Due to the impact of the 1997 East Asian financial crisis the contracts were renegotiated in 2001 and the Water Supply Regulatory Body (JWSRB) was established as an "autonomous" regulator in charge of supervising the concessions on behalf of the Governor of Jakarta and the Ministry of Public Works. Since early 1998 the water rate has increased by 15% in February 1998, 35% in April 2001, 40% in April 2003 and 30% in January 2004 in nominal value prices. The inflation rate in Indonesia was 12% in 2003, 6.6% in 2004, 6.1% in 2005 and 10.5% in 2006. More frequent tariff increase had been contractually scheduled to finance needed investments and to compensate for inflation. However, Jakarta Governor Sutiyoso and the City Council had refused to raise water rates according to schedule, thus forcing the two concessionaires to cut down on investments.
In 2004 a consumer group sued the concessionaires for providing poor services. The lawyers of the utilities rejected the claims saying that the evidence presented was poor and that a survey to support the claims was not carried out by an independent agency.
In early 2004 a regular increase of tariffs every six months between January 2004 and 2007 was agreed. Subsequently investments picked up again, focusing on replacing the decrepit distribution network.
