Total amount of Jakarta population in
2017 are 10.4 million persons.
Population growth is linier with clean
water consumption and cover area.
Hence, recharged water to aquifer will
decrease.

Land Subsidence Map in DKI Jakarta 2014 – 2017 monitor by GPS
The results of monitoring, in 2017 the severe land subsidence isaround Pulogadung, Tanjung Priok, Pademangan, Pluit,Penjaringan and Kembangan with the maximum 25 cm inbetween 2014-2017 (3 years)
