Harvesting Rainwater with Rock Catchments in Kenya [2017]

In Marsabit County, Northern Kenya, Caritas Switzerland has, together with communities, constructed three rock catchment systems. In this region, there are no permanent rivers and the dry seasons can get severe. Moreover, not all groundwater sources are suitable for human consumption and people often rely on scarce and mostly unprotected water sources. Only about 35% of the population have access to safe water.
The rock catchments collect rainwater from large bare rock surfaces before it gets channelled to storage tanks. The three systems serve 3,500 people and can store a total of 2.34 million litres of water per rainy season. This covers for approximately three months of human water consumption.
