Reverse Osmosis & Water Treatment in Brunei


Brunei lies in Southeast Asia, on the northwest coast of the island of Borneo. It is bordered on the landward side by Sarawak, one of the two eastern states of Malaysia. The country consists of two enclaves separated from each other by the valley of the Limbang River in Sarawak. Brunei is divided into four districts with a total area of 5770 square kilometres.
The Water profile of Brunei is dominated by the use of surface water, which provides over 99 percent of the water utilised for all purposes. There are four major river basines in Brunei: the Temburong, Belait, Tutong and Brunei basins; the largest of these watersheds within Brunei is the Belait River basin. Brunei has two large dams which impound the majority of the stored water within the country.
The total rainfall was 2654 millimetres (mm) in 1994. There area two rainy seasons: from September to January and from May to July. The average precipitation in the nearby city of Kota Kinabalu (Sabah, Malaysia) is 2691 mm and this could be considered as a reasonable estimate for the average precipitation in Brunei.
Water resources
There are four principal river basins in Brunei: Temburong, Belait, Tutong and Brunei. The Temburong, the smallest of the rivers, drains a catchment area of about 430 square kilometres.
The Belait is the largest basin, with an area of 2700 km2. The lower catchment comprises an extensive area of peat swamp forest. The river narrows at the town of Kuala Belait and a sandbar restricts the discharge of water to the South China Sea. Some areas in the upper catchment have been cleared for agriculture.
The Tutong Basin, which is about 1300 km2, has a complex estuary system formed between two sand spits. Subject to fairly high tidal influence, its lower catchment is mainly floodplain. The upper catchment is jungle with patches of agriculture.
The Brunei River flows into Brunei Bay. The upper reaches of the river are a major freshwater source particularly for the western part of the country.
By analogy with the rest of the island of Borneo, the runoff coefficient is estimated at 1.5 m/year corresponding to a surface flow of 8.5 cubic kilometres. Limited reserves of groundwater have been identified in the Sungai Liang and Seria areas of the Belait district and in the Berakas area of the Brunei-Muara district. The estimated safe yield is 17.3 million cubic metres/year. Also by analogy with the rest of the island of Borneo, the total groundwater resources are estimated at 0.1 cubic kilometre/year, all being drained by the rivers.
The World Bank reports that at least 80 countries have water shortages and 2 billion people lack access to clean water. More disturbingly, the World Health Organization has reported that 1 billion people lack enough water to simply meet their basic needs, unfortunately in many countries water is scarce or contaminated.

Pure Aqua provides wide range of filtration and economical solutions based on the Brunei Darussalam’s water resources.

Brunei Darussalam’s main water resources are:

  • Surface water is water from river, lake or fresh water wetland, which can be treated using different methods, such as Ultrafiltration Systems, Brackish Water RO.
  • Desalination can be used for water from ocean, or sea source, which can be treated using Seawater Reverse Osmosis Systems; Desalination Systems.
  • Ground Water or brackish water is from water located in the pore space of soil and rock “Borehole well”, which can be treated using Reverse Osmosis Systems, Chemical Dosing, UV Water Sterilizer.
  • Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water Softener System, Media Water Filters.

Pure Aqua manufactures water treatment systems that meet the World Health Organization requirements.

Pure Aqua has over 20 years of experience as a global provider of B2B water treatment solutions for a variety of applications and industries, we offer a large selection of all types of reverse osmosis and water treatment systems to meet your industrial needs.
