Tekyekrom
Tekyekrom is situated on the Dunkwa-Obuasi road. We will drill holes on 3 locations there. EcoSan Ghana already found water on Location 1, and we are currently drilling on Location 2, using the FloFlo.

The FloFlo
The FloFlo is an ancient drilling tool, modernised by dutchman Floris de Vos in 2011 (see Facebook page) 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 a manpowered drill tool. Anyone can do it, and it is cheap and efficient.

The First Phase
The crew started working on September 14, 2016 (Bismarck, Akwasi Adea, Kojo Amoah, Dominic Asante, Yaw Fosu). The kontihene (head of the elders in the village) stopped by for inspection and some motivational words. After 2 days they had drilled 13 feet deep. On the third day (16/09), at a depth of only 17 feet, water was found. Two more days of drilling gave way to a depth of 28 feet (19/09/2016). On location 2, after the first day (20/09) the hole was 8 feet deep. Then 16.4 feet (21, 22/09), 20 feet (23/09) and 24 feet (24/09) respectively.

Costs
The first phase on location 1 cost 5 days of work, 1250 cedi (€284,-). For the second phase, we need casing pipes. Thijs klompmaker bought 100 meters of casing pipe in China; total costs including shipment and bank transfer fee: €1,171.95. We need to wait to know the local (from Tema port to location) transport costs, after which we can calculate the total costs per meter (€11.72/m so far)
