– water resources
– operating costs
– Investments
PALYJA employs directly 1400 people, serve 380 000
accounts for around 2,5 million people. Produce 700
000 m3/day to deliver continuous supply at above 7,5 M
of pressure. PALYJA invest around 20 mio USD/year.

Losses and continuity of service
• Commercial losses is a big part of total losses
• Lack of continuity of service strongly degrade
commercial losses as:
– Unhappy customer may seek for illegal connection
– Customer may modify his installation to get more
water and affect or bypass metering
– Management has more difficulties to differentiate
metering and bill anomalies from lack of supply
A minimum pressure above 7,5 M at connection level
will lead to continuous supply and bring strong
improvement in reduction of commercial losses.
PhW / Palyja / June 07
Water Quality and Drinking water
objective
• Drinking water status cannot be fulfilled without the
preliminary conditions :
– Full time pressurized network
– Decrease of physical losses
– Sufficient production facilities in stand-by to
provide treatment process improvement
(All these conditions are related to avoid
contamination of the network)
– Constant raw water quality
PhW / Palyja / June 07
Key issues for future
• estimated 20% water deficit between supply and
demand.
• Reduction of physical losses not enough to cover the
deficit, commercial losses represent water consumed.
• strong need to bring additional water resources to meet
water demand
• Increase in resources will lead to better continuous
supply that will improve quality and reduce losses
• several possibilities to get additional resources to
improve water service and meet demand for Jakarta

Conclusion
PALYJA is planning and implementing
necessary actions to improve service,
quality and coverage for west
Jakarta.
Additional water resources are
necessary but are possible with
involvement of all parties
Continuation of investment is needed
Impact on medium term will be
significant for population health and
well being
