Modaso
From WaiWiki
EcoSan Ghana drilled for water in Modaso, Ghana, using a FloFlo drill tower (percussion drilling). The FloFlo is an ancient drilling tool, modernised by dutchman Floris de Vos in 2011.
The FloFlo employs a hoist using a three legged tower. The drillbit is repeatedly hoisted and released to pulvarise the hard soil as it hits the ground. Once a substantial amount of soil has been pulvarised, the drillbit is replaced by the bailer, equiped with a valve, to pull out the soil. Thus it is manpower driven drill tool. Anyone can do it, and it is cheap and efficient.
