Using geo-process wizards in ArcView software, 1 km buffers were created around the grid electricity
line. The buffer map was clipped from the administrative boundary map to obtain the areas that lie
outside the buffer area. Similarly, 0.5 km and 0.2 km buffers were created for the road network and
streams, and thus the areas far from the road buffer and nearer to the stream buffer were selected. Finally,
overlaying this theme with a household map (for households having low access to regular water supply),
suitable areas were selected based on areas that have less access to a regular water supply. Fig. 3 shows a
flowchart used for identifying the suitable areas.
