We host these builds to make our SAM3 Household Filters
, which are distributed for free by our Rwandan volunteers and staff in rural communities.
We use your volunteer labor to reduce the cost of the overall filter. We still need to purchase the materials, ship the components to Rwanda, and purchase the remaining materials (like sand and gravel) in-country.
Ultimately, the Rwandan people benefit from these events because the 10-year-plus filters, when partnered with several days of health and hygiene training, lead to not just dramatically improved health, but also increased income and education. When you're not sick you don't buy medicine at the health clinic, and you don't miss work and school.
