Issues And Expected To Technologies In Water Infrastructures - Indonesia is an archipelago comprising approximately 17, 508 islands and 70% of total areas of Indonesia are coastal areas. This condition has made the coastal areas has limited access to water supply. The water treatment plant that can produce drinking water from sea water or brackish water are definitely is expected to solve the water supply problem for coastal regions and small island, especially with the low energy consumption to reduce operation cost - Urbanization has created many activities which produce pollution to water resources. Thus increasing the demand of water supply and degrading the water quality resource. Therefore, the advanced technology for high turbidity of raw water is needed.
Issues And Expected To Technologies In Water Infrastructures - The rural communities live in many remote areas in rural, with problem of energy to operate the water supply system. The technology of solar cell needs the complex maintenance, which cannot be operated well by the community and difficult to find spare parts. Therefore some technologies that is simple, low cost energy is required by rural communities - The community in some places in Indonesia lives in the swamp area with of humic raw water resources with colour. Now we provide in rural area by the conventional treatment plant with small capacity. Some areas have already been developed as an urban area with high demand for drinking water. Therefore, the water treatment plant with big capacity is needed
WATER SUPPLY OPERATORS Local water supply enterprises / Water Operators (PDAM) Capacity Number of PDAM Service Coverage (%) > 3,600 m3/h ( > 1,000 l/s) 3,600 m3/h 1,800 m3/h ( 1,000 l/s 500 l/s) < 1,800 m3/h) ( < 500 l/s) Total capacity (m3/h) 529.210,8 23 > 60% : 13 < 60% : 10 36 > 60% : 9 < 60% : 27 286 > 60% : 35 < 60% : 247 Total PDAM: 341
ISSUES AND EXPECTED TO TECHNOLOGIES IN WATER INFRASTRUCTURES WOPs (Water Operator Partnerships) Collaboration between mentor (well run waterworks) with recipient (local waterworks) in particular agreed subject for certain period of time twinning Subject of interest: - NRW reduction - Energy efficiency - Asset management - Technical management - Financial management, etc.
ISSUES AND EXPECTED TO TECHNOLOGIES IN WATER INFRASTRUCTURES REDUCTION OF THE NON REVENUE WATER The term is related to the effort on reducing the Non Revenue Water (NRW) in water supply operator The subjects is the level of NRW to be reduced Pre-condition: Water Supply Operator with NRW > 40%; Supply coverage > 80% population Full cost recovery tariff
ISSUES AND EXPECTED TO TECHNOLOGIES IN WATER INFRASTRUCTURES ENERGY EFFICIENCY The term is related to the effort on reducing the energy consumption in particular equipment as to the efficient one The subjects are the apparatus of the water supply system which consume energy to operate. This includes the electrical and mechanical equipment. Pre-condition: Water Supply Operator with energy consumption > 30% of the operational expenses; Full cost recovery tariff
Performance Base Contract The implementation of NRW reduction and energy efficiency use Performance Base Contract which means The contract agreement between a water supply operator (waterworks) with a private partner based on the performance achievement of the partner to meet the goal of NRW reduction or energy efficiency which is set up, first in the beginning
Issues and Expected Technology In Wastewater Sector A city wide sewerage system requires high investment cost, the needs for approriate technology for tropical climate with a relatively low in operation and maintenance costs have never been more urgent
Issues and Expected Technology In Wastewater Sector ISSUES AND EXPECTED TO TECHNOLOGIES IN WASTE WATER INFRASTRUCTURES Indonesia have 150 septage treatment plants, with 90% of the units are not working properly due to: - Institutional problems - Most of the treatment are not in adequate conditions - Low loading input to the treatment system because of: Bad quality of septicktank (not waterproof) resulting in no sludge to be desluged by the transporting unit Ilegal direct desludging to the water body
Issues and Expected Technology In Wastewater Sector Lack of awareness towards sanitation, especially in slum areas and low income communities Low cost technologies needed, which are easy in maintenance and bring out participation of low income community in slum urban areas.
ISSUES AND EXPECTED TECHNOLOGY IN STORMWATER/DRAINAGE INFRASTRUCTURES Package C1 & C2 Semarang Pumping Station and retarding Pond Indonesia has about 496 cities, some of the cities located in coast side which is vulnerable of Rob flood presence. Some issues considered by the government are: a. The land subsidence affected by an enormous groundwater exploitation. b. Numbers of metro cities establishment and development lead to an increase of run-off that contribute the stormwater load to the drainage. c. Changes of rainfall pattern suspected caused by the climate change.
ISSUES AND EXPECTED TECHNOLOGY IN STORMWATER/DRAINAGE INFRASTRUCTURES Banda Aceh Retarding Pond Today and future, there would be an increase establishement of polder system especially in coast side cities and river delta cities to overcome rob flood. Retarding Pond and Large Capacity Pump Station also progressively required to overcome flood matters.
ISSUES AND EXPECTED TECHNOLOGY IN SOLID WASTE INFRASTRUCTURES Solid waste collection service coverage still low (60-75) % No waste separation source Final waste disposal still open dumping (90%), only a few that has been upgrade to sanitary landfill The development of sanitary landfill to substitute the open dumping is required to implement CDM
ISSUES AND EXPECTED TECHNOLOGY IN SOLID WASTE INFRASTRUCTURES Final disposal area in metropolitan and big cities usually more than 10 Ha The tickness of waste pile varies with an avarage more than 10 meter Methane gas released directly into air due to no gas treatment facilites The development and improving the quality of landfill by applying technology landfill Gas Flaring and energy generation
