Sand Dam Technology.
Sand dam concept is a simple, low-cost, low-maintenance rainwater and groundwater harvesting technology.

Problem: What problem is this initiative trying to address?
East Pokot has a population of 166,000 and less than 10% are in permanent homes while the 90% live in stick houses which are temporary homes because of pastoral migration in search of pastures and water. East Pokot has experienced prolonged drought and inter-ethnic conflicts for the last 6 years and as consequence, deaths are commonplace. World Vision Kenya describes it as one of the worst situation in the last 19.5 years. Women and children are
Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?
The proposed solution is sand dam technology. The beauty of this technology is that it seeks to bring adaptability to unfavorable climatic changes across the globe. Sand dam technology is the most sustainable model of rainwater harvesting in drought-prone regions since it has virtually zero maintenance cost. It is technology that seeks to enrich the water table of an arid area over time by storing water in the sand hence preventing the extreme rates of evaporation in such regions. An example of Natan village in East Pokot Sub County in Kenya provides proof of the viability of this technology. Since the implementation of this technology in Natan, 1000 households immediately settled in Natan Village, approximately 100,000 livestock benefited from the available water source and a projected population of 5,000 Pokots’ are expected to permanently settle in Natan.

Savinglives: By December 2016, 90% of water sources in East Pokot dried up. Migration started in search of pastures and water. On January 10 2017, Kenyan President declared drought a national disaster. Families migrated towards Natan village. Natan is the only place with Sand Dam harvested water. Food security: Introduction of a 40 Acre community drip irrigation resulted in the transformation of 587 households from being pastoralists to full-time farmers. Promotion of education: Impact of the Natan sand dam was access to clean water for people, livestock and farms. Natan primary school has been born from the sand dam success. 60% of Pokot children never attend school. Literacy rate is 4%. Local ecology transformation: The water held behind the dam spreads horizontally creating a permanent increase in the water table, allowing trees grow naturally and transforming arid lands into farms.
Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?
Sand dams require no maintenance and are sustainable with minimum effort. Sand Dam technology also depends on community involvement. This is a basic requirement for all successful and sustainable projects beyond funding period. Community participation in design, implementation and sustainability of sand dam structures eliminate the need for continued financial support from donors. Our plan is to empower Natan people to understand the co
Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?
Sand Dam technology is affordable to mass poor and best for drylands and volcano belt areas.
Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.
In 2014, HAO and Rotary Club of Port Orchard, USA, undertook a pilot project focusing on equitable community access to safe water, improved sanitation and hygiene and community ability to develop and maintain sustainable water and sanitation systems. The project targeted pastoral communities.It is discovered that80-90% of the rivers there are seasonal and 70-80% of water facilities dry up each dry season. Underground water harvesting in regions along Rift Valley exhibits high-risk factor of up to 90% due to active volcano activities. Local communities lack skills and resources necessary to maintain operationalization of already drilled boreholes and 1 of known 7 boreholes drilled in East Pokot according to information from County Officials
