We disseminate so called SMARTechs, being Simple, Marketbased, Affordable, Repairable Technologies like manual well drilling, EMAS en Rope pumps, Tube groundwater recharge, household water filters etc. An example is the rope pump, a simple hand pump: 130.000 installed worldwide. However a lesson learned is, "Simple is not easy". There were many failures due to construction errors and the wrong introduction of this pump. Also simple technologies need to be of good quality and need good management. That is why we started SMART Centres, WASH training centres in Tanzania, Malawi, Mozambique, Zambia and starting in 5 other countries. These centres train the local private sector in technical and business skills. We think that building local capacity in affordable WASH technologies and approaches is a very, if not the most cost-effective way to reach SDG6 in rural areas but also to reach related SDGs for poverty, food and employment.
