Designing Water, Hygiene and Nutrition Businesses in Kenya

Jess Vechakul and her team kick off a new project in Kenya designing a scalable business model selling clean water alongside hygiene and nutrition products.

We, at, are so excited to be working again with Unilever and Water and Sanitation for the Urban Poor (WSUP)! We've conducted several previous projects with Unilever and WSUP –  including Ghanasan, where we designed the business, toilet, brand, and scale-up strategy for Clean Team, an in-home sanitation service that launched in Kumasi, Ghana. As part of this new project, our work will be reaching a whole new level with the Global Alliance for Improved Nutrition (GAIN) joining Unilever and WSUP as our partners.

The Project

How might we design a scalable business to sell water alongside hygiene and nutrition products? 

For many urban dwellers who do not have piped water at their homes, buying water from vendors is a daily necessity. There are also franchises and entrepreneurs selling a mix of consumer products door-to-door or at market and street stalls. The goal for this project is to create a service selling water along with health products. The location for our field research will be Nairobi, where WSUP has already helped entrepreneurs establish water kiosks.

By combining safe water sales with hygiene products (such as soap) and nutrition products (like food and vitamins), we hope to create synergies that will appeal to many customers and provide multiple health benefits. Safe water paired with easy access to soap and other hygiene products could significantly reduce diarrheal disease. Decreasing diarrheal illness and providing access to fortified foods and vitamins could be even more effective at combating malnutrition than implementing either strategy alone.

What's great about this project is that it addresses several critical health issues simultaneously while also creating opportunities for local entrepreneurs to increase their income. In order to maximize social impact, these business models must also be scalable and replicable so that the business can start local and eventually spread globally.

Our Research So Far

The team has spent the last week conducting secondary research on innovative business models and organizations supporting these local entrepreneurs and kiosks. Our first expert interview was with Living Goods, the “Avon of pro-poor products.” Living Goods recruits and trains Community Health Promoters (CHP) who go door-to-door, selling health products and educating their neighbors about malaria, diarrhea, and other common health ailments. Living Goods is a great social enterprise model for us to study because the company provides its CHPs with quality health products at a lower wholesale price so that the CHPs can earn a modest income while selling products that help their communities maintain good health. Before departing San Francisco at the end of this week, we’ll be designing prototypes inspired by the most promising business models that we've identified as part of our research. When we hit the ground in Nairobi, we’ll be equipped with research methods and prototypes to test out different services, from home deliveries to mobile salesmen to hybrid models that blend existing approaches. The team tackling this challenge is Robin BigioLiz OgbuEmily Friedberg, and me, Jess Vechakul.

Hi Jessica and others,

This sounds great. I have a question about your design challenge, because I am just learning and teaching myself as I go along. The methods say to phrase your design challenge in human terms, not organisational or product terms.

When you arrived at your design challenge, i.e. How might we design a scalable business to sell water alongside hygiene and nutrition products, did you discuss whether that was too product focused, maybe a more human focused question would be, How can we encourage people to buy sanitation and nutrition products at the same time as they buy their water? (sorry, thats just an example, obviously I dont full understand the project!).

In regards to being able to adapt this to my context. I am not sure how helpful it is, because when you are trying to improve a person's uptake of a product, it is clear on how you can prototype options and test them out. Because its a physical, tangible thing. What if the thing you were trying to develop was a maternity hospital, or even something less tangible, like a leadership program or youth service? Any ideas?

Great design challenge! I look forward to hearing more about the impact of this project.
