Summary

The Water Crisis in Uganda

The East African nation of Uganda faces a significant challenge with 12.4 million people, over a quarter of its population, lacking access to clean water, predominantly in rural areas. This scarcity forces individuals, especially women, to travel long distances for water, exposing them to risks such as rape and snake bites.

Subo Aya's Initiative and the Sunda System

Subo Aya, a Japanese woman, has dedicated herself to addressing this issue by fostering collaboration between rural Ugandan communities, local engineers, and Japanese technicians. Her efforts are centered around a revolutionary payment system for water wells called "Sunda," the local word for drawing water.

Development of the Sunda System:

Subo established a local office in Uganda and partnered with Ugandan engineers.
Over six months, they developed the Sunda system, which utilizes ID chip tags distributed to each household.
Users top up their accounts via mobile phones, and the balance is loaded onto the ID chip.
By touching the chip to a sensor at the well, users can draw the amount of water they have prepaid.

Key Features and Benefits of Sunda:

Cashless Operation: Eliminates the risk of embezzlement of collected funds.
Fairness: Users pay only for the water they consume, addressing the inequity of fixed charges that did not account for varying household needs (e.g., number of members, livestock).
Sustainability: Revenue generated through the pay-as-you-go system is used to fund repairs and maintenance of the wells.

Technological Advancements and Expansion

The Sunda system was further refined with the assistance of automotive engineers in Japan. Since its implementation in 2018, over 300 Sunda units have been installed, providing clean water access to approximately 90,000 people. The revenue collected has successfully funded repairs for more than 300 wells.

Growing Support and Future Vision

Subo's initiative is gaining traction in Japan. Tachihara Taiga, an organizer of networking events for investors and entrepreneurs, is promoting canned mineral water, with a portion of the profits supporting Subo's work in Uganda. Each label carries a message highlighting the water situation in Uganda, aiming to raise awareness.

Key aspects of growing support:

Networking Events: Events are organized to connect with individuals in various fields, including music, culture, and the apparel industry.
Online Collaboration: Subo and Tachihara hold regular online meetings to strategize support efforts.
Passion-Driven Collaboration: Tachihara expresses enthusiasm for working with Subo due to her passion, which motivates him to work harder.

Subo's immediate goal is to expand the Sunda system to refugee settlements within Uganda and subsequently to other African countries. Her success is attributed to earning the trust of the local communities.

Notable Quotes

Subo Aya: "They need to use this kind of uh very dirty water from swamp. Of course that causes uh diarrhea and other diseases a lot. We are uh looking for uh future collaboration uh with you to solve the water issue and also health challenges."
Subo Aya: "If you only use a little water, then you only pay a little."
Tachihara Taiga: "You are connecting with people I could never reach on my own through my usual activities. I'm really happy that more people are finding out about Sunda. It's exciting for me to work with someone with real passion. It makes me want to work harder, too."

Conclusion

Subo Aya's Sunda system represents a significant advancement in addressing the clean water crisis in Uganda. By leveraging technology, community engagement, and international collaboration, the system provides a fair, sustainable, and efficient solution for water access and management. The growing support and Subo's ambitious vision for expansion underscore the potential of this initiative to transform lives across Africa.
