Abstract
In the context of sustainable development effort, the water supply systems in the rural area of Constanta County should be optimally designed, so that their safe, efficient operation is assured. The results obtained by numerical simulation showed that Movila Verde -Independenta water supply duct might be subject of cavitation occurrence during hydraulic shock. Further investigations showed that the duct is adequately protected by a relatively short closing law of the check valve and three air valves mounted in the nodes where cavitation might occur. Minimal pressure increases from -10 mwc to -0.6 mwc because of these protection measures. Furthermore, the slight increase of maximal pressure does not require additional protection devices.
