Water treatment: YAMAHA Clean Water Supply System

YAMAHA Clean Water Supply System improves people's lives in rural areas

Summary

Yamaha Motor Co., Ltd. is offering a Clean Water Supply System designed to supply clean drinking water in rural areas using sand filtration. With a solar PV system, the system can be installed and run without being constrained by accessibility to electrical grid. The system does not require high running costs, neither complicated installation nor maintenance. As a result, the system has already been implemented many places in Asia and Africa (16 units in Asia; 21 units in Africa) since 2003, showing significant improvements in sanitation and health conditions in installed places.

The Clean Water Supply System is also expected to change people’s lifestyle by reducing time spent for fetching water and improving productivity on work or study. It can also help to create new business opportunities in the community such as water delivery services, cleaning and ice-making.

Major Features

I. Low Cost
Compared to other technologies such as rapid filtration and membrane filtration, the running cost is cheaper as no coagulant or membrane filters are required.

II. Ease of Installation and Maintenance
We supervise local residents for installation work and train them for ongoing maintenance. The system is designed for simple installation and maintenance.

III. Duplicability
The system is highly duplicable for rural areas, whether an electrical grid connection is available or not, as long as there is a surface water source.

Technology Data

Conceivable Applications
The Yamaha Clean Water Supply System is a water purification system using slow sand filtration which is primarily intended to provide rural residents with clean drinking water. As most rural areas are not yet connected to an electrical grid, a solar PV system is available within the same package to provide the power source.

Competitive Advantage
The system has the following three advantages:

1.Low cost
Compared to other technologies such as rapid filtration and membrane filtration, the running cost is cheaper as no coagulant or membrane filters are required.

2.Easy installation and maintenance
We supervise local residents for installation work and train them for ongoing maintenance. The system is designed for simple installation and maintenance.

3.Duplicability
The system is highly duplicable for rural areas, whether an electrical grid connection is available or not, as long as there is a surface water source.

Purification flow

■ Key points regarding the slow sand filtration flow
– Water flow speed is slow (4-5 m/day)
– Sand must be uniform size (under 1 mm)

Technical maturity / Past record of introduction
The system has been sold since 2003. To date, 16 units have been installed in Asia and 21 units in Africa.

Conceivable risk
Technical risk: The quality of purified water could fluctuate and accidentally deteriorate due to weather conditions.

Security risk: There is a risk of theft of the high-cost solar panels and water pumps.

To mitigate the risks mentioned above, we train local users and residents to continuously monitor weather conditions and regarding how to implement theft prevention measures.

Business concept and anticipated benefits

A dependable clean water supply delivers significant improvements to lifestyles

The Yamaha Clean Water Supply System converts river or holding pond water into clean water. Access to clean water is known to improve sanitation and reduce the occurrence of ailments such as diarrhea and fever. Easy clean water access also saves time and labor involved in fetching daily household water from a well, pond, or river. Time can therefore be spent more productively on work or study. A clean water source can also change people’s lives in other ways, helping to create new business opportunities for the community such as 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.
