Effort

To minimize the impacts due to urban and industrial development to the groundwater, efforts has been made both from legal and technical aspects.

Recommendations for primary land use from the environmental geology point of view have been submitted to local government. Those recommendations among others contain which parts of the Greater Bandung should be protected its groundwater quality, where is proper waste disposal site should be located and recommended for foresty areas. Local government put these recommendations into consideration of spatial planning of the Greater Bandung and try to applied it strictly. In order to increase recharge rate to the basin, buy law it is obliged to new building to build shallow recharge wells, which collects rain water from roof catchment.

To reduce groundwater usage by industry, some parts of the Greater Bandung area since December 1993 have been decided as restricted from new abstraction of groundwater for industrial purposes.

There is a plan to increase of surface water usage for industries by building new small dams in the Citarum river tributaries. By 2005, the usage of groundwater for industrial purposes will be reduced to 32 million m³, while the usage of surface water will be increased to 146 million m³. Other option is to relocate industries to the Cililin industrial park, which will be located nearby source water, Saguling dam, in west of the basin, which will supply about 44.3 million m³ by 2005 (Anonymous, 1996).
