, river flooding, clogged drainage system WaterWater ResourceResource • Low quality and quantity of clean and raw water especially in north Jakarta • Limited coverage of piped wastewater network • Excessive extraction of groundwater that causes land subsidence • Intrusion of sea water WATER RESOURCE ISSUES Jakarta‘s geographical and topographical setting as a Delta City makes it vulnerable to flood problems, this is dueKEPULAUAN to: SERIBU KEPULAUAN SERIBU •Traversed by 13 rivers to Jakarta Bay •Part of Northern Jakarta lies in lowlands and frequently influenced by tidal condition causing backwater. LOW LANDS 13 RIVERS This condition is exacerbated by external factors: 1.Climate change: sea level increase and changes in rainfall intensity and pattern 2.Continuous land subsidence at a rate of as much as 10cm/year in certain part of north Jakarta Land subsidence 1991‐1997 Rainfall Pattern in Jakarta, 2010 Source: Susandi, 2010 PHOTOS OF URBAN WATER ISSUES JAKARTA FLOOD MITIGATION CONCEPT PREVIOUS CONCEPT CURRENT AND FUTURE Tanggu l 3 CURRENT & FUTURE INITIATIVES FOR FLOOD MITIGATION CURRENT INITIATIVES 1. Completion of East Flood Canal construction 2. Construction of interconnection between West Flood Canal and East Flood Canal 3. Dredging and normalisation of vital flood canals/rivers/lakes/polders under the Jakarta Emergency Dredging Initiative Project 4. Reconstruction and capacity improvement of pumps 5. Construction and heightened of sea embankments to anticipate the increase in sea level rise and land subsidence in North Jakarta. 6. Resettlement of illegal housing along rivers/lakes and river widening FUTURE INITIATIVE Preparation of Sea Defense Wall Master Plan to protect the Northern Jakarta from inundation caused by increase in sea level and continuous land subsidence. The development will also create momentum for urban redevelopment of Northern Jakarta. CURRENT INITIATIVES JEDI (JAKARTA EMERGENCY DREDGING INITIATIVE) • The project is a cooperative effort between Central and Jakarta Government to dredge and rehabilitate 13 rivers and 5 reservoirs in Jakarta to reduce the impact of flood. • Flood area will be reduced from 203 Km2 (in 2007) , to only 144 Km2 (30%) • Current work ongoing: • Tender preparation • Land acquisition and preparation for resettlement • Preparation of Sludge Disposal Site, located in Ancol North Jakarta. CURRENT INITIATIVES JEDI REDUCING FLOODED AREA FLOOD 2007 AFTER DREDGING Flood area 203 Km2 Flood area 144 Km2 CURRENT INITIATIVES EAST FLOOD CANAL BANJIR KANAL TIMUR • 23.5 km Canal (flow from east to north Jakarta) with water catchment area of 20.125 Ha, expected to reduce 26 spots of flood area (from before 78 spots) and prevent flood for Industrial and Residential Area in East Jakarta (15.401 Ha). The momentum is also leveraged not only for flood control but for redeveloping and redesigning the area, increasing city green open space and supporting the supply of clean water. FUTURE INITIATIVES National Capital Integrated Coastal Development (NCICD) In year 2010 In year 2030 In year 2050 66.355 x 106 m2 131.914 x 106 m2 187.997 x 106 m2 Or 10.26% of area Or 20.41% of area Or 29.09% of area Below the sea Below the sea Below the sea Source: Study of Jakarta Coastal Defense Strategy Strategies 1.Minimise land subsidence by: • Limit the ground water extraction • Provide sufficient supply of raw water from surface water • Develop water retention basins 2.Develop Sea Defense Wall (NATIONAL CAPITAL INTEGRATED COASTAL DEVELOPMENT/ NCICD) NATIONAL CAPITAL INTEGRATED COASTAL DEVELOPMENT • Stage 1(Protection until 2020): – Short term coastal protection • Stage 2 (Protection until 2030): – Integrated sea dyke construction with new land reclamation • Stage 3 (Protection beyond 2030): – Construction of multi‐purpose sea dyke at Jakarta Bay NCICD INVESTMENT OPPORTUNITIES 1. New land reclamation (approx. 5000ha) in between the existing coastline up to ‐8m depth 2. Water recreational facilities, water trasportation, fisheries, raw water reservoir, etc 1. Deep Sea Port in between the outermost dyke (dyke 3 at approx. ‐ 14m depth) and the new land reclamation dyke (dyke 2) NCICD INVESTMENT OPPORTUNITIES 1. Access road (4 lanes) on top of the dyke along the existing coastline 2. Toll road (10 lanes) and double‐ track railway line on top of the dyke along the reclamation area. This function as connector of airport, sea port and industrial areas. 3. Toll road (10 lanes) on top of dyke at approx. 6km off‐shore from the existing coastline . This function as East ‐West by‐pass and form part of the Merak – Surabaya National Toll network NCICD OFFERS INTERESTING PPP OPPORTUNITIES ¾ Coastal Defense Infrastructures and additional Coastal Additional Investment measures that are non‐profitable (‐) require public Protection Measures Opportunities financing (Local/state budget). Investment Sea Dyke & River Water Reclama opportunities that are profitable (+) may be funded by embankm supply tion ent private sector through PPP ¾ Based on Cost‐Benefit Analysis, partial investment on individual project is less financially viable. However if those projects combined and integrated would result Polder Waste and Toll in a more attracted investment package that is Water & Retention Road strategic and financially feasible. Pond Sanitati on ¾ Moreover, the Integrated Coastal Development solution not only protects the Northern Jakarta from inundation, but it also offers solution to the problems Pump of raw water supply, river pollution and traffic Stations Deep Sea Port congestion in the city. ¾ Flood protection combined with land reclamation, infrastructure development and urban renewal, is expected to transform Northern Jakarta into a more attractive place for investment, living and working. CURRENT PROGRESS OF NCICD - Masterplanning Phase (2013 – 2014) 1. Strategic concept review of Jakarta Coastal Defense Strategy to synchronize with other masterplans 2. Detailed concept design of coastal protection 3. Pre‐ design, pre‐Feasibility Study and Strategic Environmental Analysis 4. Cost estimate, Cost‐Benefit Analysis, funding schemes 5. Detailed stages of development 6. Preparation of Legal Framework for NCICD Masterplan as a basis for implementation and invesment CONCLUDING REMARKS 1. Jakarta is faced with environmental problems, such as deteriorated surface water quality, shortage in raw water supply, land subsidence, urban flood and tidal flood, especially in the northern Jakarta 2. Integrated Coastal Development concept offers a breakthrough solution that does not only provide protection to the north Jakarta from flooding, but also function as raw water reservoir and creates opportunities for investment in toll roads, Railway, deep sea port, land reclamation, and urban redevelopment of north Jakarta. 3. There are plenty of endeavors need to be done for the implementation of NCICD, that require stakeholders participation (community, Government and private sectors) JAKARTA CAPITAL CITY ADMINISTRATION THANK YOU.
