Problem: What problem is this initiative trying to address?

Sambuko upward Gravity Flow Water, yielding 18 l/s translated into 1,555,200 l/d is very old and weary, serves 20,631people and 23,342 by 2020, no water user fee is collected hence no funds for rehabilitation. The design does not adequately meet the demand yet water escapes from the spring intake. Bacteriological results show prevalence of bacterial and fecal contamination coming from poor pit latrines near the open spots on the water system.

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

The solution is to refurbish the entire water system and engage communities to actively participate in management and maintenance through a sustainable friendly enterprise plan. A major system repairs and extension of services to areas without water is recommended, improvement of the spring source, fix pipe leakages and a structured system operation construction of an extension and maintenance. Use of sea sand to purify water is economical and will be demonstrated and applied by beneficiaries. Construct ecological sanitation toilets with both environmental and economical benefits to help solve poor sanitation problems. Conduct participatory community development campaign and WASH training to stakeholders for sustainability. Profile the upward gravity flow water scheme and market to tourists and geography students to create revenue to support the scheme.

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

Since Jane 2013, we organized and mobilized community members to use available resources to repair and maintain the old weary water scheme. We have approached higher authorities to give us the mandate to rehabilitate and manage the resource. We have taken a second needs assessment to that of local government from our organizational funds. We have mobilized communities to actively participate by offering free way of passage for the new pipelines and cheap labour. We have acquired skills of using sea sand as a water purifier instead of expensive chlorine used by others and will translated to stakeholders. Availability of clean water will reduce current risks of cholera, dysentery, malaria and other water born sickness. The proposed taxed revenue created will attract government to improve infrastructure for economic growth. Construction of econ-san will reduce expenses on fertilizers

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

We contribute 20% of our funds and stakeholders contributes (10%). We raise money from a micro credit scheme, sales from agriculture produces, and membership fees. With no grant for that work to carry out major repairs , our long term financial sustainability is to raise revenue by marketing a profiled scheme to tourists and geography students to create revenue, a user fee and sales from eco-san products to train Maison for future maintenance.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

Creative, Inclusive, Enterprising, Adoptive and Sustainable.

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

We have worked hard with clear vision and great confidence on the initiative. However, to our challenges, we are so determined to achieve our objectives. We want to stand out by achieving our goals. We therefore commend Nestle for the avenue to create shared value. We are happy to participate in this exciting opportunity

Water Contaminants. Bacteriological results show prevalence of bacterial and fecal contamination from poor pit latrines near the open spots.


No soakage pit for waste water and therefore there is ponding around the tap stands which increases prevalence of mosquitoes and malaria.

Gate valves for the washout on the existing collection chamber are not functional. Padlocks on the collection chamber continuously stolen. The lockable manhole is open at times which leads to different organic material falling into the collection to distort the water quality.


Loose main transmission pipe that hangs up across most seasonal rivers usually break during heavy rain floods and landslides.

To solve a local problem is always appreciated and it should be the primary aim for all of us. Next step is to go for system development which is sustainable. Instead of reverse gravity flow only you can think of rainwater harvesting which will reduce concentration of contaminants. I shall be happy to be associated with your community.

Thanks RAJIV GUPTA, Yes rainwater harvesting can be good but our situation is rehabilitating already existing system. You will be welcome to share with us more innovations on how we can improve our community water for good health.
