After completing a number of field interviews and some competitive analysis for the water filter program, there were a couple of key takeaways that can be applied to the water kiosk initiative.  The most valuable finding is that WaterGuard could be used to dramatically expand the capacity of each kiosk in a very cost-effective manner.  At only .67 shillings per 20 liters purified plus 3 shillings for the water, the kiosk could sell purified water for 5 shillings and still make an acceptable profit.  This assumes of course that at least 30 households in the serviceable area are interested in buying it daily, which I think is achievable with good marketing (says the marketing guy).  In fact, given the density of Kibera, there’s tremendous upside potential if the market interest is high.  The biggest advantage of WaterGuard is the low variable cost.  Unlike adding another filter, doubling or even quadrupling the water purified from WaterGuard is extremely affordable to the kiosk owner.

There are some risks that come with this new product, though I’m not tremendously concerned.  The first is that some people don’t like the taste when WaterGuard is used.  Again, given the density of Kibera and the very attractive price point (especially compared to the risk of contracting typhoid), I think we’ll find enough people who don’ t mind the taste.  For those people who really can’t tolerate it, we will still offer filtered water at the original 10 shilling price.  The extra 5 shillings might seem excessive, but I’m assuming a relatively small number of filtered water sales in the pro forma.

The second concern is that WaterGuard is already available and people could just buy it to purify their own water.  Honestly, I hope some do decide to do that.  We’ll even sell them the bottle.  However, I don’t believe everyone will take us up on the offer.  One might think that in this area of exceptionally high unemployment (or underemployment), there would be no premium placed on the time savings or convenience of having someone else purify the water.  It’s not purely a convenience issue, but people simply view purifying water as an errand they don’t enjoy.  As such, they often just skip it altogether.  With the kiosk model, they don’t have to spend 30 minutes on something they don’t enjoy.  They can just get the clean water directly.

The other key takeaway from spending so much time wandering around the town was how effective the Safaricom / M Pesa (same company) marketing strategy is here.  Kenya is seemingly sponsored by Safaricom.  They’re more ubiquitous than Starbucks in Seattle.  But instead of spending huge sums of money on television commercials, they simply paint their 11,000 agent stands bright green and have easily recognizable signs at every one.  While that might sound obvious, they’re one of the only companies I’ve seen who do that here.

I love the idea of replicating this approach for the water kiosks.  It really won’t cost very much money per kiosk, but the cumulative effect will be very powerful.  It compensates for the fact that no individual kiosk owner will earn enough to invest in serious advertising, and the likelihood that they would otherwise pool together funds for marketing is slim to none.

This model also mitigates one of the biggest weaknesses of projects launched by foreign aid groups.  Often a foreign group will come in, do a huge promotional push, and then eventually move on to a new area or project.  Things are going great when they’re there doing the promotion, but as soon as the group leaves, everyone forgets about it and goes back to their old habits.  I think that’s probably one reason why so few people are using WaterGuard here.  Nobody is promoting it.  With the kiosk model, there’s an omnipresent, visible leave behind to keep the service top of mind.

The one negative development is that I’m struggling to find a micro-finance institution that will return my messages.  I’ve been told from a trusted source in the industry that MFIs are constantly flooded with these types of proposals and that the likelihood of them meeting with me is low.  I have two potential solutions to this problem, so hopefully at least one of them will work.

Overall, I’m still very excited about the potential for the water kiosks to seriously broaden access to clean water in the slums as well as other areas in Kenya.  I will continue to write updates as new developments arise.  I’ll keep asking for your comments, despite the fact that I receive very few.  I’d love to hear your thoughts and suggestions.

I mentioned in yesterday’s post that you really need to dig to uncover the truth in the field interviews. There’s a powerful combination of people wanted to give the “right” answer, people assuming the Mzungu knows best, and people thinking that maybe they’ll get something for free if they express interest. Today I had a bizarre conversation with a woman who knew we were from the water filter plant that basically went like this:

Do you treat your water today?
– No. Nobody is sick and the water is clean
Are you familiar with WaterGuard? Have you ever tried it?
– No . There’s no need. The water is safe.
So would you be interested in purchasing a 1,500 shilling water filter?
– Yes, I would very much like to purchase a filter
Why? You said the water is clean and no one is sick.
– I’d want it as a precaution. The water would be safer if I purify it.
In that case, why don’t you use WaterGuard as a precaution today?
– I don’t know. How much does it cost?
20 shillings treats your water for a month
– Wow, very exciting! I didn’t realize that.
So will you start using WaterGuard tomorrow as a precaution since the filters aren’t ready?
– Silence.

Actions speak much louder than words. Even with these challenges, I’m still learning quite a bit from these interviews. I’ll have another post plus a bunch of pictures over the weekend, so be sure to check in.

Kenya Village Interviews

After a second day in the village of Mbai, I’m starting to see some trends related to the four key research questions.  Of course this is just one village, so we’ll conduct interviews in other villages as well as the urban areas around Kitale over the next week to further validate the findings or see how answers differ in other regions.  I won’t mention every key finding here, but I’ll list some of the highlights.

1. Develop an understanding of the needs/demands of the community regarding drinking water

  • Every household we interviewed gets their water from a public source like a stream or a well.  Nearly everyone recognizes the need to purify water, often because they were told to by a doctor after contracting typhoid.
  • The overwhelming  common theme throughout each interview was price.  When people didn’t purify, it was often because they felt it was too expensive.  When people did purify, they complained that it was too expensive and said they would be very interested in anything that reduced the price.  Interestingly, there are commercial products like chlorine solutions that are far cheaper than the most common method of boiling, but many people didn’t actively search out these lower cost alternatives despite their desire to cut costs.  For the filters to be sold effectively, we’ll need adequate promotion to make people aware of the benefits like long-term cost effectiveness.

2. Determine competition / alternatives to water filters and their pros and cons

  • There are three clear alternatives in this village; boiling, using chlorine (WaterGuard), and drinking contaminated water.
  • Boiling is the most common method, and also seems to make the least amount of sense.  It takes up to 30 minutes to boil and then cool the water.  It’s the most expensive option if you don’t have wood on your property and have to buy firewood as many do.  It’s also bad for the environment, though I don’t think that’s a factor for most people.  However, it’s simply the most familiar to people and it’s easy to understand.  While it’s not cheap (20 shillings worth of firewood can boil 20 liters of water), it’s certainly an amount most people can raise every day.  There are also no side effects in terms of bad taste or the fear of unknown chemicals.
  • WaterGuard water purification solution

    WaterGuard water purification solution

WaterGuard is a chlorine solution that some people use.  It’s extremely cheap, with a 20 shilling bottle supposedly purifying 600 liters of water.  The main problem with WaterGuard is that people don’t know about it or assume it’s expensive.  Many people looked shocked (in a good way) when I told them about WaterGuard.  Another problem is that you have to let the water sit for 30 minutes after you add the chlorine.  Most people here don’t have watches and some don’t wait the full 30 minutes.  Lastly, some people say it gives water a bad taste and smell.  I bought a bottle, and plan to test it out this weekend.

  • Of course drinking contaminated water is both fast and free, right up until you contract typhoid.  Then it costs upwards of 3,000 shillings for treatment plus lost wages while you’re recovering.

3. Determine a price people will be willing to pay for a filter

  • The key finding here was the overwhelming request for the ability to purchase the filter in installments.  Most realized that even at 1,500 shillings, the filter was cheaper than firewood over a long period of time, but they didn’t have that kind of money to pay up front.  Having flexible terms was important, as some wanted to pay 500 shillings over 3 months while others wanted to pay 100 shillings over 15 months.  One person said he’d prefer to just make payments whenever he had money available.

4. Determine viable distribution channels for filters

  • The first common theme that emerged here was that they wanted to buy the filter from someone they knew, especially if they were buying it in installments.  Nearly everyone went to the market in Kiminini once per week and knew many of the vendors.  They said that would be far better than buying it at a large store where they didn’t have a personal connection with the staff.
  • The second request, consistent with the first point, was to sell them close to where they live.  Public transportation is not great here, and traveling a long distance with a fragile filter would not be ideal.
  • This topic in particular will be interesting to compare across geographic regions.

I’ll write another post and put up more pictures over the weekend, so be sure to check back soon.  I’ll also try to get in a fun, non-work related post with pictures if possible.  In the meantime, enjoy some new pictures below and on Flickr.

Day 1 of the field interviews is now complete and after 6 interviews, there were some interesting findings.  One issue that I somewhat expected, but not to the extent I saw it, was the tendency for people to tell me what I wanted to hear instead of what’s really happening.  There were numerous instances where people would contradict themselves during the interview.  When I questioned them on the inconsistencies, I would often find the truth to be very different from what they first told me.  Here are a few examples.

  • One woman told me that she used to use WaterGuard, a chlorine solution, but stopped because it was too expensive.  When I asked how much it cost, she said she didn’t know.  She eventually told me that her daughter used to buy WaterGuard, but since her daughter moved to a different town, she really just never thought about buying it herself.
  • Another woman told me that she usually boils water, but occasionally uses chlorine tablets.  When asked about the price, she said firewood for boiling 20 liters of water costs 20 shillings.  Chlorine cost 40 shillings for a 20 pack of tablets, each good for purifying 20 liters of water.  I asked why she didn’t use the chlorine tablets more often, and she said they were too expensive.  When I pointed out that per 20 liters of water, tablets were 10x cheaper, she then said that she actually doesn’t buy firewood, but rather goes on long walks to collect it from the ground.
  • Every person told me they believe their drinking water source is not clean and would pay up to 1,500 for a water filter.  Several said they have gotten typhoid, which cost 2,000 – 3,000 shillings to treat.  Yet many of these same people said they don’t currently purify their water because it’s too expensive.

Fortunately, there were some valuable findings.  Please note that all 6 of the women interviewed were from the same village, in the same widow’s club.  They were also on the more extreme end of the poverty scale.  Over the next several days we’ll interview people from other areas to get a more representative sample.

  • Nearly every woman said they would be extremely interested in buying the filter in installments.  Most know the vendors in the local Kiminini market, and would feel comfortable paying anywhere from 100 – 500 shillings per month for 3-10 months until they’ve saved enough to take home a filter.  They would not feel comfortable paying in installments with a vendor they did not know, and all but one said they would have no interest in the filter if they had to pay for it in full.
  • In this group, most preferred to buy the filter as opposed to the water kiosk model because it’s ultimately cheaper.  Some were also afraid there would be days they didn’t have the 5-10 shillings to purchase water, or that they might forget to buy the clean water.  Many did say that if that they preferred the water kiosk model to their current behaviors of boiling or drinking unfiltered water, but buying the filter in installments would be their first choice.
  • Their financial situations are dramatically improved during the harvest season (Sept – Dec).  That is when most of them make any big purchases.  If we are going to spend resources promoting the water filters, it likely makes sense to do it around September or October.  Many said that even if the filters were ready now and they wanted to buy them, they simply couldn’t at this time due to lack of funds.

It will be very interesting to see how answers differ as we meet with people from different areas and slightly higher incomes.  I will post updates in the next day or two.

Also, be sure to check out several new pictures on Flickr.  I have pictures of the village and of the market in Kiminini.  Pictures of the water filter factory will be up soon.

This week I’ll be kicking off a very exciting market research project.  Working with a team of four Kenyan university students, we’ll conduct a series of focus groups and in-home interviews.  I’ve developed a 36 question survey to gather information on four critical research objectives:

  1. Develop an understanding of the needs/demands of the community regarding drinking water
  2. Determine competition / alternatives to water filters and their pros and cons
  3. Determine a price people will be willing to pay for a filter
  4. Determine viable distribution channels for filters

I’ll be posting interesting insights from these interviews over the next few weeks, so stay tuned.  If anyone is interested in seeing a copy of the questionnaire, just let me know via e-mail or a by posting a comment and I’ll send it over.

Over the past several months, I’ve come across several articles and books that have been extremely informative regarding the topics of clean water and financial services in third-world countries.  I’d like to share them both as a resource for current and future volunteers, as well for anyone else who might be interested in learning more on these topics.  Some PDFs are large files, so I’ve just listed the URL.  Over time, I may add to this list, so feel free to check back occasionally.

I wanted to share some details about an incredible program called Kick it with Kenya.  One of the biggest challenges to educating people in rural, developing areas on the benefits of safe water is not being able to reach large numbers of people at once.  There are no television commercials, no magazine ads, and very few large organized events.

To get around this problem, we’ve started planning the second “Kick it with Kenya” inter-village soccer tournament.  Soccer is one of the few activities that can draw a crowd, and we have some lofty ambitions.  This year, we’re planning to reach roughly 16,000 people in over 40 villages.  At each of the 40 regional games, we expect over 300 people to come watch.  That presents a perfect opportunity for us to conduct educational seminars about critical health issues like clean water, distribute medicine and conduct HIV testing, and promote and sell water filters.  At the finals in the larger town of Kitale, we expect around 3,000 people to attend!  Opportunities to reach this many people in this region are extremely rare.  Keep in mind that if we can educate one or two people from a household, the benefits will reach the rest of the people in the household.  With an average household size of 8 people, that means we can potentially impact over 100,000 lives with this event.

As you might imagine, this event is not easy to pull off and is certainly not free.  The total cost of the tournament is roughly $13,000, and we have very little time to raise the funds.  If you’d like to help, your donation would be deeply appreciated.  Here are some of the ways your donation could help:

  • $1,500 pays for the total salary, transportation, and promotional materials costs to demo the water filters and provide educational seminars at the 40 soccer games.
  • $800 provides a water filter for each of the 40 teams so the players can drink clean water while they practice and play in the tournament.
  • $350 pays for the promotional materials at the finals, where we expect to reach 3,000 people.
  • $13,000 pays for the entire event – and I’ll buy you dinner at almost any restaurant you choose.  I’m pretty sure a plaque or small statue could also be arranged.

My name is Jeremy Farkas and I will be traveling to Kiminini, Kenya from April 21 – June 2 to work on an initiative  promoting broad access to clean water.  I’ll be working with a local organization called Common Ground for Africa.  CGA has developed a plant to create ceramic point-of-use water filters dipped in colloidal silver that removes ~99.9% of harmful bacteria and viruses.  I was introduced to CGA through a fantastic seattle-based non-profit called Village Volunteers.
