Presentation to CCFBy Philippe Wind, Technical Director

PALYJAJUNE 2007


PALYJA – Water Concession Company established in 1998 for west

Jakarta• Private company, 50% Suez Environnement, 50% Astra• Under concession contract with DKI, managed by PAM• Full scope of service:

– Water treatment, distribution pipes Network, customer– Deliver water to the people connected– Standard “air bersi”

• Money collected used to pay all water costs:– 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 supplyA minimum pressure above 7,5 M at connection level will lead to continuous supply and bring strong improvement in reduction of commercial losses.


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


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 partiesContinuation of investment is needed

Impact on medium term will be significant for population health and

well beingThank You !
