Project description
Nzavoni is located within Makueni County, a county in the former Eastern Province of Kenya. The main economic activity in this area is sisal farming. Most residents of the area work at the sisal plantation while others have small business and do manual tasks in order to earn their income. Currently, locals have no nearby access to water but rely on piped water which is located at specific water points.
How we reuse water
Groundwater wells located near the ocean often encounter saltwater intrusion as they pump more and more water. As a result, water that was once fresh can become salty and undrinkable over time and require treatment. Because desalination requires significant electricity to run high pressure pumps, solar energy is an ideal way to generate ‘off-grid’ energy that is both reliable and cost effective for desalination. This allows groundwater that would otherwise be unuseable to become a reliable source of additional water.
