The Citarum River, also known as the Tarum River, is the longest and largest river in West Java, Indonesia. It is relied upon by millions of people for drinking, cooking, fishing, and irrigation. However, decades of pollution have turned it into a toxic swamp, with rubbish, chemicals, toxins, and wastewater from the 2,000 factories along its riverbed being dumped into the river. In addition, poor waste management in the surrounding communities has led to household waste, sewage, and agricultural runoff ending up in the river. As a result, the Citarum River has been dubbed the world's dirtiest river by the World Bank, and the Indonesian government has launched a seven-year cleaning program to make its water drinkable again by 2025.

The Citarum River is the world's most polluted river
The Citarum River in Indonesia has been dubbed the world's most polluted river. Stretching for 300 kilometres, it is the longest and largest river in West Java and the third-longest river in all of Java. It is relied upon by millions of people for drinking water, fishing, and agriculture, but decades of pollution have choked it with chemicals and rubbish.
The primary source of pollution is the 1,900 to 2,000 industries located along the river, most of which are from the textile industry. These factories dump around 280 tonnes of toxins into the river daily, including lead, mercury, arsenic, cadmium, cobalt, and manganese. In addition to industrial waste, household waste is also a major contributor to the pollution. Residents along the river basins often lack the funds to install proper sewage systems or water treatment facilities, so they dispose of their waste by burning it or throwing it into the river.
The pollution has had severe consequences for the environment and human health. A significant part of the river's fish population has been eliminated, with a decrease of 60% since 2008. The water is contaminated with heavy metals and microplastics, and those who eat the fish are ingesting these contaminants. Rice fields irrigated with water from the river can no longer produce sufficient amounts of rice, and the river contains so little oxygen that it is essentially a "death river".
The Indonesian government has recognised the severity of the problem and has launched several initiatives to clean up the Citarum River. In 2018, President Joko Widodo initiated a seven-year plan to make the river's water drinkable by 2025. The programme is supported by the International Monetary Fund and the Asian Development Bank, which committed $500 million to fund the river's rehabilitation. The military has also been involved in the clean-up efforts, with soldiers clearing garbage and installing rubbish and water treatment facilities.

2,000 factories dump 20,000 tons of waste and 340,000 tons of wastewater into the river daily
The Citarum River in Indonesia is considered one of the most polluted rivers in the world. The river is relied upon by millions of people for agriculture, water, and electricity. However, it is contaminated with chemical waste, rubbish, and toxins, making the water unsafe for human use.
Every day, 2,000 factories, mostly textile factories, dump 20,000 tons of waste and 340,000 tons of wastewater directly into the river. This has resulted in severe pollution from lead, aluminum, manganese, iron, mercury, arsenic, and other toxins. The levels of lead in the river have been found to be 1,000 times higher than US drinking water standards, and the levels of other heavy metals are also above the international average.
The pollution has had a significant impact on the river's ecosystem and the people who depend on it. The fish population in the river has decreased by an estimated 60% since 2008, affecting the livelihood of fishermen like Suratmo, who now makes a living collecting garbage from the river. Those living along the river suffer from various skin diseases, respiratory distress from inhaling factory smoke, and other health issues due to the polluted water.
The Indonesian government, with support from international organizations, has recognized the severity of the problem and has implemented a seven-year cleaning program for the Citarum River, aiming to make its water drinkable by 2025. The program includes reforestation, extraction of toxic sediment, prohibition of wastewater discharge without filtration, and environmental education projects. It is estimated that reforestation will require the planting of 125 million trees in the vicinity of the river.
The success of the cleaning program is crucial not only for improving the health and well-being of the people living along the river but also for the potential economic benefits. The World Bank has estimated that a clean Citarum River could bring economic gains of up to $280 million annually, through improved water quality, increased crop yields, and the revitalization of the ecosystem and fish population.

The river is a crucial water supply for 25 million people
The Citarum River is the longest river in West Java, Indonesia. It is relied upon by millions, including 25 million people who depend on it for drinking water. It is also used to irrigate 400,000 hectares of rice fields, which is then consumed by families whose diets consist largely of locally grown rice.
The river provides 80% of the water supply for Indonesia's capital, Jakarta, and is the source of energy for three hydroelectric power stations serving three cities. However, the river has been dubbed the "world's dirtiest river" by the World Bank. It is heavily polluted by human activity, with about 5 million people living in its basin.
The primary source of pollution is the 1,900 to 2,000 industries located along the river, most of which are from the textile industry. These facilities dump 280 tons of toxins into the river daily, including lead, mercury, arsenic, cadmium, cobalt, and other toxins. The wastewater from these factories also contains high concentrations of toxic heavy metals, such as lead, mercury, iron, and manganese.
The pollution in the Citarum River has had severe health consequences for the people living along its banks. Many suffer from various skin diseases, respiratory distress due to inhaling factory smoke, and increased rates of tuberculosis and bronchitis. The water from the river is often yellow to black in color, and fishing is still practised along the river, with the contaminated catch being sold and eaten in areas adjacent to the river and in Jakarta.
In response to the river's degradation, the Indonesian government, with support from the International Monetary Fund and the Asian Development Bank, launched a seven-year cleaning program in 2018, with the goal of making the Citarum's water drinkable by 2025. The program involves reforestation, toxin extraction, wastewater discharge regulation, and environmental education. It is hoped that these efforts will drastically improve the health and livelihoods of the millions of people who depend on the Citarum River.

The Indonesian government has a seven-year plan to clean up the river
The Citarum River in Indonesia is considered one of the world's most polluted rivers. It is relied upon by millions of people, but decades of pollution have contaminated it with chemicals and rubbish. The Indonesian government has acknowledged the severity of the issue and, in 2018, President Joko Widodo launched a seven-year plan, called Citarum Harum, to clean up the river and make its water drinkable by 2025.
The Citarum River, the longest river in West Java, plays a crucial role in the lives of the people in the region. It provides water for agriculture, industry, and daily use, supporting the livelihoods of those who depend on it. However, the river has been severely polluted by human activity, with about five million people living in its basin. The pollution is mainly caused by the discharge of wastewater and toxic chemicals from the approximately 2,000 factories, mostly textile manufacturers, located along its banks. This has led to the river becoming contaminated with toxins such as lead, mercury, arsenic, and other heavy metals, resulting in the decline of fish species and the contamination of agricultural produce.
Recognizing the urgency of the situation, the Indonesian government has taken decisive action. President Joko Widodo's seven-year plan involves deploying soldiers and joint personnel led by the Indonesian Army to clean allocated sections of the river regularly. The plan also includes reforesting the surrounding mountains, extracting toxic sediment, regulating wastewater discharge, and implementing environmental education projects. Local universities, environmental agencies, and international organizations like Greenpeace are also contributing to the effort by addressing contamination sources and proposing solutions.
The government's plan has received significant backing from organizations like the International Monetary Fund and the Asian Development Bank, which committed $500 million to support the river's rehabilitation. However, the cleanup effort faces challenges, including the need to address the vast number of businesses along the riverbank and the tens of millions of households depending on its water. Political and administrative hurdles, as well as the need for greater coordination and enforcement, also pose difficulties in ensuring the plan's success.
The seven-year timeline set by the Indonesian government demonstrates its commitment to tackling the pollution in the Citarum River. By combining short-term actions, such as deploying soldiers for cleanup, with long-term strategies like environmental education and reforestation, the government aims to achieve the goal of making the river's water drinkable by 2025.

Reforestation will require 125 million trees
The Citarum River 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, severely affecting the agriculture and fishing industries. In 2013, the Blacksmith Institute in New York and the Green Cross in Switzerland ranked the Citarum as the world's most polluted river, as a study showed that 2,000 textile factories dump 280 tons of toxic chemicals into the river daily. This has resulted in a significant decline in fish species, with nearly 60% of fish species destroyed since 2008. The river is also a source of water for the Jatiluhur Reservoir, which provides 80% of the water supply for the capital city. However, the river's water quality does not meet the standards set by the government, with dangerously high levels of lead, aluminium, manganese, and iron.
Recognizing the severity of the problem, the Indonesian government, with support from the International Monetary Fund and the Asian Development Bank, launched a seven-year cleaning program in 2018, aiming to make the river's water drinkable by 2025. This program includes various initiatives, such as combating soil erosion and agricultural runoff, extracting toxic sediment, and setting up environmental education projects.
A crucial aspect of the river's rehabilitation is reforestation. It is estimated that reforestation will require 125 million trees, including 25 million hardwood plants and 100 million shrubs, to be planted in the immediate vicinity of the river. This massive undertaking aims to address the issue of flooding caused by clogged garbage and overflowing rivers. Reforestation will also help combat soil erosion, which is a contributing factor to the silting of the lower river.
Organizations like Trees4Trees, in collaboration with the Indonesian government and Microsoft, are actively working towards this goal. Trees4Trees typically spends a minimum of five years in an area, not only planting trees but also educating the community about the benefits of rehabilitation. Their efforts in the Citarum River watershed aim to plant a minimum of 10 million trees by 2025, with the participation of local communities and farmers.
The success of the reforestation efforts is critical to the overall goal of restoring the Citarum River to a healthy state. By addressing the root causes of pollution and working together with various stakeholders, there is hope that the river can be revitalized, bringing not only environmental benefits but also economic gains for the surrounding communities.
