The blue water tanker rumbles into the slim lanes of Muara Angke, a fishing group on Jakarta’s northern coast, each few days.
Inside minutes, residents emerge carrying hoses and plastic containers. Some join pipes snaking by means of the densely packed group. Others wait with buckets.
For households right here, in one of many poorest neighborhoods on this planet’s most populous metropolis, the truck delivers one thing tens of millions of individuals in Indonesia’s capital nonetheless can’t depend on: clear water.
“When the deliveries cease, life rapidly turns into inconceivable,” mentioned Ellah, who runs a small neighborhood water kiosk.
“For seven days,” she recalled of 1 such occasion, “folks couldn’t wash. They couldn’t cook dinner.”
Jakarta’s public water utility, PAM JAYA, says it’s making an attempt to alter that.
Since returning town’s water system to full public management in 2023, the utility has launched into its most bold growth in a long time, aiming to offer piped water to each family by 2029.
It says protection has already elevated from simply over 60 %, when it took over, to about 82 % of residents this 12 months, with tens of hundreds of latest family connections put in over the previous 12 months as a part of a broader effort to scale back dependence on groundwater.
However it’s extra than simply about making certain entry to wash water.
Dwelling to greater than 12 million folks within the metropolis correct and 42 million within the wider metropolitan space, Jakarta can also be globally often known as the world’s fastest-sinking metropolis – one of many prime causes behind the controversial choice to construct a brand new capital, Nusantara, in East Kalimantan.
Scientists say extreme groundwater extraction in Jakarta, somewhat than rising sea ranges, is the first motive components of town are sinking by as much as 15 centimeters a 12 months, with some research recording even sooner charges. Some neighborhoods have already subsided by as a lot as 4 meters for the reason that Seventies.
Dependable piped water is extensively thought to be some of the necessary long-term options. The extra households related to the community, the less have to drill wells into the aquifers beneath town.
But for tens of millions of Jakartans, that transition stays incomplete.
In contrast to a lot of town, municipal pipes have by no means reached Ellah’s group of about 200 households residing in picket houses above the tidal waters of the north coast.
So in 2016, she constructed her personal miniature distribution system.
Each few days, she buys an 8,000-liter tanker of water, shops it in giant tanks outdoors her residence, and sells it to round 15 neighboring households by means of an internet of plastic hoses.
Even then, clear water comes at a value.
For a lot of households, shopping for sufficient water for cooking, washing, and bathing can price as much as 600,000 rupiah ($33) a month. Common month-to-month family salaries within the space are about 1.5 to three million rupiah ($80 to $160).
“We really feel like we’re simply ignored out right here on the perimeters [of the city],” Ellah mentioned.
Close by, 68-year-old former fisherman Husnin additionally buys water as a substitute of receiving it by means of family pipes.

His household spends round 40,000 rupiah ($2.20) each three days on water for laundry and cooking, whereas consuming water should be bought individually from refill stations.
These prices have change into more durable to soak up as fish shares decline and incomes shrink.
“[Access to water] is our proper as residents,” he mentioned. “And it’s the duty of the federal government to offer it.”
Close by in Penjaringan, 46-year-old grandmother Sadiya has no piped connection both.
As an alternative, a hose runs from a close-by mosque, the place groundwater is pumped into her residence for 150,000 rupiah every month.
When the pump fails, she should purchase water from distributors, spending as a lot as 30,000 rupiah a day ($1.70) – an enormous burden for a family that typically earns lower than 1 million rupiah ($56) every month.
“I really feel unhappy,” she mentioned. “Generally I’m late on the month-to-month cost as a result of the cash needs to be divided for all the pieces else.”
In the meantime, just some kilometers away in Rawabadan Selatan, households had been related to the municipal water community about two years in the past. That they had beforehand relied on bore water, which, resulting from seawater infiltration and air pollution, was usually too soiled to cook dinner, bathe, and even clear with.
“It’s so significantly better,” mentioned Walimah of the piped provide. “Beforehand [the borehole water] made us itchy. We needed to rinse once more with [cleaner] water.”
The historic dependence on groundwater in Jakarta has created a vicious cycle.
As groundwater is pumped from beneath town, the land sinks. Underground pipes crack and shift, permitting handled water to leak earlier than it reaches prospects.
In accordance with PAM JAYA, as a lot as 50 % of Jakarta’s handled water is misplaced by means of leakage, lowering income wanted to restore ageing infrastructure and prolong the community into underserved communities.
The result’s a cycle that has continued for many years: restricted piped water drives groundwater extraction, groundwater extraction accelerates land subsidence, and subsidence additional damages the very community wanted to interrupt that dependence.
For Universitas Tarumanagara lecturer Wahyu Kusuma Astuti, who not too long ago accomplished her PhD on Jakarta’s water infrastructure, the roots of the issues started greater than a century in the past.
Jakarta’s piped water community was initially constructed in the course of the Dutch colonial interval to serve European neighborhoods, leaving most native Indonesian communities with out entry from the outset.
“The pipe system was restricted within the previous colonial enclaves,” she mentioned. “The native communities weren’t related from the start.”
As Jakarta grew into one of many world’s largest cities, the community by no means stored tempo with its quickly increasing inhabitants. Huge areas as a substitute got here to rely upon groundwater.
By the Nineteen Nineties, metropolis leaders confronted mounting stress to increase water companies. Quite than funding the large funding themselves, the federal government turned to non-public operators.

In 1997, underneath President Suharto, Jakarta’s water system was divided between British utility Thames Water and France’s Suez underneath long-term concession agreements meant to quickly increase entry.
Contracts had been awarded by means of political and enterprise networks carefully linked to the Suharto household. Protection was anticipated to achieve nearly 98 % underneath these agreements.
As an alternative, critics argue, the concessions left Jakarta locked into a long time of underperformance.
A 2026 analysis paper by Ade Hendraputra, a planner in Indonesia’s Ministry of Planning and Growth, argues that the preparations created a “governance void,” with no single establishment possessing both the authority or the inducement to handle town’s water system as an built-in complete.
In the meantime, many wealthier households, companies, and authorities workplaces deserted the community altogether, drilling their very own groundwater wells as a substitute.
The results bolstered each other.
For infrastructure and concrete water governance researcher Marwa, who’s finishing her PhD on Jakarta’s water governance on the College of Cambridge, the underlying drawback is that water has lengthy been handled as an funding alternative somewhat than a public service.
“Water infrastructure has by no means been prioritized, and the duty to finance, traditionally talking, has all the time been outsourced to exterior actors,” she mentioned.
The results are most seen in Jakarta’s poorer neighborhoods, the place households with out connections usually pay the best costs for water from water tankers and road distributors.
Some households, she mentioned, spend nearly one-third of their earnings shopping for water, whereas intermittent provide means residents may be compelled to remain awake late into the night time filling buckets at any time when water begins flowing.
“The burden of gathering the water additionally falls totally on the ladies,” she mentioned.
Following a long time of complaints about poor service, excessive tariffs, and under-serviced low-income areas, a profitable citizen lawsuit led to water companies returning to public administration in 2023.
Nevertheless, Marwa argues that most of the monetary incentives stay largely unchanged.
“It’s extra about mobilizing finance,” she mentioned, describing what she sees as a technique of “derisking personal sector privatization.”
She believes this continues to favor investments with extra predictable returns whereas making it more durable to prioritize common family connections.
Fellow researcher Wahyu says that whereas public firm PAM JAYA now operates the system, the utility stays tied to most of the industrial preparations established underneath the earlier mannequin.
Non-public corporations, she says, proceed to favor lower-risk investments comparable to water remedy crops, whereas the general public utility bears the large price of changing ageing pipelines and buying handled bulk water, regardless of nearly half of that water leaking earlier than reaching prospects.
“They need to pay again for the majority water provide,” she says, despite the fact that “half of the water that they channel really leaks.”
“We recognized the issue a very long time in the past, however we’re pursuing options that don’t work.”
Environmental group WALHI argues that increasing pipelines alone is not going to clear up Jakarta’s water disaster.

Muhammad Aminullah, govt director of WALHI Jakarta, mentioned that rising family connections should be matched by dependable service and higher water high quality if residents are to desert groundwater.
Though a lot of Jakarta is now coated by the piped community, he mentioned many households proceed counting on different sources as a result of they don’t belief the water provide.
“Though a big portion of the group is roofed by the [public infrastructure], the water isn’t all the time getting used,” he mentioned. “WALHI suspects this is because of poor water high quality and inconsistent continuity.”
He additionally argues that the controversy has targeted too closely on family groundwater use whereas overlooking the a lot bigger volumes extracted by industrial customers.
“Rules should be tightened for the industrial and personal sectors, comparable to motels and industries,” he mentioned. “These sectors use deep wells, which have a way more vital impression than the shallow wells utilized by households for home functions.”
For Aminullah, the difficulty finally extends past infrastructure.
“Water is a human proper that ought to be fulfilled by the state, not by profit-oriented personal entities,” he mentioned, arguing that Jakarta’s water system continues to prioritize market mechanisms over common entry.
PAM JAYA declined to remark for this text. In a press launch this month, it mentioned that increasing entry to secure piped water was its essential purpose, and that it had accelerated its funding since water companies had been returned to full public management.
It mentioned greater than 72,000 new family connections had been put in throughout 2025, lifting protection to about 82 % of Jakarta’s inhabitants, whereas new remedy crops and distribution infrastructure are meant to scale back dependence on groundwater forward of its purpose of common piped water entry by 2029.
Whether or not these ambitions can lastly break Jakarta’s dependence on groundwater – and assist gradual the subsidence threatening the world’s most-populous metropolitan space – stays one of many defining challenges going through Indonesia’s capital.
