The document discusses the water supply system in Jakarta, Indonesia. It notes that Jakarta receives its raw water from the Jatiluhur Dam (81%) and internal sources within Jakarta (3%), with the remaining 16% coming from treated water from Tangerang. It describes the existing water production and distribution infrastructure, including various water treatment plants and canals. It also outlines constraints such as limited water resources, high non-revenue water, and the need for infrastructure upgrades. Finally, it discusses policies to address these issues and develop the water supply system to meet growing demand.

4. WATER RESOURCES IN JAKARTA
Jakarta is passed by 13 major rivers. There are some reservoirs or lakes spread around of Jakarta
area, but the most of resources can not be used as raw water for drinking water due to:
•Most of rivers and reservoirs water quality is bad
•Critical capacity, especially in dry season
•Unstable continuity

9. WATER RESOURCES ADDITIONAL PLAN
Total existing
capacity of water
production is
18.025 lps (2013)
To Achieve MDG’S (68%
coverage ratio in 2015)
and Zero Deep Well, it
require the additional
supply about 8.000 lps –
10.000 lps.
Additional supply
plan (will be
implemented in
2014 to 2016) is
about 5.700 lps
BTW supply reduction to
800 lps, stagging to 2022.

10. WATER SUPPLY DEVELOPMENT PLAN

11. CONSTRAINTS IN WATER SUPPLY DEVELOPMENT
• Limited of availability of water resources caused service
coverage and service level is not optimal.
• The level of NRW is high (41,47%)
• The Management of NRW Reduction is not optimal and
comprehensive.
• The condition of urban infrastructures is complex, the
integrate of utility networks laying.
• Development of new WTP, network development and
networks arrangement require high investment.
• Deep well consumption.
• Exclusive Right of Private Partners

12. POLICIES IN WATER SUPPLY SYSTEM
DEVELOPMENT
• To develop any alternative study programs for increasing water
security in Jakarta, either short term and long term, such a study of
potential water resources in Jakarta area.
• To encourage the implementation of additional raw water/treted water
acceleration, either short term and long term
• To provide a Master Plan of Water Supply Development for Jakarta.
• To reduce the NRW level, either commersial losses and physical
losses.
• To increase the Service Coverage Ratio optimally and proportionally.
• To develop services that meet the minimum service standards
• To develop water supply for the Low-Income Communities area.
• To do strict supervision of the implementation of cooperation to
improve the performance, revenue, and to reduce the deficit
cooperation projects.
