The Citarum River in Indonesia has been dubbed the world's most polluted river by the World Bank. Decades of neglect and industrial mismanagement have turned the once pristine river into a toxic swamp. The river is heavily polluted by human activity, with about 2,000 factories dumping over 20,000 tons of waste and 340,000 tons of wastewater into the river daily. The pollution has had severe environmental and health impacts, including the elimination of 60% of the river's fish population, reduced rice yields, and skin and respiratory problems for people living along the river. In 2018, the Indonesian government launched a seven-year river revitalisation program, but it remains to be seen if these efforts will be successful in restoring the Citarum to a healthy state.

The Citarum River is the longest and largest river in West Java, Indonesia
The Citarum River, also known as the Tarum River, is the longest and largest river in West Java, Indonesia. It is the third-longest river in Java, stretching for 300 kilometres or 270 kilometres according to different sources. The river plays a crucial role in the lives of the people of West Java, providing water for drinking, cooking, washing, and irrigating rice fields, as well as supporting the region's electricity supply.
However, the Citarum River has also been dubbed the "world's dirtiest river" by the World Bank and is considered one of the most polluted rivers globally. Decades of neglect and mismanagement have turned the once-pristine waterway into a toxic swamp. More than 2,000 factories, mostly from the textile industry, rely on the river for their water supply and dispose of their wastewater into it. This has led to severe pollution from lead, aluminium, manganese, iron, mercury, arsenic, and other toxins. The pollution has had devastating consequences on the environment and the health of the people living along the river, with skin diseases, respiratory problems, and other illnesses being commonly reported.
The Indonesian government has recognised the severity of the problem and has implemented various measures to clean up the river. In 2018, the government established the Citarum Harum, a seven-year river revitalisation programme with the goal of making the river's water drinkable by 2025. The programme includes reforesting surrounding mountains, extracting toxic sediment, regulating wastewater discharge, and environmental education projects. Soldiers have been deployed to clean allocated sections of the river and install rubbish and water treatment facilities.
Despite these efforts, challenges remain. The polluters provide many jobs in the region, and there is a lack of coordination and enforcement of regulations at the local level. Bribery and false reporting by factories have also hindered progress. Environmental activists have played a crucial role in advocating for the river's cleanup and taking legal action against polluting industries.
The Citarum River's pollution problem is complex and deeply entrenched. With the weight of various stakeholders and the health of millions of people at stake, finding a sustainable solution is of utmost importance.

It is relied upon by millions for food, water, and electricity
The Citarum River in Indonesia is relied upon by millions for food, water, and electricity. It is the longest and largest river in West Java, stretching for 300 kilometres and providing a crucial water supply for local livelihoods. The river plays an important role in the life of the people of West Java, with around 25 million people living in its basin and thousands of waste-producing factories located along its course.
The Citarum River is a source of irrigation for vast rice paddies in the Karawang and Bekasi areas, making northern West Java lowlands one of the most productive rice farming areas. However, pollution from factories and households has contaminated the water, leading to a decline in rice yields and health issues among the local population. High levels of toxins and heavy metals have been found in the water, including lead, mercury, arsenic, and other toxins. The water from the river and its tributaries is used to irrigate crops, leading to the ingestion of contaminants through food.
The river is also a source of electricity, with three hydroelectric power plant dams installed along its course: Saguling, Cirata, and Ir. H. Djuanda (Jatiluhur). These dams supply electricity to the Bandung and Greater Jakarta areas. However, the pollution in the river has affected the functioning of these dams and the overall ecosystem.
The Indonesian government has recognised the severity of the problem and has implemented river revitalisation programs, such as the Citarum Harum, with the goal of making the river's water drinkable again. The program includes reforesting surrounding mountains, extracting toxic sediment, regulating wastewater discharge, and environmental education projects. Local universities and environmental agencies are also working to address the sources of contamination and find solutions.
The Citarum River is relied upon by millions, and its pollution has had a significant impact on the lives and livelihoods of the people in the region. The river's revitalisation is a complex and challenging task, but it is crucial to ensure the health, well-being, and sustainability of the communities that depend on it.

Decades of pollution have choked it with chemicals and rubbish
The Citarum River, located in West Java, Indonesia, is considered one of the most polluted rivers in the world. Decades of pollution have choked it with chemicals and rubbish, posing significant risks to the health and well-being of the surrounding communities and the environment.
The river, which stretches for approximately 300 kilometres, serves as a crucial water source for the region. However, it has been severely contaminated by industrial and household waste. Along the riverbed are approximately 2,000 industrial facilities, with the textile industry being a major contributor to toxic waste. These factories discharge an estimated 20,000 tons of waste and 340,000 tons of wastewater into the river daily, according to environmentalists. The wastewater contains a range of toxins, including lead, mercury, arsenic, sulphites, nonylphenol, and Phthalates.
The high levels of pollution in the Citarum River have resulted in severe environmental and health consequences. The river's fish population has decreased by 60% since 2008, and the water quality is deemed unsafe for human use. People living along the river suffer from various skin diseases, respiratory issues, and other health problems due to exposure to contaminated water and inhalation of factory smoke. The pollution has also impacted agriculture, with rice yields dropping significantly as farmers irrigate their fields with polluted water.
In response to the dire situation, the Indonesian government, supported by international organisations, has implemented river revitalisation programmes aimed at restoring the Citarum River. The government's seven-year cleaning programme, established in 2018, involves reforesting surrounding mountains, extracting toxic sediment, regulating wastewater discharge, and conducting environmental education projects. Soldiers have been tasked with cleaning sections of the river and installing rubbish and water treatment facilities. Additionally, local universities and environmental agencies are working to address the sources of contamination and find sustainable solutions.
The river's pollution has also led to economic consequences. With the river choked by waste and industrial wastewater, the World Bank estimates that a successful clean-up could bring significant economic benefits to Indonesia. A revitalised Citarum River ecosystem would improve water quality, increase crop yields, and revitalise the volume of fish in the river, making riverside properties more aesthetically pleasing and attractive for development.

Over 20,000 tons of waste and 340,000 tons of wastewater are disposed of into the river daily
The Citarum River, also known as the Tarum River, is the longest and largest river in West Java, Indonesia. It is the third-longest river in Java and is considered one of the most polluted rivers in the world. The river plays a significant role in the lives of the people of West Java, providing water for various purposes, including irrigation, drinking, and energy generation.
However, the Citarum River has been facing a major issue with pollution, and over 20,000 tons of waste and 340,000 tons of wastewater are disposed of into the river daily. This pollution primarily comes from the approximately 2,000 textile factories located near the river, with other industries also contributing. These factories discharge enormous amounts of chemical waste, including lead, mercury, arsenic, and other toxins, directly into the river. The wastewater from these factories contains high levels of toxic chemicals, such as sulphites, nonylphenol, phthalates, and heavy metals.
The impact of this pollution has been devastating for the river's ecosystem and the people who depend on it. The river, once known for its clear and pristine waterways, is now covered with garbage, trash, and dead animals in many places, making the water invisible beneath the waste. The pollution has also led to a significant decline in the river's fish population, with a decrease of up to 60% since 2008.
The high levels of pollution in the river have severe consequences for the health of those who rely on it. The water has been found to contain lead levels that are 1,000 times higher than US drinking water standards, and other heavy metals such as aluminium, iron, and manganese are also present at dangerous levels. As a result, people who use the river's water for drinking, cooking, and washing have developed various skin diseases, infections, and respiratory issues.
Recognising the severity of the problem, the Indonesian government, with support from organisations like the International Monetary Fund and the Asian Development Bank, has established river revitalisation and cleaning programmes. These programmes aim to remove toxic sediment from the river, improve wastewater treatment, and promote environmental education to achieve clean drinking-water status for the Citarum River by 2025.

In 2018, the Indonesian government established a seven-year river revitalisation program
The Citarum River, the longest and largest river in West Java, Indonesia, has been noted as one of the most polluted rivers globally. Decades of pollution have contaminated the river with chemicals and rubbish, severely impacting the health and livelihoods of the millions who rely on it.
In recognition of the dire situation, the Indonesian government established the Citarum Harum in 2018, a seven-year river revitalisation program with the ambitious goal of making the Citarum's water drinkable by 2025. This target is no small feat, but the program has garnered significant support from various organisations. The International Monetary Fund and the Asian Development Bank have committed financially, while local universities, environmental agencies, and the global research community are collaborating to address contamination sources and find solutions.
The Citarum Harum program encompasses several key strategies. One strategy is reforesting the surrounding mountains to combat soil erosion and agricultural runoff, a significant contributor to river pollution. Another crucial aspect is extracting the toxic sediment that has built up in the river over the years due to industrial wastewater discharge. This involves prohibiting factories from releasing wastewater into the river until it has undergone proper filtration and purification processes.
Additionally, the program focuses on regulating wastewater discharge and setting up environmental education projects to raise awareness and promote responsible practices among the community. To achieve these goals, soldiers have been deployed to clean allocated sections of the river and install rubbish and water treatment facilities. The program also addresses the challenges posed by upstream soil erosion from deforestation, which exacerbates silting in the lower river.
The success of the Citarum Harum program is crucial not only for improving water quality and ecosystem health but also for realising economic benefits. A World Bank estimate predicts that a clean Citarum River could bring Indonesia annual economic benefits of up to $280 million. This includes improved drinking water quality, enhanced crop yields, and a revitalised ecosystem with an increased volume of fish.
