This study examined the spatial distribution of existing public water facilities within Osogbo municipality using Geographic Information System (GIS), GPS and Remote Sensing technology. This was with a view to generating baseline information for optimizing water supply and distribution systems in the city. Analogue water utility sketch map were scanned, geo-referenced, and digitized. Google Earth, Landsat 8 and ASTER GTM images of the study area, were used for various analysis in ArcGIS environment. Also, the land use land cover analysis was carried out to depict urban expansion that had taken place over the years in the study area. The analysis
revealed that the city had areally expanded beyond the coverage of the existing pipeline networks having covered just 21.5 sq.km (32%) of the present municipal area (67.07 sq.km). This indicated that if all the facilities are working maximally, only 32% of the total area would have access to water supply. The study therefore concluded that public water supply distribution system in Osogbo was far below meeting the Millennium Development Goals (MDG) on potable water supply in the less developing country like Nigeria. The study suggested suitable site locations, based on the suitability analysis for siting of water reservoirs for optimal water distribution in the study area.
