ABSTRACT
Mapping is a very important aspect that provides effective planning, operation and maintenance in water supply and distribution networks which is one of the most essential components of urban infrastructure. It helps in unlocking the information and identification of the actual location of points and features above and beneath the earth surface. Developing a functional system to manage water distribution assist government in water revenue collection and provide effective service delivery in water utility organizations. The main purpose of this study was to provide a comprehensive map of Bauchi Urban water distribution system using GIS technique with the objective of updating the existing water distribution map, creation of functional geo data base for water utility billing, analyzing the spatial accessibility to the pipelines and identifying the places that require theextension . This study identified the problem of inadequate water distribution and irregular accessibility in the study area due to increase in population, poor facility mapping and inadequate information. The primary data was collected from interview, questionnaire, and field survey using hand held G.P.S and DGPS. Secondary data collected include the analogue base map, Pleiades (50cm) satellite imagery and ward population data from the concern organizations. Queries overlay and proximity analyses have been carried out together with the statistical analysis of the questionnaire and compute the amount of water required by the population of the study. The results presented the updated map and developed a GIS based integrate water utility billing system. Also, it analyzed the water accessibility using international and Georgia accessibility standard, and finally, validation test was conducted to ensure the accuracy of the result.
