This document discusses issues around water privatization in Indonesia. It notes that several NGOs asked the Constitutional Court to revoke the 2004 Water Resources Law due to concerns about privatization. There is debate around how opaque the rules are regarding private sector participation in water services. While the law allows for some private involvement, the implementing regulations are unclear, such as whether it is limited to new "greenfield" projects. Examples from Jakarta, Bogor, and Batam show problems with neglected private contracts and lack of regulation of monopolistic practices. The document concludes that while laws like the Public Service and Freedom of Information Acts have potential to improve regulation of private sector participation, reforms are still needed for effective oversight.
