Introducing water purification system for rivers and ponds to improve sanitation and health

The environmentally friendly "Slow Sand Filtration" system

The Yamaha Clean Water Supply System is a water purification system that adds modern improvements to the "slow sand filtration method“. It has been used throughout history in many regions of the world. It is an environmentally friendly system because it uses no coagulant. Another advantage is its simple construction and easy maintenance. To start the sales of this product, Yamaha Motor conducted research and operational tests in Asia and Africa over ten years.

Surveys and monitoring projects in a growing number of countries

Yamaha Motor has installed the Yamaha Clean Water Supply Systems at six locations in five countries in Asia in order to conduct on-the-site surveys. It provided useful data for identifying more specific local needs and issues. It helped to improve the system. (As of Oct.2019)

All began when we recognized the need to improve the local water supply situation

When Yamaha Indonesia Motor Manufacturing (YIMM) was established in 1974, there were still many factory employees who lived in areas without clean water supply. This made us realize the need for improvements in the local water supply system, which would help our employees and local residents alike. It triggered the development of the Yamaha Clean Water Supply System. The families of employees from Japan working on assignment at YIMM complained about brownish tap water. The project was initiated to develop the water purifying system. That led to the release of the home use water purifier in 1991.

In order to improve the health and sanitation conditions for the people living in the areas without public water, the further efforts were made. The new larger system could produce clean water by using the abundant water resource from a local river. Based on the results of the pilot plants and the improved versions that followed, the Yamaha Clean Water Supply System was launched commercially in 2010.

Life can change with dependable clean water supply

A Yamaha Clean Water Supply System can change river or holding pond water into clean water. Access to clean water is known to improve sanitation and reduce the occurrence of ailments, like diarrhea and fever. It also saves time and labor for fetching daily household water from a water hole or river. Time can be spent more productively for work or study. A clean water source can also change people’s lives in other ways, helping create new business opportunities for the community such as water delivery services. Forming a committee to manage the water supply system can also promote self-government and self-reliance functions in the community.
