Project description
Ngong is a town near the Ngong Hills within Kajiado County. During the years of British colonial rule, the area around the Ngong Hills was a major settler farming region, and many traditional colonial houses are still seen in the area. Today Ngong and its environs is a well-developed outskirt providing a good residing place for many of Nairobi's workers.
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.
