Jakarta. Indonesia's Public Works and Housing Ministry is building two dry dams in Bogor, West Java — Bendungan Ciawi and Bendungan Sukamahi — expected for completion in 2019 to try to prevent flood in the capital Jakarta, which is often caused by heavy rainfall on its outskirts.
Bogor, nicknamed "rain city" because of its higher-than-average rainfall, often sends a great amount of water to Jakarta through the Ciliwung River in the rainy season, causing minor dams to burst and massive floods in the capital.
Bendungan Ciawi and Bendungan Sukamahi are just two of 65 new reservoirs planned by President Joko "Jokowi" Widodo's administration to prevent floods all across the country.
Bendungan Ciawi covers an areas of 29.22 hectares and will cost Rp 757.8 billion to build. Bendungan Sukamahi covers an area of 5.23 hectares and will cost Rp 436.97 billion.
"These two dry dams are part of Jakarta's flood control system to contain water flows from Mount Gede and Mount Pangrango to the Ciliwung River. When there's heavy rain in the mountains, the dry dams will control the volume of water released to Ciliwung," the ministry said in a statement on Wednesday (13/12).
The dry dams will only be filled with water during the rainy season. They will stay empty during the dry season.
"President Jokowi is scheduled to inspect progress on the dams soon. I've told the contractors to speed up their work," Public Works Minister Basuki Hadimuljono said in Bogor on Tuesday.
