Evolving water point mapping to strategic decision making in rural Malawi

There is a need to evolve from the simple mapping of water points, now often numerous, to effective decision making using these data. This paper outlines new developments of mWater as the preferred online Management Information System (MIS) tool to analyse significant volumes of water and sanitation data in Malawi. mWater exemplifies an evolving strategic decision-making tool used to formulate rural water supply investment strategies. A time series of 25,000 water points have been mapped since 2011 to build a complete asset register of water infrastructure to support government endeavours to reach Sustainable Development Goal 6. This comprehensive live database allows real-time analysis of over sixty variables, including linkage to concurrent mWater sanitation and waste data. This paper briefly illustrates several emergent uses of the facility to exemplify its potential in strategic decision making using Big Data. It is currently being rolled out across the entire country.
