In the past years both Practica Foundation as well as Project Maji have been exploring ways to close the gap between operational expenditure and income in water projects focused on rural Africa, in the interest of financial sustainability of each water point. One of our key questions is whether a different approach to hardware design and hardware seup can bridge this financial gap. Therefore, both parties decided to partner and pilot a novel modular building approach in water hardware implementation. This report details the findings from our joint pilot rolled out in Ghana.
