Abstract

Water supply system is a network of engineered hydraulic components which provide water supply to individuals and organizations. It has been noted that some areas experience shortage of water because of inadequate pressure and flows, illegal connections and leakages. This research focused to address the problem of pressure and flow variations at design stage. This is because the efficacy of a water supply system depends much on its design aspects. This was done through examination of key design aspects and generation of an algorithm for analysis and calibration of designs for water supply systems. The algorithm was developed to provide improvements and modifications until the intended standard is achieved. Interview and documentation analysis were the techniques applied for data collection. Analysis of data collected provided the foundation for model and algorithm design. Major principles considered were Continuity equation, Hazen William's equations and gravity-flow theory. The generalized model and the algorithm were implemented into software in order to make findings accessible while hiding unnecessary complexity to the user. Running time efficiency of the algorithm was found to be linear. Both the algorithm and its model proved to be correct through several tests done. Theories, principles and assumptions applied hold to be true for branched (tree or dead end) distribution systems. The prototype system provides a localized tool for design and analysis of water supply systems under local settings.
