A data centre that would drink as much water as 220,000 people was halted in a week: Indonesia's AI boom meets local resistance

Can Indonesia's AI boom survive its water problem? A halted project in West Java suggests the answer depends on where data centres are built. Construction of a major data centre in Jatiluhur was stopped on 30 September, just a week after its groundbreaking, after the local community pushed for a review of its water use, projected to equal the daily needs of 220,000 people, according to an analysis in The Jakarta Post.

The case is not isolated. In Batam, one of Indonesia's largest data centre clusters, protests over the strain on a limited rain fed water supply have pushed authorities to require data centres to build their own seawater desalination plants. With more than 60 percent of the country's data centres concentrated in Greater Jakarta and Batam, the clash between AI infrastructure and local resources is becoming one of Southeast Asia's defining development debates.

Why Jatiluhur was halted

Jatiluhur in West Java is home to one of Indonesia's largest reservoirs, which supplies water for drinking, farming and industry across the region. When residents learned that a planned data centre could consume as much water every day as 220,000 people, they pushed for a review. Construction stopped a week after the groundbreaking ceremony.

The speed of the halt is striking. It shows that local communities in Indonesia are prepared to challenge large AI projects, and that authorities are willing to pause them when resource concerns are raised. For investors, it adds a new category of risk to data centre development: the social licence to operate.

Water has long been a sensitive issue in West Java, where rapid urban growth around Jakarta and expanding industry already compete for supply. A single facility using as much water as a mid sized town would add to that pressure, which explains why residents moved quickly once the projected figures became known.

Batam's water crunch

Batam, an island near Singapore, has become a major data centre hub because of its proximity to Singapore's network infrastructure and its role in the Singapore, Johor and Batam corridor. But its water supply depends largely on rainfall, and the continued expansion of data centres has put pressure on that supply.

Local protests followed, prompting authorities to require data centres to develop independent seawater desalination facilities. Desalination solves the water conflict but adds cost and energy demand, which in turn raises questions about electricity supply and emissions.

The AI race is often described as a contest of chips and algorithms. On the ground in Southeast Asia, it is a contest for water, power and the patience of the people who live nearby.

Data centres need large amounts of electricity to power servers, cooling systems to remove heat, reliable network connectivity and land. As AI computing demand pushes facilities to grow larger, those needs increasingly compete with households and other industries.

Batam's position makes it difficult to replace. Its proximity to Singapore gives data centres there low latency connections to one of Asia's most important internet hubs, and land and power have historically been cheaper than in Singapore itself. That is why developers have been willing to accept new requirements such as desalination rather than move elsewhere.

A regional and global backlash

Indonesia is part of a wider trend. In the United States, at least 120 data centre projects worth about 198 billion dollars were delayed or blocked by local opposition in the first half of 2026, many citing electricity, water and noise concerns, according to the analysis.

Malaysia, Southeast Asia's data centre leader, faces similar pressures. The first data centre related protest in Malaysia took place near ZDATA's 300 megawatt facility in Johor. Selangor has mandated a 30 percent local content requirement for new data centre investments, while Johor has stopped approving water intensive data centres that can consume up to 50 million litres of water per day. We covered Johor's power challenge in our report on Johor's data centres and the grid.

Concerns also extend beyond water. Data centres can involve large capital investments while creating relatively few permanent jobs after construction, which raises questions about how much value stays in the local economy. If new electricity demand is met with fossil fuel power, it can also make it harder for countries to meet their climate commitments.

How much capacity Indonesia is building

As of the first half of 2026, Indonesia had about 356 megawatts of operational data centre capacity, about 395 megawatts under construction and around 1.3 gigawatts planned. That pipeline is several times the current base, meaning the resource questions raised in Jatiluhur and Batam will only grow.

Investment is pouring into the region. Private funding for Southeast Asian data centres reached 16.3 billion dollars in the first half of 2026, as we covered in our report on Southeast Asia's AI paradox. The analysis, drawing on work by the Indonesian Business Council Institute, proposed a more deliberate approach to where capacity goes. Its key recommendations include:

• Assessing local water, power and grid capacity before approving projects
• Keeping latency sensitive cloud and AI inference near users in Greater Jakarta
• Maintaining Batam's role as a regional cloud gateway
• Directing power hungry AI training to areas with surplus renewable energy
• Rewarding projects that add new power, grid and non water cooling capacity

Different kinds of data centres have different needs, the analysis noted. Facilities used for AI training require huge amounts of power and cooling but can be located further from users, while those serving cloud services and AI inference need to be close to customers and reliable networks to keep delays low. Matching each type to the right location could ease the pressure on crowded hubs.

What it means for investors and communities

For data centre developers, Indonesia's experience means that site selection now involves community relations, water planning and energy sourcing as much as land and fibre. Projects that bring their own water and renewable power, or locate near geothermal and solar resources, may face fewer obstacles.

For communities, the debate is about who benefits. Data centres involve large capital investments but relatively few permanent jobs after construction, raising questions about the value retained locally. Governments across Southeast Asia, including Malaysia with its ambitious data centre plans, as shown in our report on Anwar's 50 billion dollar AI investment, will need to balance attracting investment with protecting local resources.

Transparency could help reduce conflict. Publishing expected water and power use before projects are approved, and showing how developers plan to source both, would give communities a chance to raise concerns early, rather than after construction has started, as happened in Jatiluhur.

Indonesia's halted Jatiluhur project and Batam's desalination rule show that the AI boom has physical limits measured in litres and megawatts. With a pipeline several times its current capacity, Indonesia must decide where data centres can grow without draining local resources. The countries that get that balance right will win the next wave of AI investment, and keep their communities on side.
