However, even if the upstream area of the Ciliwung been free of the villas , it has completed the third of flooding problems .
The provincial government of Jakarta Special Capital Region seeks to prevent flooding by adopting several measures , including working with the provincial government of West Java , Bogor district specifically to evict illegal villas in Puncak area .
In the past week , Civil Service Police Unit unload 41 villas in Puncak area , because it does not have a license and violate the rules because it is built on water catchment areas and protected forests .
Environmental expert of the Board of Forestry and Environmental Observer Tatar Sunda Sobirin explains , there are three main causes of flooding in Jakarta that need fast handling , not only by the Government of Jakarta , but also in West Java , Banten and the central government .
" The cause of the flood is a flood of submissions is on the upstream side of the upstream Cilegung , south of Bogor , and also from the Cisadane river upstream . Then the second is the drainage ( water channels ) in the city itself , " he said .
" Drainage of Jakarta was as yet perfectly true . The third is , when the season full moon and new moon was rising tides and sea water and the water is turning back to close the river . "
Sobirin welcomed the cooperation among local governments in conducting evictions villas built over the water catchment areas .
" Eviction villas are quite nice as lessons on spatial irregularities that had been done . That area is a protected area that is based on rainfall slope and soil type , the area should not be actually built . So in this case the spatial planning law enforcement to be there , " he said .
However Sobirin added , if the upstream area of the Ciliwung is free from the villas , the completion of a third new flooding in Jakarta . Because according to two-thirds of the flooding problems in the capital Jakarta alone , the drainage problem and security of the sea tide north of Jakarta .
Jakarta Vice Governor Basuki Purnama T previously explained , Jakarta administration Rp 2.1 billion to help dismantle the illegal villas .
In addition , Bogor regency will also get help to repair watersheds ( DAS ) and community development as well as the normalization riverbank reservoirs , such as Ciliwung River and the upper reaches Situ Cikaret . The second area is an area of the reservoir and distribution of water during the rainy season .
