An Excel-based water supply-demand model was developed to assess shortfalls in water supply in Funafuti and Vaitupu relative to the emergency, critical and longer term water security targets and to assess and to assess additional capacity required to meet the targets. Water supply and demand data from 2011 to 2014. Rainfall data from 1933 to 2013.

This resource was produced using funding provided by the Pacific-Australia Climate Change Science Adaptation Planning (PACCSAP) programme. The model was calibrated to reflect the current conditions in Funafuti and Vaitupu. This involved compiling datasets on: number of households and house sizes (both communities); household water consumption (both communities); household rainwater tank capacity (both communities); capacity of government & community cisterns (both communities); desalination capacity (Funafuti); and groundwater capacity (Vaitupu). The model was also supported by historic daily rainfall datasets for each of Funafuti and Vaitupu.
