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.
