ABSTRACT
Goundwater resources played an important role in supporting development in Jakarta and Bandung. Both cities have two main groundwater management instruments, legal and technical. However a number of factors including, continuously increasing water demand which is highly reliant upon groundwater, a rising population, changes of land usage, partial and sectoral management, weak law enforcement, and low awareness of the need to manage groundwater in a sustainable manner has made management ineffective and led to the degradation of groundwater resources in both cities. Efforts have been made in both cities, which appear to have achieved promising results, in reversing this degradation.
