Jakarta is a bustling metropolis of greater than 10 million recognized for its vibrant tradition. But it surely’s grappling with a extreme water disaster.
Indonesia’s meteorological division has warned the nation may face a chronic drought this 12 months. It’s been projected that Indonesia may plunge right into a clear water disaster by 2040.
The mixture of maximum climate, air pollution and underinvestment in water infrastructure is already pushing cities like Jakarta to the brink.
Jakarta’s water system faces myriad challenges that make it unsafe to devour instantly from the faucet, together with extreme ranges of salt doubtless resulting from seawater intrusion into groundwater wells together with excessive ranges of manganese and iron compounds.
Indonesia’s capital depends on varied water sources which might be steadily polluted by industrial and home waste.
With solely 15 % of households gaining access to ample ingesting water as of 2020, the town’s residents are already grappling with a deteriorating water provide system, elevating issues about the way forward for clear water in considered one of Southeast Asia’s largest city centres.
However maybe the options to Jakarta’s water woes may very well be discovered by trying to Europe.
Unsafe to drink
Traditionally, rivers supplied a straightforward ingesting water resolution, however in Jakarta rampant air pollution from industrial and home waste has made them unusable.
Town’s underdeveloped and outdated water system leaves a lot of the inhabitants depending on bottled water or polluted groundwater sources.
DKI Jakarta Regional Regulation appointed PT PAM Jaya to supply piped clear water for Jakarta residents. Water high quality is regulated by the Ministry of Well being.

Jakarta’s ageing infrastructure and lack of funding imply that even handled water typically falls in need of security requirements by the point it reaches the faucets in folks’s houses.
In 1997, operation of the piped water distribution was then transferred from PAM Jaya to the 2 non-public corporations for 25 years – PT PAM Lyonnaise Jaya (PALYJA) and PT Thames PAM Jaya. On the finish of 2023, PT PAM Jaya resumed full management of the water provide system.
Whereas water from the river is handled and adheres to laws, it can’t be consumed from the faucet because it doesn’t meet the Indonesian Nationwide Normal for ingesting water.
Nonetheless, even this transfer has been broadly criticised for its inefficiency, as solely 67 per cent of households can presently obtain piped water. The remainder should depend on contaminated water sources.
In the course of the dry season in 2023, 18 districts in Jakarta confronted water shortages, sparking a civil lawsuit in opposition to privatisation.
Classes from Europe
In contrast to European cities corresponding to Vienna and Berlin, the place stringent laws and superior infrastructure guarantee secure ingesting water, Jakarta struggles to fulfill the specified necessities for potable water.
The European Union’s Consuming Water Directive, for instance, regulates the high quality of faucet water with rigorous requirements and frequent testing together with improved monitoring for rising pollution like microplastics and endocrine-disrupting chemical substances.
In distinction, Jakarta’s ageing infrastructure and lack of funding imply that even handled water typically falls in need of security requirements by the point it reaches the faucets in folks’s houses.
Efforts to enhance Jakarta’s water system are underway, however with an 89 per cent reliance on bottled water for secure ingesting, there’s nonetheless an extended method to go.
From river water to recycling water
Implementing large-scale water reuse and recycling may alleviate a few of the strain on Jakarta’s water provides, however it’s going to require a cultural shift and vital funding in infrastructure.
In Europe, the administration of rainwater and wastewater can also be essential to sustaining the excessive requirements of ingesting water high quality and making certain environmental sustainability.
Rainwater harvesting programs in Europe can save between 20 and 100 per cent of non-potable water, considerably decreasing vitality calls for and lowering faucet water use by one-third for family functions corresponding to bathroom flushing.
Regardless of the Indonesian authorities’s new laws on water reuse, scepticism and cultural limitations such because the stigma round human waste within the river stay main obstacles to the adoption of sustainable water practices in Jakarta.
Public reluctance, regardless of a 2010 fatwa from the Indonesian Council of Ulama affirming the halal standing of recycled water, means the town will not be maximising its water assets. For instance, if we are able to use the recycled greywater within the Istiqlal Mosque, it may well save clear water as much as 35 per cent.
Indonesia’s water disaster, significantly in Jakarta, underscores the pressing want for modernisation and long-term planning.
Risks of local weather change
With out vital funding in water infrastructure, tens of millions will proceed to devour unsafe ingesting water, and the nation dangers falling additional behind as local weather change accelerates water shortage.
Economically, water shortage, worsened by local weather change may cut back GDP by as much as 6 per cent in some areas, drive migration, and set off conflicts.
When governments deal with water shortages by enhancing effectivity and reallocating simply 25 per cent of water to higher-value makes use of, corresponding to extra environment friendly agricultural practices, water losses can lower considerably, and in some areas, could also be eradicated altogether.
The problem lies not solely in upgrading water programs but in addition in addressing societal resistance to water reuse, as urbanisation will increase the demand for water.
As extra folks transfer to city areas — anticipated to embody 68 per cent of the worldwide inhabitants by 2050 — making certain equitable entry to scrub water turns into essential.
Water use and reuse is without doubt one of the highlighted points on the upcoming COP29 convention and challenges corresponding to equitable entry, sustainable administration of assets and the mixing of progressive water applied sciences into present infrastructure stay urgent issues for a lot of nations.
