Jakarta still has a long away to go to provide its own sustainable clean water. According to head of the Jakarta City Development Planning Agency (Bappeda) Tuty Kusumawati, about 90 percent of the city's raw water comes from outside Jakarta ' 80 percent from West Java and 10 percent from Banten.
'Only 10 percent of our raw water comes from Krukut River and Pasanggrahan River [both in Jakarta province]. Meanwhile, 10 percent comes from Tangerang [in Banten] and 80 percent comes from Jatiluhur dam [in West Java],' said Tuty as quoted by kompas.com on Tuesday. The raw water is then treated to turn it into tap water.
She was speaking on the sidelines of a workshop on sustainable urban water management in Jakarta on Tuesday.
Recently, Jakarta Governor Basuki 'Ahok' Tjahaja Purnama shared his ambition to clean up Jakarta's rivers, particularly the longest one, the Ciliwung River, to reduce the city's heavy dependence on water from other provinces.
There are 13 main rivers in the capital, which flow from West Java and Banten. Unfortunately, the water in most of those rivers, according to tap-water producers, is so dirty because of domestic and industrial waste it would not be economically viable to treat it to make tap water.
Therefore, Tuty stressed, the declining water level in the Jatiluhur dam, located 110 kilometer from Jakarta, particularly during this long dry season, was seriously affecting raw water supplies in the capital.
Currently, the city-owned PT Pam Jaya cooperates with two private water operators ' PT PAM Lyonnaise Jaya (Palyja) and PT Aetra Air Jakarta (Aetra) ' to meet the clean water needs for less than 60 percent of the city population. The other 40 percent meanwhile, still rely on groundwater. (bbn)(+)
