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 that has been used throughout history in many regions of the world. It is an environmentally friendly system because it uses no coagulant chemicals or filters, and it has the capacity to purify 8,000 liters (enough to supply a community of 800-1,200 people for 1 day) of surface water daily from sources such as rivers, lakes or ponds. Another big advantage of the Yamaha Clean Water Supply System is its simple construction and easy maintenance.

It all began when we realized 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 an improvement in the local water supply system which would help our employees and local residents alike, leading to the development of the Yamaha Clean Water Supply System.
- When the families of employees from Japan working on assignment at YIMM complained of brownish tap water, a project was initiated to develop a water purifying system. That led to the release of a home use water purifier in 1991.
- Further efforts to improve the health and sanitation conditions for people living in areas without public water systems led to the start of development of a system to produce clean water from the abundant water resource of a local river. Then, based on the results of pilot plants and the improved versions that followed, the Yamaha Clean Water Supply System was launched commercially in 2010.
Life can change with a 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 fevers. It also saves the time and labor of fetching daily household water from a water hole or river so time can be spent more productively for work or study. A clean water source can also change people’s lives in other ways, such as helping create new business opportunities for the community like water delivery services, cleaning, and ice-making. Forming a committee to manage the water supply system can also promote self-government and self-reliance functions in the community.

Business schemes to spread use of Clean Water Supply Systems
There are a number of different business schemes/strategies that can be used to install and operate Yamaha Clean Water Supply Systems. Partnerships can be formed between a variety of different funding organizations and owners/operators from both the public and private sectors (shown below) for the betterment of local villages, hospitals, and schools. Working together in cooperative partnerships with the communities, these stakeholders can establish clean-water businesses that will benefit all.
