The Problem

Many of the local subsistence farmers who live in the rural countryside of Nicaragua often find themselves without easy access to a safe water source in their home.

The Solution

Collaborating with the NGO El Porvenir, we provided the necessary funds to build small biosand filtration systems in several homes in the region.

    • The filter systems are built using layered sand, gravel and charcoal in order to filter out impurities from stream or rain water. Essentially, this is a simplified version of what our planet does naturally to recharge deep aquifers and well water! The team members of El Porvenir work with the families to provide education on the use and maintenance of the system, in order to ensure they will continue to have clean water in their homes.
