Indonesia is a nation of 270 million people in southeast Asia composed of 17,508 islands (of which 6,000 are inhabited) which straddle the equator between the Indian Ocean and the Pacific Ocean.
The largest islands are Sumatra, Java, Borneo (called Kalimantan in Indonesia, which has sovereignty over about two-thirds of the island), Sulawesi, and New Guinea (eastern half). Other notable islands include Timor (eastern half), the Maluku Islands, and the Lesser Sunda Islands which include Bali
Indonesia is the 4th most populous nation in the world (after China, India, and the United States).
Its major environmental issues include:
- Water pollution from industrial wastes, sewage;
- Air pollution in urban areas; and,
- Smoke and haze from forest fires.
- Total Renewable Water Resources: 2,838 cu km (1999)
- Freshwater Withdrawal: Total: 82.78 cu km/yr (8% domestic, 1% industrial, 91% agricultural).
- Per capita Freshwater Withdrawal:: 372 cu m/yr (2000)
- Access to improved sources of drinking water: 80% of population
Access to improved sanitation facilities: 52% of population
Indonesia’s main water resources are:
- Surface water “is water from river, rain water, lake or fresh water wetland, which can be treated using different methods, such as Ultrafiltration Systems, Media Water Filters, Brackish Water RO.
- Desalination can be used for water from ocean, or sea source, which can be treated using Sea Water 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, Media Water Filters, Chemical Dosing, UV Sterilizers.
- Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water Softeners, Media Water Filters
Water Treatment in Indonesia
Indonesia’s rapidly growing population demands an equally growing quantity of water for consumption and other uses. However, the indonesians low access to freshwater and sanitation facilities has remained a major detriment to the country’s ability to develop. Less clean water lowers the chance of good hygiene in these communities and also increases the chances of waterborne diseases from arising.
