1. Introduction

Greater Jakarta area will soon extend 2700 ha more, through reclamation of Jakarta Bay. There was a great discussion on that reclamation planning among the experts, concerning the impacts to various aspects of environment, physical and social such as flood, coastal abrasion, changing of sea current, and social impacts. However, focused on water supply in reclaimed land afterward and relation to groundwater resources is still lacking.

As the reclamation planning is becoming political will of the government, is to be an obligation for expersts on their own field respectively, to contribute those planning in order to minimise any negative impacts which might be happened.

The authors are not pretending to be an expert, however, based on our knowledge which we have, the paper intend to give inputs to the decision makers, particularly from groundwater conservation perspective, what anticipation should be taken, hence, the reclamation is still keeping groundwater resources in North Jakarta sustainable, or even better than the present time. Since we don’t have any access to detail planning of the reclamation, all impacts and anticipation which are described in this paper, are merely based on hypothetical background.

The addition of land in North Jakarta will give logical consequences on increasing demand of water supply in the reclaimed land. The modern business centers, appartments, housing complexes, and other public utilities which will be build in the reclaimed land, will need a lot of water and increase water supply in Greater Jakarta correspondingly.

Since the existing land and population of Greater Jakarta at present are still highly relied on groundwater, therefore the water supply for reclaimed land will be a crucial part of the development of the land. Its development relates to water supply should avoid any increasing degradation to the groundwater resources of Jakarta basin, particularly in the northern part.
