Jakarta needs 200,000 more absorption wells to secure water storage

Jakarta(RRI)-Jakarta needs to build more than 200,000 absorption wells to help the city maintain its groundwater level and secure water storage for future needs, an official from the Forestry Ministry says. According to our studies, Jakarta should have 261,852 absorption wells to ensure it has enough groundwater in the future,” the ministry’s watershed management director Silver Hutabarat said in a discussion Friday. 

But unfortunately, we currently have less than 3,000 [absorption wells]. Once all the wells are built, Silver said it would help the city absorb a total of 437.2 cubic meters of rain water per second, or equal to the water stream capacity of city’s West Canal.

But the difference is the canal takes rain water to the sea,” he said. The Jakarta Environmental Management Agency (BPLHD) reported that the city lost 65.8 million cubic meters of its groundwater annually, mostly because the ground in Jakarta absorbs less water than the amount it should, decreasing its groundwater level. The decline of groundwater also causes land subsidence.
