The Jakarta provincial government is expanding groundwater-free\nzones. PAM Jaya\u2019s director general Arief Nasrudin has stressed that\nhigh-rise buildings already supplied with water from the PAM network\nshould no longer use groundwater.<\/p>\n
\u201cHigh-rise buildings that already have water supplied from PAM should\nstop using groundwater. We must enforce this,\u201d Arief said at Jakarta\nCity Hall on Wednesday (11 March).<\/p>\n
According to Arief, expanding groundwater-free zones is important\nbecause piped water service coverage in Jakarta has reached\napproximately 80\u201382 per cent, making it timely to significantly reduce\ngroundwater dependence.<\/p>\n
\u201cThis is what we\u2019re advocating to Jakarta\u2019s provincial government\u2014to\nexpand groundwater-free zones. Because our service coverage has already\nreached over 80 per cent this year,\u201d he said.<\/p>\n
He cautioned that excessive groundwater exploitation can cause\nserious environmental damage, particularly land subsidence, which has\nalready occurred in various regions. Arief cited several Indonesian\ncities experiencing ground subsidence due to uncontrolled groundwater\nuse.<\/p>\n
\u201cMany cases are happening now. Land keeps sinking. In cities like\nSemarang and Tegal, the effects are already being felt,\u201d he noted.<\/p>\n
He argued that providing adequate clean piped water is a fundamental\nrequirement if Jakarta is to genuinely transform into a global city.<\/p>\n
\u201cIt\u2019s odd to talk about being a global city when we haven\u2019t even\nsolved basic piped water supply,\u201d Arief said.<\/p>\n
Currently, PAM Jaya\u2019s piped water service coverage has reached 80.24\nper cent with approximately 12,835 kilometres of pipelines, serving\n1,178,022 customers, and water distribution capacity reaching 22,583\nlitres per second.<\/p>\n
Arief targets achieving 100 per cent piped clean water coverage in\nJakarta by 2029, with a pipeline network of 16,234 kilometres and water\nsupply capacity of 31,563 litres per second.<\/p>\n
According to PAM Jaya data, approximately 92 per cent of Jakarta\u2019s\nraw water comes from outside the capital, particularly from Jatiluhur\nReservoir in Purwakarta. The remaining eight per cent comes from sources\nwithin Jakarta. For treated water, approximately 88 per cent originates\nfrom outside Jakarta and 12 per cent is produced within the DKI Jakarta\nregion.<\/p>\n
Meanwhile, Bappeda DKI Jakarta\u2019s head of development and\nenvironmental affairs Cipta Aditya stated that the provincial government\nis preparing policies to expand groundwater-free zones as part of\nefforts to reduce dependence on groundwater sources.<\/p>\n
According to Cipta, studies on expanding groundwater-free zones were\nactually conducted last year by the Water Resources Service. \u201cWe\u2019re now\nin the process of drafting the gubernatorial regulation. Hopefully it\ncan be accelerated soon,\u201d Cipta said.<\/p>\n
Currently, Jakarta has Governor Regulation Number 93 of 2021 on\nGroundwater-Free Zones, which serves as the basis for controlling\ngroundwater use in several Jakarta areas.<\/p>\n
However, Cipta emphasised that groundwater use restrictions cannot be\nimposed unilaterally without providing alternative water sources for the\npublic.<\/p>\n
\u201cThe government cannot ban groundwater use if alternatives aren\u2019t yet\navailable. So once piped water service is established, then we can\nencourage stopping groundwater use,\u201d he said.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/dki-requests-high-rise-building-owners-to-halt-groundwater-use-1773233611", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
