 In Waste Water Management Japan can Help India

Excessive stress was put on available water resources in India due to the growing population combined with a huge demand of water for development purposes.

From 813 billion cubic metres in 2010 the demand of water is set to reach 1,093 billion cubic metres by 2025 in the country.


Wastewater management is the only hope for a sustainable future.

And, India can adopt the Japanese way of treating wastewater.

Toshiba, a Japanese multinational engineering and electronics conglomerate corporation, is using the Whole Effluent Toxicity (WET) method on a trial basis as a new way of investigating the impact of wastewater from its production sites on the environment.

Toshiba Group carried out these tests at five production sites, including the Toshiba Yokohama COmples, which were chosen from among the various industries in which it operates.

No substantial impact of wastewater on the ecosystem was observed at any site.

Industrial units in India and elsewhere in the world can adopt this method.

"After we process sewage for waste water from our factory, the neutralized water is pumped up to this Biotape - we call it "Lagoon" in order to monitor safe water conditions and prevent harmful waste water before it flows to the sea. The pumped waste water flows to this machine to monitor the amount of Nitrogen phosphorous and COD for 24 hours operation," said Hiroshi Matsuzawa of the Toshiba Yokohama Complex.

In rural areas, where safe drinking water is not available, the Yamaha Clean Water Supply System has come as a boon.

In Indonesia, when Yamaha Indonesia Motor Manufacturing was established in 1974, there were many factory employees who lived in areas without clean water supply.

The company then set up Clean Water Supply System, an environment friendly water purification system, that adds modern improvements to slow sand filtration' method.

It uses no coagulant chemicals or filters and it has the capacity to purify 8,000 liters of surface water daily from rivers, lakes or ponds.

"It all began when Yamaha realized the need to improve the local water supply situation that Yamaha Indonesia Motor Manufacturing had established in 1974. This time we invited our clean water engineers to Indonesia from each country for training. During the training, engineers learnt about our clean water system. Also, we provided training for maintenance and basic troubleshooting," said Mihoko Totsuka of the Clean Water Group, Business Management Division, Yamaha Motor Co. Ltd.

In rural India, where people face an acute shortage of safe drinking water, the Yamaha Clean Water Supply System can help provide potable water.

Access to clean water can help improve sanitation and reduce the occurrence of ailments like diarrhea and fevers.
