Sulphur in Brunei's river basins

Brunei, officially Brunei Darussalam, is a small country in Southeast Asia with a population of around 455,858 as of 2023. It is located on the northern coast of the island of Borneo and is surrounded by the Malaysian state of Sarawak, apart from its coastline on the South China Sea. The country has a tropical climate with high temperatures and rainfall.

Brunei has four main river basins: Temburong, Belait, Tutong, and Brunei. These river basins provide surface water, which makes up about 99% of the water used for all purposes in the country. The upper reaches of the Brunei River, in particular, are a major source of freshwater for the western part of Brunei. Despite being used for various activities such as transportation and waste disposal, the river has remained relatively unaffected due to its natural self-purification capacity.

However, high levels of water pollution in the Brunei River have been traced to wastewater treatment plants, industrial discharge, and polluted streams. Population density and urban catchment systems have been identified as the primary reasons for the pollution in the rivers, especially the Brunei River.

One of the bottled water brands in Brunei, Alam Water, is sourced from the pristine rainforest of the Tutong district. It is a natural mineral water with a high pH value of 8, which gives it a pleasant and refreshing taste. Alam Water contains several minerals, including sulphur, calcium, magnesium, sodium, potassium, zinc, and bicarbonate. These minerals are believed to offer health benefits and help achieve an ideal balanced system in the human body.

Another popular bottled water brand in Brunei is RainFresh Super Oxygenated Water, which is sourced from the purest spring water in the country's rainforests.

While there is no specific information available regarding the presence of sulphur in all of Brunei's river basins, the existence of sulphur in Alam Water, sourced from the Tutong district, indicates that sulphur may be present in at least one of the river basins. Additionally, the presence of industrial discharge and wastewater treatment plants contributing to the pollution in the rivers suggests that there could be sulphur compounds in the water.

Water treatment plants in Brunei

The surface water supply in Brunei, which accounts for about 99% of the water used for all purposes, originates from the four river basins: Daerah Tutong, Kuala Belait, and Temburong. The Brunei River has been a significant freshwater source for the western region of the country. However, high levels of water pollution in this river have been attributed to wastewater treatment plants, industrial discharge, and polluted streams. To address this issue, the government has identified population density and urban catchment systems as the primary factors contributing to the pollution levels.

To maintain water quality and meet the demands of a growing population, the government has proposed upgrades to existing monitoring systems and quality management frameworks under the Tenth National Development Plan. They have also introduced water conservation and sustainability measures, constructed new water infrastructure, and enhanced water quality monitoring through the establishment of a new water lab and the addition of 11 new water quality parameters.

One notable example of a water treatment plant in Brunei is the Mengkubau Water Treatment Plant. In 2021, this plant underwent replacement works for the MCCB switch of its raw water pump, which resulted in temporary water disruptions in several areas within the Brunei-Muara District. Such maintenance activities highlight the ongoing efforts to ensure the reliable functioning of water treatment facilities in the country.

Furthermore, Brunei is home to Alam Water, a natural mineral water brand sourced from the pristine rainforest of the Tutong district. Alam Water boasts a high pH value of 8, making it alkaline and particularly healthy for consumption. The water travels under high pressure through porous rocks, naturally filtering and purifying it while infusing it with essential minerals. Alam Water's quality meets the stringent standards set by the World Health Organization (WHO), ensuring that it is safe and beneficial for human consumption.

Brunei's water quality

Brunei is a highly industrialised sovereign state in Southeast Asia, with a tropical climate characterised by high temperatures and rainfall. The country's water quality is facing the threat of deterioration due to increasing population and economic development.

Current Water Quality in Brunei

The Brunei River has been a significant freshwater source for the western part of the country. Despite being used for transportation and waste disposal, it has remained relatively unaffected due to its natural self-purification abilities. However, high levels of water pollution in the river have been linked to wastewater treatment plants, industrial discharge, and polluted streams.

The majority of Brunei's drinking water comes from rivers, and the quality of this water supply is crucial for the country's population. Six government-operated water treatment plants help maintain good drinking water quality. Additionally, private companies like Brunei Shell Petroleum (BSP) and Brunei Shell's Liquefied Natural Gas (LNG) also run their own water treatment plants.

Potential Threats to Water Quality

The main sources of pollution in the Brunei River are point and non-point sources, including residential, industrial, and agricultural outlets. Domestic waste and surface runoff constitute about 50% and 29%, respectively, of the load discharged into the rivers. As the population grows and the country undergoes further economic development, these pollution levels are likely to increase, negatively impacting water quality.

Measures to Address Water Quality Issues

The government of Brunei has recognised the importance of maintaining high water quality standards and is taking steps to address the issue. They have proposed upgrades to monitoring systems and quality management frameworks under the Tenth National Development Plan. Additionally, they have introduced legislation to improve watershed protection and pollution management.

To maintain the supply and distribution of clean water, water conservation and sustainability measures have been suggested, along with new designs for riverside development and integrated water resource management plans. This includes the construction of new water infrastructure, such as drainage systems and treatment plants.

The Role of Climate Change

A study investigating the influence of climate change on water quality in Brunei found a correlation between changes in climate and water quality. Decreasing precipitation and increasing rainfall intensity were linked to rising aluminium concentrations in the water. Additionally, low pH values before rainfall were correlated with higher aluminium concentrations, which have been consistently rising.

Sulphur Content in Water

While there is no specific information about sulphur levels in Brunei's water supply, it is worth noting that sulphur is naturally present in water and plays a role in maintaining a healthy body. Alam Water, a natural mineral water brand in Brunei, contains sulphur and other essential minerals.

Brunei's water-related challenges

• Water Pollution: The Brunei River, a major freshwater source, has been affected by wastewater treatment plants, industrial discharge, and polluted streams. Point and non-point pollution sources, including residential, industrial, and agricultural outlets, are the main contributors. Domestic wastes and surface runoff constitute a significant portion of the pollution load.
• Limited Groundwater Reserves: Brunei relies heavily on surface water, with about 99% of its water supply coming from four river basins: Daerah Tutong, Kuala Belait, Temburong, and the Brunei River. While these rivers provide adequate water most of the time, extended periods of dry weather can lead to water shortages. Limited groundwater reserves have been found in some areas, but extracting groundwater is challenging due to the impermeability of the underlying rock strata.
• Population and Economic Growth: Brunei's increasing population and economic development are expected to put more pressure on water resources and quality. The country's industrialization and urbanization can further strain water sources and increase pollution levels.
• Water Management: To address water-related challenges, Brunei has implemented various measures, including constructing reservoirs and dams, utilizing hydrological data, and international cooperation. They have also proposed water conservation and sustainability measures, as well as new designs for riverside development and integrated water resource management plans.
• Climate Change: As a tropical country with high temperatures and rainfall, Brunei is vulnerable to the impacts of climate change. They have made initial progress in adapting to these threats, but it remains a challenge to ensure sufficient water resources and maintain water quality.
• Industrial Discharge: Industries, such as the liquefied natural gas industry, abstract and treat water from rivers like the Belait. Other industrial processes, including timber/sawmills, dairy farms, soft drink manufacture, and workshops, also contribute to water usage and potential pollution.

While Brunei has taken steps to address these challenges, ensuring a sustainable and high-quality water supply for its population remains a key focus for the country's future development.
