The present paper provides a pilot example for water networks managers and operators intending to adjust the hydraulic condition of a pressurized water system to operations conditions with the objective to improve its efficiency. For this aim, a hydraulic modeling methodology has been applied and combined with site inspection, and field measurements. The selected water system operates under particular topographic and operational conditions and suffers from major problems making the system unable to deliver water with the designed volume to the regional reservoir. The system is studied under both steady and unsteady conditions. The study shows benefits of the proposed methodology in terms of water loss reduction which allows enhancing the hydraulic performance of the system. Consequently, the adjustment of a water system to fit with the real operations conditions has improved the hydraulic reliability and efficiency of the system.
The novelty of this paper is two-fold. First, it gathers field measurements and hydraulic modeling. Second, it forecasts and measures the efficiency of proposed rehabilitation works by checking the performance of the water system. Therefore, the paper results can be useful to researchers in hydraulics who need an identification of relevant studies, as well as to practitioners interested in understanding the available methods, techniques and tools and their applicability level in real case studies.
