ASSESSMENT OF WATER SUPPLY DISTRIBUTION SYSTEM PERFORMANCE: IN THE CASE OF ADDIS ABABA SCIENCE AND TECHNOLOGY UNIVERSITY
In this study, Addis Ababa Science and Technology University (AASTU) water distribution system of existing supply system was assessed. The main objective of this study is to asses performance of water supply distribution system and recommends improvement measures for existing system, Water GEMS software was used as tool to model water distribution system analysis. The modeling effort included both hydraulic and water quality modeling. Simulation results for maximum and minimum pressures were used as base tool to evaluate the hydraulic performance and simulation result for minimum residual chlorine were used as base to assess water quality transformation in distribution systems. Modeling results showed violation of maximum and minimum pressure requirements. Along with this, water quality simulation results illustrated water quality was good due to availability of better residual chlorine which is meet WHO guideline. The model analysis result shows the different problems of the system. These are undersized pipes and low pressures. The system should be modified using the design criteria of velocity, pressure. To retrieve the situation there is a need to intervene. Modification in operation and design will improve the current situation of the case study water distribution system.
