The city administration says it will improve Jakarta's flood management system to tackle floods caused by rain, high tides and global warming.
"We will soon upgrade the existing flood management system making it suitable for our present environmental conditions," Governor Fauzi Bowo said Wednesday.
Fauzi said the administration had built embankments to deal with high tides but said they were only a short-term solution, as Jakarta's flood management system needed to be able to respond to global warming.
He said the administration would improve the dam system, which pumps water in the city out to sea or into canals throughout Jakarta.
"The Netherlands, for example, which has a lot of land beneath sea level, uses pumps to expel water back to sea which come on automatically if the sea level changes ... We haven't applied such a system yet," Fauzi said, as quoted by Antara.
A 2.2-meter-high tide submerged Pluit and Penjaringan subdistricts Monday, disrupting traffic and forcing residents to flee their homes in North Jakarta's coastal areas.
Fauzi said the city administration, through the Public Works Agency, would renovate several embankments in areas affected by the tides.
Previously, head of the Public Works Agency's water and coastal resources management unit, I Gde Nyoman Soewandhi, said the floods in North Jakarta were caused by the damaged Pluit and Muara Baru embankments which could not hold the high tide back.
Nyoman said Monday some 20 meters of the Pluit embankment was damaged due to the high tide. The Public Works Agency repaired the embankment using river stones reinforced with iron and sand sacks, but on Tuesday said other parts of the embankment had also burst.
According to Nyoman, the damage was related to the age of the construction -- almost 20 years.
In 2007, the administration allocated money from the budget to renovate and raise the Muara Angke embankment by 30 centimeters.
"We can't delay the construction. We must raise Pluit and Muara Baru embankments by next year, otherwise city dwellers living nearby will be in danger," he said.
The Central Jakarta administration is currently restoring river embankments to anticipate floods at the peak of the rainy season in December.
"The work is part of Fauzi Bowo's first-100-days agenda," Mayor Muhayat said.
The river embankments being restored are near Jl. Teuku Umar, Jl. Diponegoro (opposite Cipto Mangunkusumo Hospital), Jl. Cikini Raya, Jl. RP Suroso and Jl. Cempaka Putih Indah, to name a few.
Some 10 areas prone to floods in the municipality are Matraman Dalam, Kali Pasir Kwitang, Kebon Kacang, Pejompongan, Jati Pinggir, Karang Anyarm, Mangga Dua, Gunung Sahari, Serdang and Cempaka Putih.
