‘Post-concession’ water supply in Jakarta
In 1997, the water supply of Jakarta was divided up and assigned to two private companies - PT Aetra in the east and PT Palyja in the west. The private companies operated the water treatment plants and the distribution network in the areas allocated to them. PAM Jaya, the state utility, paid the companies a ‘water charge’ based on the volume of water the private companies supplied to households. The Jakarta government covered the ‘shortfall’ between the water charge and the tariff collected from users.
At the start of the contract in 1997, around 50% of the population in Jakarta had access to piped water supply, and 56% of the treated water was lost because of leakages and illegal use (‘non-revenue water’).3 In the 25-year contract period, the private companies were supposed to improve the distribution and provide piped water supply to the entire population. However, at the end of the concession contracts, the situation had not improved significantly.
According to official data, at the end of 2022, the service coverage had improved only to reach 60.79%, and the non-revenue water remained at a very high level of 46.66%.4 Over the contract period, the companies steadily drew high annual revenues (with an internal rate of return of 15.68% over 25 years) but invested very little in developing or maintaining the water supply infrastructure. Studies have found that water supply expansion and improvements have been concentrated in higher income settlements, while the urban poor found themselves economically, politically and socially ‘disconnected’ from access to piped water supply.5
