Abstract


The rapid development of many sectors at the Bandung-Soreang Groundwater Basin has increased the
demand for clean water. It is estimated that approximately 70 per cent of the clean water demand is still
fulfilled by ground water. In the last five years, the use of ground water from deep and dug wells has shown a
tendency of increase. In 2001, total use of groundwater reached 46.6 million cu m, and in 2005 had increased
to 51.4 million cu m. The increasing use of ground water at middle aquifer and deep aquifer has intensified the
depth of ground water level. A distribution of ground water level decrease at middle aquifer was observed at
some areas in West Java, i.e. South Cimahi 91.0 m bgl; Dayeuhkolot 62.0 m bgl; Rancaekek
Cimanggung 68.0 m bgl; Majalaya 43.0 m bgl; and the city of Bandung 62.9 m bgl. The depth of ground
water at deep aquifers at areas such as, South Cimahi, Dayeuhkolot, Cikeruh and Rancaekek varied between
24.7 - 68.2 m bgl. Between the years of 2000 and 2006, at middle- and deep aquifer respectively, the decrease
of ground water level showed a rate of 0.11 12.03 m/year and 0.16 2.61 m/year.
