Spinhoven, C. (author)Handpumps are the main source of clean water for poor rural areas. Most of these pumps are maintained and managed locally. Unfortuantely this management model has proven ineffective leaving roughly 30% of handpumps out of order. Our vision is to improve handpump sustainability by moving maintenance and management responsibilities to the private...master thesis 2016

Oldenmenger, A.W. (author)To counter the effects of carbon dioxide emissions and to become less dependent on energy imports, the electrical energy production in Europe is likely to make a significant shift towards renewable energy sources in the coming years. One of the major challenges in this transition process is to match the unpredictable and fluctuating supply of...master thesis 2013

Van Overloop, P.J.A.T.M. (author), Negenborn, R.R. (author), Weijs, S.V. (author), Malda, W. (author), Bruggers, M.R. (author), De Schutter, B. (author)Unlike mountainous areas, lowland areas have limited potential to generate energy from water flows. Instead, for water systems in lowland areas that continuously need to pump water out of the system, the focus should be set to saving energy in the present water management. This paper gives an introduction into possibilities to manage water...conference paper 2010

Tacke, J.H.P.M. (author)A mathematical model describing the essential features of hydraulic ram operation is developed in order to clarify the possibilities and limitations of the ram relative to its site and its adjustments. The model distinguishes three different periods in the pumping cycle of the hydraulic ram: acceleration - retardation - recoil. Making use of the...report 1988

De Jong, P. (author)This report is the result of a project, called "comparative tests on commercial and newly designed waterrams", carried out by the Delft University of Technology and the Foundation of Dutch Volunteers in Rwanda. The aim of this project was twofold: - to test new, and cheap (i.e. locally constructable and maintainable) types of hydraulic rams, -...report 1988
