River basin and water resources

 

In Japan, there are more than 2,700 river basins. Among them, 109 rivers are designated as being managed by the central government in principle because of their major importance to the economy and to the protection of the environment. The catchment area of these Class A rivers covers about 239,900 km2. Class B rivers consist of the other rivers which are managed at a lower level. 

 

Lakes and dams

 

More than 600 lakes are scattered among the seaside districts and the volcanic zones. The major lakes in the country are: 

• Biwa-ko, which lies in the inland basin near Kyoto in central-west Honshu with an area of 674 km2 and a water volume of 27.5 km3; 

• Kasumi-ga-ura, which is close to the mouth of the Tone-gawain with an area of 220 km2 and a water volume of 0.848 km3; 

• Inawashiro-ko, which is a lake created after a volcanic eruption in northwest Honshu with an area of 104.8 km2 and a water volume of 3.86 km3. 

 

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 cost-effective solutions and high quality water filtration based on the Japan's water resources.

Japan'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 Water 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 solutions in Japan
While Japan’s modern society consists of extremely comfortable lifestyles and services, the growing issue of water shortage is compromising the quality of life. As water supplies reduce in availability, the daily activities of the people such as making meals, flushing toilets, industrial operations are suspended. Farmers are forced to save water through means of sharing water, which although has conserved a percentage of water, still remains insufficient in maintaining enough water for consistent crop growth. Pure Aqua develops and distributes water treatment systems or the purposes of remedying these current issues existing in Japan.

Pure Aqua manufactures water filtration systems in Japan that meet the World Health Organization requirements.
