Well construction

Well construction

In 2006/2007 the master and   trainer Mr. Christian Schulz-Topel took up a suggestion   and carried out a well construction project with his trainees (sanitary technology) at the International Federation (IB) as part of the training.

Research in trade journals and the Internet has led to the trainees building a prototype well drilling rig with little financial     resources. This, purely mechanical device, was then successfully tested in 2007 in Berlin-Zehlendorf.

The construction is suitable for borehole depths of up to about 9 -10 m in a sandy ground. No motor drives are required for the bore. Pure muscle strength is enough!

As part of the meeting trip to Sierra Leone, November 2007, the well drilling rig was successfully used in rural areas by the tour group (10 participants). The demonstration and training at our (then) partner showed a great impact, a great interest and was crowned with success. After a two-day drilling, clear drinking water was found at a depth of 9 metres.

The previous solution, to fill water from a pond in canisters, leave it standing for three days and then drink the upper part, can be a thing of the past with this well. The well drilling rig was successfully used several times in the following period and modified by the (then) partner.

Another prototype was handed over to Milton Margai College in Freetown in 2011. This prototype was then handed over to the Youth Development Project (YDP) in Oogofarm in 2013.

Economically, our construction is of interest. Our   partners in Sierra Leone, Bishop Billy Symbol and John Pessima with his pastors of UBC, told us that a well construction there costs about 5000 dollars. Our construction, with its material value of approx. 500 €, is therefore a very good alternative. Commitment and muscle strength makes it possible to create a well with little effort
