5. Concluding Remarks

In conclusion the water supply for all utilities in the reclamation land covering 2700 Ha must be provided from the resources other than groundwater. Such that the study to get the ultimate goal should be done comprehensively. How much water demands on the future reclamation land, and which surface water will provide most benefits. Referring to the C-5 scenario proposed by JWRMS, 1994, the water demands may probably be provided from Tarum Barat Channel (4.9 m³ sec^-1). Channel 2 (31.2 m³ sec^-1) is developed to distribute water from Jatiluhur Reservoir, and Serpong Channel (6 m³ sec^-1), at the time where the total water demands in Jakarta being 42.1 m³/second in 2025.

Meanwhile the impact of land reclamation on the groundwater should be studied, whether any impact on the drainage pattern, availability and quality of groundwater in the whole Jakarta Basin.

Those efforts should be coincided with the increase of PAM Jaya roles. The progressions which have been reached to increase the service accessibility of PAM Jaya is still far from being proposed. Due to the groundwater resources as a raw materials for the water supply in the reclamation land can not be relied, such that management development for PAM Jaya is being important to be able in providing water supply for the reclamation land.

Programs being proposed by Kirmanto, 1995, through the co-operation with the private company, probably can be adopted to empower the performance of PAM Jaya to provide water in the reclamation land.
