Background Leakage Assessment for BBLAWN

Proposed solution approach is based on trial and error methodology using heuristic methods with simulation. To achieve the optimal solution, customized researched tools were developed for WDS optimization. Custom research tools are based on the TOOLKIT for the EPANET2. For design decisions also commercially available tools are used, carrying out comparison of various network structures (parallel pipe alternatives). The final result includes the change in 5 pipe diameters/pipe roughness coefficient C value; the installation of 80 pressure reducing valves and the change of 2 pump elements. Pumping schedule based on water tank levels was also optimized.
