Teguh Hendarwan, Head of Jakarta Water Resources Dept. said, this year, his dept. has mapped normalization work in five cities, especially areas flowed by 13 rivers.

"The project has reached 80 percent. Because it has been ongoing since the beginning of this year," he expressed, Tuesday (9/26). 

He mentions, in South Jakarta, it is centered in Krukut River and Mampang area. There are also Sunter River and Ciliwung River in East Jakarta, Moekervart River and Pesanggrahan in West Jakarta.

"Not only that, there are also Sunter River and Ancol River in North Jakarta and tributary of Ciliwung in Central Jakarta. It is done in self-managed," he stated.

Nevertheless, there are found some problems. One of them is difficulty of heavy equipment mobilization to the location and illegal buildings on the riverbank.

"Maximum dredging can only be up to two meters depth. Even, the buildings on the riverbank can potentially lead to landslid e," he closed.
