Abstract
Sewerage service population in Jakarta is only 2.62%. Direct discharge of domestic wastewater and improper design and installation of septic tank cause pollution to river and groundwater. However, these pollution has not been evaluated in detail. This research is aimed on the analysis of the existing condition and tendency of river and groundwater quality. As a result, in rivers T-coli, COD, BOD, NH4-N, surfactant, PO4-P, and oil/fat exceed the standard relatively. On the other hand, in groundwater the parameters exceeded the standard largely are T-coli, NH4-N and Fe. In addition, the water quality improvement was suggested by the basis of water quality condition and the water environmental policy of Indonesian government. As a suggestion, manpower development is required at first. Then suitable programs or projects should be prepared and executed.
